Abstract:
Hypertrophic cardiomyopathy (HCM) is common, inherited and characterised by unexplained thickening of the myocardium. The British Society of Echocardiography (BSE) has recently published a minimum dataset for transthoracic echocardiography detailing the core views needed for a standard echocardiogram. For patients with confirmed or suspected HCM, additional views and measurements are necessary. This guideline, therefore, supplements the minimum dataset and describes a tailored, stepwise approach to the echocardiographic examination, and echocardiography’s position in the diagnostic pathway, before advising on the imaging of disease complications and invasive treatments.

Abstract:
Echocardiography plays a major role in the diagnosis and management of hemodynamic compromise during the perioperative period. Both transthoracic and transesophageal echocardiography have been shown to improve outcomes after cardiac and noncardiac surgery. Teaching basic echocardiographic skills to perioperative physicians remains a challenging task. Thus far, simulation-based medical education has been proven useful in teaching specific procedural skills and management of infrequent catastrophic events. Simulation-based echocardiography education has the potential to facilitate clinical training in echocardiography. Several small studies have shown the benefits of echocardiographic simulation on developing psychomotor and cognitive echocardiography skills. Future research should focus on the impact of simulation on actual clinical echocardiographic performance in the operating room and ultimately, patient outcomes.

Abstract:
AbstractHypertrophic cardiomyopathy (HCM) is the most common non-ischemic cardiomyopathy, characterized by increased left ventricular wall thickness. Echocardiographic studies are essential for establishing the diagnosis, evaluating the extent of disease, and risk stratification. Echocardiography is also recommended in regular screening of the genotype-positive relatives. Two-dimensional, M-mode, and Doppler echocardiography are standard modalities in HCM diagnosis. Newer echocardiographic techniques as tissue Doppler, strain, and three-dimensional echocardiography are now widely used and can reveal subtle changes in the HCM patients. Echocardiography has given us a better understanding of the disease. In this review, we briefly profile the echocardiographic management of HCM in a clinical perspective.

Abstract:
Coronavirus disease 2019 (COVID-19) has been associated with a wide spectrum of cardiovascular manifestations. Since the beginning of the pandemic, echocardiography has served as a valuable tool for triaging, diagnosing and managing patients with COVID-19. More recently, speckle-tracking echocardiography has been shown to be effective in demonstrating subclinical myocardial dysfunction that is often not detected in standard echocardiography. Echocardiographic findings in COVID-19 patients include left or right ventricular dysfunction, including abnormal longitudinal strain and focal wall motion abnormalities, valvular dysfunction and pericardial effusion. Additionally, some of these echocardiographic abnormalities have been shown to correlate with biomarkers and adverse clinical outcomes, suggesting an additional prognostic value of echocardiography. With increasing evidence of cardiac sequelae of COVID-19, the use of echocardiography has expanded to patients with cardiopulmonary symptoms after recovery from initial infection. This article aims to highlight the available echocardiographic tools and to summarize the echocardiographic findings across the full spectrum of COVID-19 disease and their correlations with biomarkers and mortality.

Abstract:
Introduction/Objective. The purpose of the Echocardiographic Society of Serbia (ECHOS) national survey was to assess current echocardiography practice in Serbia, the availability of different echocardiographic techniques and self-perceived need for improvement at personal and institutional level. Methods. A survey comprising 20 questions about demographics, numbers and distribution of echocardiographic equipment and techniques, image acquisition and reporting standards as well as future educational preferences was sent to all ECHOS members via email. Results. A total of 106 members (42%) answered the survey. Echocardiographic examinations are most frequently performed by cardiologists and internal medicine specialists. Transesophageal echocardiography (TOE), stress echocardiography (SECHO) and speckle tracking echocardiography (SpTE) are available in approximately 20% of centers, three-dimensional echocardiography in 11%, while contrast echocardiography is practiced in only two centers. Less than a third of respondents always attach electrocardiographic electrodes and archive examinations. Almost all respondents (96%), always evaluate both systolic and diastolic function of the left ventricle (LV), although systolic LV function is frequently assessed (55%) using non-standard methods. The newer echocardiographic machines are more often available at university than non-university centers (87 versus 44%, p < 0.01). SECHO was perceived as the most needed technique at the institutional level, while SpTE and TOE were most often reported personal aspirations of the respondents. Conclusion. Advanced techniques, SECHO and TOE are needed but rarely performed outside the university hospitals in Serbia. In order to achieve a better adherence to standards of practice in echocardiography, the development of national guidelines and personal and laboratory accreditation seem warranted.

Abstract:
Although the overall survival of patients with dilated cardiomyopathy (DCM) has improved significantly in the last decades, a non-negligible proportion of DCM patients still shows an unfavorable prognosis. DCM patients not only need imaging techniques that are effective in diagnosis, but also suitable for long-term follow-up with frequent re-evaluations. The exponential growth of echocardiography’s technology and performance in recent years has resulted in improved diagnostic accuracy, stratification, management and follow-up of patients with DCM. This review summarizes some new developments in echocardiography and their promising applications in DCM. Although nowadays cardiac magnetic resonance (CMR) remains the gold standard technique in DCM, the echocardiographic advances and novelties proposed in the manuscript, if properly integrated into clinical practice, could bring echocardiography closer to CMR in terms of accuracy and may certify ultrasound as the technique of choice in the follow-up of DCM patients. The application in DCM patients of novel echocardiographic techniques represents an interesting emergent research area for scholars in the near future.

Abstract:
Most of the cardiac abnormalities which pediatricians come across, require echocardiography for confirming the diagnosis. Due to the introduction of 'point of care ultrasonography' and widespread availability of ultrasonography equipment in clinical care areas, pediatricians are able to diagnose some of these cardiac abnormalities; however, they are unable to make a prompt echocardiographic diagnosis by themselves in most of these cardiac conditions due to lack of echocardiography skills. Pediatric residents and consultants, especially those who are involved in providing care in pediatric emergency, pediatric ICU, and neonatal ICU, should learn the skills of basic echocardiography for making the quicker diagnosis of such conditions and improving patient care. Subcostal view echocardiography can detect many cardiac abnormalities through a single echocardiographic window. There is a need of formulating a need-based basic Echocardiography training program to be incorporated into the Pediatric residency curriculum.

Abstract:
Background: Echocardiography requires a high degree of skill on the part of the examiner, and the skill may be more improved in larger volume centers. This study investigated trends and outcomes associated with the use and volume of echocardiographic exams from a real-world registry database of heart failure (HF) hospitalizations. Methods: This study was based on the Diagnosis Procedure Combination database in the Japanese Registry of All Cardiac and Vascular Datasets (JROAD-DPC). A first analysis was performed to assess the trend of echocardiographic examinations between 2012 and 2016. A secondary analysis was performed to assess whether echocardiographic use was associated with in-hospital mortality in 2015. Results: During this period, the use of echocardiography grew at an average annual rate of 6%. Patients with echocardiography had declining rates of hospital mortality, and these trends were associated with high hospitalization costs. In the 2015 sample, a total of 52,832 echocardiograms were examined, corresponding to 65.6% of all HF hospital admissions for that year. We found that the use and volume of echocardiography exams were associated with significantly lower odds of all-cause hospital mortality in heart failure (adjusted odds ratio (OR): 0.48 for use of echocardiography and 0.78 for the third tertile; both p < 0.001). Conclusions: The use of echocardiography was associated with decreased odds of hospital mortality in HF. The volumes of echocardiographic examinations were also associated with hospital mortality.

Abstract:
Abstract This article provides comprehensive insights into the evaluation of simple congenital heart diseases (CHDs) in adults, emphasizing the pivotal role of echocardiography. By focusing on conditions such as congenital aortic stenosis, aortic coarctation, patent ductus arteriosus, atrial septal defects (ASDs), and ventricular septal defects (VSDs), the review underscores echocardiography’s intricate contributions to precise clinical decision-making. Echocardiography serves as the primary imaging modality, offering high-resolution visualization of anatomical anomalies and quantification of hemodynamic parameters. It enables tailored therapeutic strategies through its capacity to discern the dimensions, spatial orientation, and dynamic shunt dynamics of defects such as ASDs and VSDs. Moreover, echocardiography’s advanced techniques, such as tissue Doppler imaging and speckle tracking, provide detailed insights into atrial mechanics, diastolic function, and ventricular filling kinetics. Integration of echocardiographic findings into clinical practice empowers clinicians to create personalized interventions based on quantified ventricular function, which spans systolic and diastolic aspects. This approach facilitates risk stratification and therapeutic planning, particularly pertinent in heart failure management within the CHD patient population. In summary, echocardiography transcends its role as an imaging tool, emerging as a precision-guided instrument adept at navigating the complexities of simple CHD in adults. Its ability to expedite diagnosis, quantify hemodynamic impacts, and unravel multifaceted functional dynamics culminates in a comprehensive depiction of these conditions. The fusion of these insights with clinical expertise empowers clinicians to navigate the intricate pathways of CHD, crafting tailored therapeutic strategies characterized by precision and efficacy.

Abstract:
Echocardiography (echo) is a widely available method to obtain images of the heart, however, echo can suffer due to the presence of artefacts, high noise and a restricted field-of-view. One method to overcome these limitations is to use multiple images, using the "best" parts from each image to produce a higher quality "compounded" image. This thesis describes a new method to allow multiple 3D echo images to be compounded into a single better quality volume. I have proposed a definition for an "ideal" compounded image and have used this to guide the design of my compounding method, in particular designing a method to reduce the effect of image artefacts and to make use of larger numbers of images. My compounding method has been validated using phantom, volunteer and clinical images. The overall motivations for improving echo image quality are twofold: Firstly to provide clinicians with higher quality images which I hope will improve the accuracy of clinical decision making. Secondly to provide higher quality images for subsequent post-processing algorithms. A number of methods have been proposed to compound sets of ultra-sound images, all of which have reported improvements in image quality. However, previous 3D compounding methods have typically been applied to a relatively small number of images (most of them only use two images, and only one uses six images). I have investigated the effect of compounding with larger numbers of images. Results showed continued improvement in image quality up to ten images (the maximum number we deemed feasible to acquire in a clinical setting and it is approximately double of images used previously). Artefacts occur regularly within echo images, particularly shadowing artefacts (due to the highly reflecting interfaces caused by the ribs and lungs when imaging the heart). However, previous 3D compounding methods haven’t directly claimed and demonstrated the effect of artefacts. Therefore, I have proposed a 3D compounding algorithm which specifically aims to reduce the effect of echo artefacts (shadowing) as well as improving the signal-to-noise ratio, contrast, and extending the field-of-view. My method to reduce the effect of artefacts is to weight image information from different views based on a local feature coherence/consistency. I hypothesize that the presence of an artefact in an image varies greatly depending on view direction, therefore much lower consistency values will be calculated for artefact regions enabling them to be detected, and their influence on the compounded image to be greatly reduced. The accuracy of the image registration is important and errors will likely affect the final compounded images quality. In addition to registration ac-curacy my system needs to work robustly and have a large enough capture range to enable automatic registration from a suitable starting position.

Abstract:
Heart disease is the major cause of death in the developed world. Due to its fast, portable, low-cost and harmless way of imaging the heart, echocardiography has become the most frequent tool for diagnosis of cardiac function in clinical routine. However, visual assessment of heart function from echocardiography is challenging, highly operatordependant and is subject to intra- and inter observer errors. Therefore, development of automated methods for echocardiography analysis is important towards accurate assessment of cardiac function. In this thesis we develop new ways to model echocardiography data using Bayesian machine learning methods and concern three problems: (i) wall motion analysis in 2D stress echocardiography, (ii) segmentation of the myocardium in 3D echocardiography, and (iii) standard views extraction from 3D echocardiography. Firstly, we propose and compare four discriminative methods for feature extraction and wall motion classification of 2D stress echocardiography (images of the heart taken at rest and after exercise or pharmalogical stress). The four methods are based on (i) Support Vector Machines, (ii) Relevance Vector Machines, (iii) Lasso algorithm and Regularised Least Squares, (iv) Elastic Net regularisation and Regularised Least Squares. Although all the methods are shown to have superior performance to the state-of-the-art, one conclusion is that good segmentation of the myocardium in echocardiography is key for accurate assessment of cardiac wall motion. We investigate the application of one of the most promising current machine learning techniques, called Decision Random Forests, to segment the myocardium from 3D echocardiograms. We demonstrate that more reliable and ultrasound specific descriptors are needed in order to achieve the best results. Specifically, we introduce two sets of new features to improve the segmentation results: (i) LoCo and GloCo features with a local and a global shape constraint on coupled endoand epicardial boundaries, and (ii) FA features, which use the Feature Asymmetry measure to highlight step-like edges in echocardiographic images. We also reinforce the traditional features such as Haar and Rectangular features by aligning 3D echocardiograms. For that we develop a new registration technique, which is based on aligning centre lines of the left ventricles. We show that with alignment performance is boosted by approximately 15%. Finally, a novel approach to detect planes in 3D images using regression voting is proposed. To the best of our knowledge we are the first to use a one-step regression approach for the task of plane detection in 3D images. We investigate the application to standard views extraction from 3D echocardiography to facilitate efficient clinical inspection of cardiac abnormalities and diseases. We further develop a new method, called the Class- Specific Regression Forest, where class label information is incorporating into the training phase to reinforce the learning from semantically relevant to the problem classes. During testing the votes from irrelevant classes are excluded from voting to maximise the confidence of output predictors. We demonstrate that the Class-Specific Regression Random Forest outperforms the classic Regression Random Forest and produces results comparable to the manual annotations.

Abstract:
Medical ultrasound imaging is widely used to diagnose cardiacdiseases. The recent availability of real time 3D ultrasound posesseveral interesting challenges and opportunities, and the work of thisthesis is devoted to both challenges and opportunities. One of the key benefits of ultrasound imaging is that its images arereal time. This has been challenged with the recent introduction of 3Dimages, where the number of ultrasound beams is squared compared totraditional 2D images. One common way to alleviate this is byreceiving several closely spaced ultrasound beams from each pulsetransmission, which increases acquisition speed but affects the imagequality. Specifically, B-mode images are irregularly sampled and losespatial shift invariance while a bias in the Doppler velocityestimates causes a discontinuity in the velocity estimates in colorflow images. We have found that these artifacts can be reducedsignificantly by interpolation of the beamformed data from overlappingbeams, with the limitation of requiring at least twice the number ofbeamformers. We have also found that valvular regurgitation is one of thecardiac diseases that can benefit greatly from quantification ofseverity using 3D ultrasound. We have devised a modality that useshigh pulse repetition frequency 3D Doppler to isolate thebackscattered signal power from the vena contracta of a regurgitantjet. This measure is calibrated with a narrow reference beam insidethe jet to estimate the cross-sectional area of the vena contracta. Wehave validated this method with computer simulations, with an in vitrostudy and finally in vivo with 27 patients who had mitralregurgitation. We found that the cross-sectional area and regurgitantvolume of the vena contracta could be quantified without bias as long as the orifice was sufficiently large for a calibration beam tofit inside it. The severity of smaller regurgitations will beoverestimated, but this does not pose a clinical problem, as thesepatients can easily be identified by standard 2D Doppler examination and donot typically need further quantification. Finally, we have developed a new, fast 3D ultrasound simulation methodthat can incorporate anisotropic scattering from cardiac muscle cells. This approach is three orders of magnitudefaster than the most commonly used simulation methods, making it wellsuited for the simulation of dynamic 3D images for development and testingof quantitative diagnostic methods such as 3D speckle tracking andvolumetric measurements.

Abstract:
Transoesophageal echocardiography has become a widely used diagnostic imaging technique by virtue of its ability to yield high quality images of the heart and great vessels. This thesis is based on work performed between January 1991 and July 1992 during which novel applications of transoesophageal echocardiography were investigated in the intraoperative and critical care settings. The mechanism by which closed chest cardiopulmonary resuscitation (CPR) generates forward blood flow has long been debated. Use of transoesophageal echocardiography allowed the physiology of CPR to be elucidated in 18 human subjects with cardiac arrest. These observations supported the cardiac pump theory of CPR and suggested that transoesophageal echocardiography might be utilised to monitor the efficacy of CPR. A preliminary investigation of CPR performed with the active compression-decompression device is described. The pathophysiology of the fat embolism syndrome (FES) is poorly understood. Transoesophageal echocardiography detected intraoperative fat embolism in 24 patients with traumatic injuries, three of whom subsequently developed clinical evidence of FES. Paradoxical embolism through a patent foramen ovale occurred in one subject with fulminating fat embolism. These results support the mechanical theory of the aetiology of fat emboli, and suggest that transoesophageal echocardiography might be used to identify patients at greatest risk of FES. The role of transoesophageal echocardiography in monitoring regional and global myocardial function was explored in a study of the cardioprotective properties of acadesine in patients undergoing coronary artery bypass surgery. No differences were observed between the acadesine and control groups in the incidence of new regional wall motion abnormalities or in changes in the areas ejection fraction. The strengths and limitations of transoesophageal echocardiography are discussed.

Abstract:
Rheumatic heart disease (RHD) is a permanent heart valve condition resulting from an abnormal immune reaction to group A streptococcal (GAS) infection typically occurring in childhood. If left untreated, disease progression can result in irreversible heart valve damage, cardiac failure, stroke and premature death. Significantly, RHD is a preventable and treatable chronic condition which mostly effects disadvantaged populations across the world. Moreover, the continued persistence of RHD contributes to considerable amounts of preventable morbidity and mortality, predominantly among adolescents and young adults. The accurate detection of subclinical RHD in children and adolescents, however, remains hampered by the cost of diagnostic machinery and scarcity of trained personnel. Alternative RHD screening tests, which are both accurate and affordable, are therefore needed in many endemic areas. Recently, handheld echocardiography has become widely available with a variety of clinical uses. If shown to be sufficiently accurate, use of these handheld devices could potentially expand access to echocardiographic screening in RHD endemic areas. The research undertaken for this MPH dissertation compares the accuracy of handheld echocardiography for the detection of rheumatic heart disease to the reference standard using systematic review methods. The dissertation is structured into three parts. PART A is a research protocol which describes the background and process of the proposed review. This section details the quantitative methods to be used in the systematic review and meta-analysis of studies which assess the diagnostic accuracy of handheld echocardiography for rheumatic heart disease detection in children and adolescents. The proposed systematic review methods are based on those of the Cochrane Collaboration. PART B is an extended literature review which expands on some of the topics raised in the background section of the protocol. A more in depth insight into the context surrounding the proposed research is offered and its importance highlighted. By reviewing the current body of evidence, this literature review aimed to both describe and contextualise the global burden of rheumatic heart disease whilst providing a rationale for further research into better screening modalities. Similarly, it also sought to describe the importance of understanding rheumatic heart disease epidemiology so that future research and screening programmes may be targeted accordingly. PART C is a full systematic review of diagnostic test accuracy studies presented as a journal ‘ready’ manuscript in a format suitable for submission to PLoS ONE. The background to the systematic review is briefly summarised after which the results are then presented and discussed. The main findings, from seven included studies, provide some evidence for the potential of handheld echocardiography to increase access to echocardiographic screening for rheumatic heart disease. Lastly and in conclusion, implications arising from the findings of the review are posited and suggestions for future research offered.

Abstract:
Left ventricular ejection fraction is a physiological measure obtained by evaluating the cardiac phases of systole or diastole. This parameter represents the contractile capacity of the cardiac ventricular chambers, which several methods can measure, echocardiography being the most cost-effective. The correct ejection fraction assessment is critical for diagnosing and treating most cardiovascular diseases. Although using deep learning to estimate the ejection fraction significantly improves the method’s accuracy, there are still difficulties with its extensive application for several reasons. This paper proposes a deep learning pipeline for classifying echocardiographic images in systole or diastole, comparing its performance to the state-of-the-art. The proposed pipeline features a set of pre-processing methods suitable to echocardiographic images and a convolutional neural network tuned for the considered classification task. We also introduce a novel dataset of echocardiographic images without excessive pre-selection of images, thus presenting real-life conditions. We performed several experiments to assess the performance of our approach, through which it was possible to obtain an accuracy of 97.69% and a cross-entropy loss of 0.1883. Our convolutional neural network was able to classify systolic and diastolic images with accuracy similar to the benchmark in the literature. The proposed pipelines present pre-processing methods suitable for echocardiographic images, a convolutional neural network adjusted for the considered classification. However, our network is simpler than the reference, and the dataset is closer to real-life conditions, avoiding excessive pre-selection of images.

Abstract:
Review question / Objective: P:Subclinical Hypothyroidism(Age over 18); I:thyroid hormone replacement therapy; C:baseline(before-after study in the same patient); O:Cardiac diastolic function measurement by echocardiography. Condition being studied: Subclinical hypothyroidism is associated with anomalies left ventricular diastolic functions, however, there are still disputes about whether to use levothyroxine for treatment. This meta-analysis aimed to determine whether levothyroxine (LT4), commonly used to treat hypothyroidism, affects cardiovascular indices in SCH patients as measured by echocardiography.

Abstract:
Background: Patient-prothesis mismatch (PPM) is a serious potential complication following surgical aortic valve replacement (SAVR). If it develops, valve-in-valve transcatheter aortic valve replacement (TAVR) is a reasonable therapeutic option. However, there is low evidence on the management of small degenerated surgical bioprosthetic valves, not prone to balloon-valve fracture (BVF). Case Presentation: This case report presents a successful valve-in-valve TAVR in acute heart failure due to degenerative surgical bioprosthetic valve Trifecta (21 mm) that is not susceptible to BVF. Standard preparation for transfemoral TAVR with a self-expandable valve was conducted, including the over-the-wire pacing. Thereafter, a successful valve-in-valve primary implantation of the self-expanding, supra-annular valve Evolut R 26 (Medtronic™) has been achieved. Follow-up at 3 months showed mild paravalvular leak in the region with clinical and heart function improvements of the patient. Follow-up echocardiographic parameters showed the reduction of anterograde flow impairment and improved effective orifice area (~0.85 cm2/m2). Conclusion: In conclusion, supra-annular valve-in-valve TAVR is a potential therapeutic option for PPM of small degenerated surgical bioprosthetic valves which are not prone to BVF.
