Abstract:
Abstract Aims Left atrial appendage (LAA) electrical isolation (LAAEI) in addition to pulmonary vein isolation is an emerging catheter-based therapy to treat symptomatic atrial fibrillation. Previous studies found high incidences of LAA thrombus formation after LAAEI. This study sought to analyse therapeutic strategies aiming at the resolution of LAA thrombi and prevention of thromboembolism. Methods and results Left atrial appendage electrical isolation was conducted via creation of left atrial linear lesions or cryoballoon ablation. Follow-up including transoesophageal echocardiography was conducted. In patients with LAA thrombus, oral anticoagulation (OAC) was adjusted until thrombus resolution was documented. Percutaneous LAA closure (LAAC) under use of a cerebral protection device was conducted in case of medically refractory LAA thrombi. Left atrial appendage thrombus was documented in 54 of 239 analysed patients who had undergone LAAEI. Thrombus resolution was documented in 39/51 patients (72.2%) with available follow-up after adjustment of OAC. Twenty-nine patients underwent LAAC and 10 patients were kept on OAC after LAAEI. No thromboembolic events or further LAA thrombi were documented after 553 ± 443 days of follow-up in these patients. Persistent LAA thrombi despite adaption of OAC was documented in 12/51 patients. One patient remained on OAC until the end of follow-up, while LAAC with a cerebral protection device was performed in 11 patients in the presence of LAA thrombus without complications. Conclusion Left atrial appendage thrombus formation is common after LAAEI. Adjustment of OAC leads to LAA thrombus resolution in most patients. Left atrial appendage closure in the presence of LAA thrombi might be a feasible option in case of failed medical treatment.

Abstract:
AbstractThe implantation of an occluder in the left atrial appendage (LAA) is an emerging therapy for the treatment of patients suffering from atrial fibrillation and with a contraindication to oral anticoagulation. The LAA occluder (LAAO) provides a reduction of the potential risk of strokes by thromboembolism. Currently, only a few CE-approved devices are available on the market and the number of clinical trials is comparatively low. Furthermore, there is currently no standardized test method available for testing functionality of the occluder, especially for testing safe anchorage and permeability. Therefore, the aim of this study is to establish an in vitro test method to prove anchorage mechanism and permeability regarding thromboembolism of the LAAO under physiological conditions. A standardized technical and fully parameterized silicone model of a LAA, based on studies of different morphologies and sizes, was developed. The LAA model was mounted onto the left atrial chamber of a commercial pulse duplicator system to simulate physiological hemodynamic conditions. The test was performed using the Watchman device (Boston Scientific, USA; size: 31 mm). The inner implantation diameter of the LAA model was designed according to a target compression of 10% for the Watchman device in the implanted configuration. Furthermore, thrombus-like particles (n=150, d=1,7±0,05 mm) were added to represent the flushing of thrombi out of the LAA after device implantation. Within several cycles it was confirmed that no particles were washed out of the LAA model with the implanted occluder leading to a full protection against thromboembolism. It could also be shown that the occluder is firmly anchored in the LAA. Pressure measurements with sensors in the left atrium and in the LAA distal to the occluder could also show that the occluder has no influence on the pressure conditions in the LAA.

Abstract:
Abstract Background The left atrial appendage (LAA) is the main source of thromboembolism in atrial fibrillation (AF). Transcatheter closure is non-inferior to warfarin therapy in preventing stroke. Case summary A patient with two consecutive strokes associated with AF was referred for transcatheter LAA occlusion (LAAO). Preprocedural cardiac CT and transoesophageal echocardiography demonstrated a spontaneously occluded LAA with a smooth left atrial surface, with stationary results at 6- and 12-month imaging follow-up. Warfarin was discontinued, and life-long aspirin instigated. Discussion Left atrial appendage occlusion has shown non-inferiority to warfarin for prevention of stroke, cardiovascular death, and all-cause mortality. No benefits from anticoagulation have been demonstrated in patients with embolic stroke of undetermined source. In the present case, we observed that the LAA was occluded and, therefore, treated with aspirin monotherapy assuming similar efficacy as transcatheter LAAO.

Abstract:
Aims and Objectives: The objective of this study was to assess the clinical feasibility of generating 3D printing models of left atrial appendage (LAA) using real-time 3D transesophageal echocardiogram (TEE) data for preoperative reference of LAA occlusion. Background: Percutaneous LAA occlusion can effectively prevent patients with atrial fibrillation from stroke. However, the anatomical structure of LAA is so complicated that adequate information of its structure is essential for successful LAA occlusion. Emerging 3D printing technology has the demonstrated potential to structure more accurately than conventional imaging modalities by creating tangible patient-specific models. Typically, 3D printing data sets are acquired from CT and MRI, which may involve intravenous contrast, sedation, and ionizing radiation. It has been reported that 3D models of LAA were successfully created by the data acquired from CT. However, 3D printing of the LAA using real-time 3D TEE data has not yet been explored. Methods: Acquisition of 3D transesophageal echocardiographic data from 8 patients with atrial fibrillation was performed using the Philips EPIQ7 ultrasound system. Raw echocardiographic image data were opened in Philips QLAB and converted to ‘Cartesian DICOM' format and imported into Mimics® software to create 3D models of LAA, which were printed using a rubber-like material. The printed 3D models were then used for preoperative reference and procedural simulation in LAA occlusion. Results: We successfully printed LAAs of 8 patients. Each LAA costs approximately CNY 800-1,000 and the total process takes 16-17 h. Seven of the 8 Watchman devices predicted by preprocedural 2D TEE images were of the same sizes as those placed in the real operation. Interestingly, 3D printing models were highly reflective of the shape and size of LAAs, and all device sizes predicted by the 3D printing model were fully consistent with those placed in the real operation. Also, the 3D printed model could predict operating difficulty and the presence of a peridevice leak. Conclusions: 3D printing of the LAA using real-time 3D transesophageal echocardiographic data has a perfect and rapid application in LAA occlusion to assist with physician planning and decision making.

Abstract:
Acute mitral valve injury following percutaneous left atrial appendage (LAA) occlusion is a rare, but potentially life-threatening complication. This report presents a case of severe mitral valve injury following left atrial appendage occlusion (LAAO) that required mitral valve replacement. The LAAO device successfully was removed, and the LAA was closed with a double-running polypropylene suture. In addition, the mitral valve was replaced with an artificial valve. The patient had an uneventful clinical evolution and was discharged 10 days after emergency surgery.

Abstract:
Objective In patients with atrial fibrillation, 90% of embolic strokes originate from the left atrial appendage (LAA). Successful exclusion of the LAA is associated with a lower stroke rate in patients with atrial fibrillation. Surgical oversewing of the LAA is often incomplete when evaluated with transesophageal echocardiogram (TEE). External closure techniques of suturing and stapling have also demonstrated high failure rates with persistent flow and large stumps. We hypothesized that the precise visualization of a robotic LAA closure (RLAAC) would result in superior closure rates. Methods Before robotic mitral repair, patients underwent RLAAC; the base of the LAA was oversewn using a running 4–0 polytetrafluoroethylene suture in two layers. Postoperatively, the LAA was interrogated in multiple TEE views. Incomplete closure was defined as any flow across the LAA suture line or a residual stump of greater than 1 cm. Results Seventy-nine consecutive patients underwent RLAAC; no injuries occurred. On postrepair TEE, 73 of 79 patients had LAAs visualized well enough to thoroughly evaluate. Successful ligation was confirmed in 64 (87.7%) of 73 patients. Seven patients (9.6%) had small jet flow into the LAA; no residual stumps were noted. Two patients (2.7%) had undetermined flow. Conclusions We have demonstrated excellent success with RLAAC; we postulate that this may be due to improved intracardiac visualization. Robotic LAA closure was more successful (87.7%) than previously reported results from the Left Atrial Appendage Occlusion Study for suture exclusion (45.5%) and staple closure (72.7%). With success rates equivalent to transcatheter device closures, RLAAC should be considered for robotic mitral valve surgical patients.

Abstract:
IntroductionInterventional closure of the left atrial appendage closure (LAAC) has been established as an alternative treatment in patients with atrial fibrillation (AF) and an increased risk of stroke. So far it is unknown whether the use of ultrasound contrast agent (UCA) would influence the correct sizing of the LAA and thereby have an impact on device selection during interventional LAAC.MethodsBetween January 2017 and April 2018, 223 transoesophageal echocardiography (TOE) examinations were prospectively performed in adult patients with non-valvular AF (Impact of the use of ultrasound contrast agent on the detection of thrombi in the left atrial appendage during transesophageal echocardiography (CONDOR) study). LAA was examined both with and without the use of UCA. The following measurements were taken at 0o, 45o, 90o and 135o: diameter of LAA ostium, maximal depth of the LAA, maximal available depth of the LAA orthogonal to the ostial plane and area of the LAA.ResultsThe use of UCA had no relevant influence on the size determination of the LAA. Additionally, Bland-Altman blots demonstrate a high degree of correlation between the measurements with and without UCA with no evidence for a systematic effect arising from the use of UCA. When comparing the measurements of two independent investigators, the use of UCA rather leads to a higher variability than to an improved precision.DiscussionDespite the fact that the use of UCA during TOE leads to an improved rule out of thrombi, our study shows that there is no advantageous effect of UCA on the size determination of the LAA and should therefore not be used for this purpose.

Abstract Abstract 3596 Immune phenotyping plays a critical role in the diagnosis and classification of acute leukemia. Several studies have reported a variable proportion of patients with acute myeloid leukemia (AML) expressing lymphoid-associated antigens (LAA). The exact frequency and true clinical significance of this phenomenon remains undefined due to inconsistencies between series, likely related to methodological aspects or potential case selection biases. We retrospectively evaluated the expression of LAA in blast cells from 278 consecutive and unselected patients with AML diagnosed in our Department between 2002 and 2010. The patient cohort included 168 males and 110 females with a median age of 61 years (range, 10–88); 146/278 cases were above the age of 60. Within this cohort, 190 cases (68%) had de novo AML, whereas the remaining 88 cases (32%) concerned secondary AML (sAML) to either MDS (n=80) or other non-hematologic malignancies (n=8). Patients were treated uniformly according to age with Aracytin/Idarubicin induction regimens (“3+7” or “2+5” for ages \q60 or ≥60, respectively). The immunophenotype was determined by flow cytometric analysis of (mainly) bone marrow aspirate and/or peripheral blood samples utilizing a primary CD45/side scatter (SSC) gating procedure with antibodies against CD7, CD13, CD19, CD33, CD4, CD10, CD34, CD117, CD64, HLA-DR, CD20, CD2, CD15, CD56, CD14, CD8, MPO, CD3, CD79a, CD22, TdT and lysozyme; a cut-off value for positivity of 20% was adopted. Overall, we identified 153/278 cases (55%) expressing at least one LAA. The most commonly expressed LAAs were CD4 (outside AML with monocytic differentiation), CD56, CD7, CD2, CD10 and CD79a (in 39%, 33%, 29%, 14%, 10% and 8% of LAA+ AML cases, respectively); interestingly, all CD79a-positive cases co-expressed at least one more LAA. A significant association was identified between LAA expression and cytogenetic profile: in particular, at least one LAA was detected in 37/50 cases (74%) with adverse cytogenetics (SWOG unfavorable and/or monosomal karyotype), compared to 24/41 (58%) cytogenetically favorable cases and 68/134 (51%) cytogenetically intermediate risk cases (p=0.01). No other statistically significant associations were found for LAA expression (positive vs. negative) in respect to age and complete remission (CR) rate. Furthermore, the frequency of LAA-positive cases was identical (55%) in both de novo AML (105/190 cases) and sAML (48/88 cases). Monoparametric statistical analysis was also performed individually for each of the six more frequent LAAs. Significant associations (p<0.05) were identified between: (i) CD7 expression and adverse cytogenetics; (ii) CD10 expression and adverse cytogenetics as well as failure to achieve CR, at both cohort level as well as patients \q60 years with de novo AML; and (iii) CD2 expression and shorter overall and disease-free survival (DFS and OS, respectively). Cox-multivariate analysis identified CD2 expression in addition to advanced age, sAML and adverse cytogenetic profile as negative prognostic indicators (p=0.05) for both DFS and OS. In conclusion, expression of LAAs is frequent in AML, among both de novo AML and sAML cases, and significantly associated with adverse cytogenetics. Although the negative prognostic impact of CD2 expression is noteworthy, however, the precise prognostic implications of the expression of individual LAAs are hard to define on single institution retrospective series and will require evaluation in large prospective and well-controlled studies. Disclosures: No relevant conflicts of interest to declare.

Abstract:
Background: Left atrial appendage (LAA) is usually the first site for thrombus formation in rheumatic heart disease (RHD). LAA function is altered in RHD which may predispose it to thrombus formation. The aim of this study was to determine an association between function of LAA and cardioembolic stroke.Methods:Total 132 patients with RHD were studied by means of transthoracic echocardiography and/or transesophageal echocardiography and left atrial (LA) size, LAA ejection fraction (EF) and peak flow velocities were measured. These patients were followed up for 18 months with reference to development of cardioembolic stroke.Results: Seventy nine patients had atrial fibrillation (AF), of which 34 had thrombus in LAA. Out of 53 patients with sinus rhythm, 5 had LAA thrombus. Mean LAA EF was significantly lower in patients with thrombus in LAA, so was the peak flow velocity (both variables p<0.0001). Saw tooth LAA outflow velocity pattern was visible in 30 (80%) patients with LAA thrombus versus 20 (28%) patients without LAA thrombus. Total 14 patients experienced cardioembolic stroke. Patients with cardioembolic stroke had lower mean LAA EF and peak flow velocity as compared to patients without cardioembolic stroke.Conclusions:Increased LAA size, reduced LAA EF and reduced peak flow velocity are associated with increased risk of cardioembolic stroke. LAA evaluation should be mandatory in deciding treatment strategies in patients with RHD and AF.

Abstract:
Introduction: Cardioembolic events are accompanied by left atrial appendage (LAA) in patients suffering from atrial fibrillation (AF); therefore, the LAA closure is implemented as a preventive strategy. The detection of LAA morphologies and function is a paramount step before establishing the LAA closure. Herein, we sought to determine the morphologic features of the LAA in an Iranian population using echocardiographic evaluation. Methods: Seventy-two near-normal heart patients were investigated by conducting a cross-sectional study. All patients were examined using the 2-dimensional and 3-dimensional transesophageal echocardiography (2D- and 3D-TEE) method. The anatomical features and functions of LAA were examined. All images were stored and analyzed offline. Results: The patients’ mean age was 39 ± 15.5 year and 33 (45.8%) were female. The most frequent shape of LAA was wind sock. More LAA lobes was observed in patients with AF compared to those with NSR. In comparison with AF group, the NSR had higher LAA flow velocity (P < 0.01). The paroxysmal AF had greater LAA flow velocity and LAA ejection fraction in comparison with the chronic AF (39 ± 19 vs. 75 ± 22, P < 0.01; and 49±4 vs. 72±14, P < 0.003; respectively). The paroxysmal AF had smaller systolic LAA orifice area in comparison with the chronic AF (P < 0.02). Conclusion: The morphologic features of LAA in Iranian population were within the range of other studies and LAA length and orifice diameters in 2D- and 3D-TEE were consistent. In addition, AF influenced the morphologies and functions of LAA compared to sinus rhythm.

Abstract:
Liverpool English, also known as Scouse, is an easily distinguishable accent, but whether or not it contains enough regionally specific grammar and vocabulary to be considered its own dialect is another matter. This Bachelor’s thesis set out to investigate this using a combination of qualitative and quantitative methods on data consisting of informal interviews found on the website Youtube with people from Liverpool. These videos were selected based on the assumption that people with discernible accents are most likely to also speak with a dialect. The results of the research showed that discerning whether or not Scouse is a dialect is not as straightforward as it would seem. Depending on the judgment of how many regional features are enough, the conclusion of this project was that the appearance of any items is sufficient to claim that Scouse is indeed a dialect.

Abstract:
The global mobile data usage has grown nearly 70\% annually in recent years. The huge mobile data usage requirement drives the mobile industry to brace the formidable challenge and invent next-generation mobile technologies. LTE, as a successful cellular technology, has gained tremendous importance in recent years due to its high data-rates and improved data access method for mobile devices. Even though LTE still may not be able to meet the mobile data challenge due to current spectrum scarcity in licensed bands. Thus, cellular network faces serious challenges to provide high performance mobile service to end users in the near future. In order to sustain the possible increase in mobile capacity demand, utilizing the unlicensed band as a supplementary band for LTE is being considered as a promising solution to expand the capacity of mobile systems. Based on the innovation of carrier aggregation, 3GPP has approved a study item on LAA-LTE, which will assist LTE by offloading mobile data in unlicensed band. Thus, LAA-LTE will operate in the spectrum that overlaps with WiFi, which is another popular unlicensed band technology. The concern is that LAA-LTE and WiFi are unlikely to have mechanisms to directly coordinate with each other, considering different core networks, backhauls and deployment plans of LAA-LTE and WiFi networks. The overarching goal of my research is to investigate the following two aspects: 1) Investigate how LTE will impact on WiFi using experimental analysis when both of them share the same channel, 2) Develop a possible coexistence algorithm to trigger the coexistence between LAA-LTE and WiFi in unlicensed band.

Mass spectrometry is a technique widely used in all prod uctive sectors. Since the late '80s with the emergence of soft ionization techniques, mass spectrometry has been widely disseminated in the analysis of biopolymers such as fatty acids, nucleic acids, oligosaccharides and especially proteins. Lectins are proteins of nonimmune origin that have at least one specific and reversible binding carbohydrate domain, without the ability to modify them. These proteins are widely distributed in nature. Lectins isolated from seeds of legumes are among the most studied and have high homology degree, being an important molecular marker of evolution in this clade. This study aimed to characterize some legume lectins by m ass spectrometry. Lectin EVA and LAA with 240 and 237 amino acid residues respectively, were analyzed for native mass and sequence of amino acids determined, showing a high degree of homology with other legume lectins. Lectin ConGF, a ConA-like, was analyzed for protein content in the crystal. Was determined that bot h mature chain and proteolytic fragments are present to form crystal, which indicates no difference between the chains structure covalently linked together by weak interactions. The partial sequence shows that ConGF has several structural features within the subtribe Diocleinae. All results demonstrate that mass spectrometry is a versatile and robust tool for characterizing proteins and can be successfully used to obtain structural information of lectins.
A espectrometria de massa à uma tÃcnica amplamente utilizada em todos os setores produtivos. Desde o final dos anos 80 com o surgimento de tÃcnicas de ionizaÃÃo brandas, a espectrometria de massa vem sendo amplamente difundida na anÃlise de biopolÃmeros como Ãcidos graxos, Ãcidos nuclÃicos, oligossacarÃdeos e principalmente proteÃnas. Lectinas sÃo proteÃnas de origem nÃo imune que possuem pelo menos um domÃnio de ligaÃÃo especÃfica e reversÃvel a carboidratos, sem a capacidade de modificÃ-los. Estas proteÃnas sÃo amplamente distribuÃdas na natureza. As lectinas isoladas de sementes de leguminosas estÃo entre as mais estudadas e possuem alta homologia, sendo importantes marcadores moleculares da evoluÃÃo dentro desta famÃlia vegetal. Este trabalho teve como objetivo caracterizar lectinas da famÃlia Leguminosae atravÃs de espectrometria de massa. As lectinas de Erythrina velutina (EVA) e Luetzelburgia auriculata (LAA) com 240 e 237 resÃduos de aminoÃcidos respectivamente foram analisadas quanto a massa molecular nativa e foi determinada a sequencia de aminoÃcidos. As estruturas primÃrias mostraram alto grau de homologia com outras lectinas de leguminosas. A lectina ConGF, uma ConA-Like, foi analisada quanto ao conteÃdo protÃico do cristal. O cristal està composto da cadeia madura alfa e seus os fragmentos proteolÃticos, o que indica nÃo haver diferenÃa entre a estrutura ligada covalentemente e as cadeias unidas por interaÃÃes fracas. A sequÃncia parcial demonstra que ConGF possui caracterÃsticas estruturais da subtribo Diocleinae. Todos os resultados demonstram que a tÃcnica de espectrometria de massa à uma ferramenta versÃtil e robusta para caracterizaÃÃo de proteÃnas e pode ser usada com sucesso para obtenÃÃo de informaÃÃes estruturais de lectinas.
