Résumé :
From 1975 to 1995, 4200 patients had bioprosthetic valve replacements (2240 aortic, 1607 mitral, 353 multiple) and 2038 had mechanical valve replacements (747 aortic, 928 mitral, 363 multiple). Freedom from major thromboembolism or both major thromboembolism and hemorrhage for aortic and mitral valve replacement at 15 years was significantly greater for bioprostheses than mechanical prostheses. Freedom from valve-related mortality and reoperation for both aortic and mitral valve replacements was the same for bioprostheses and mechanical prostheses. Advancing age increased overall mortality (all positions), valve-related mortality (aortic, mitral), major thromboembolism (aortic), thromboembolism and hemorrhage (aortic, mitral) but decreased reoperation (all positions). Coronary artery bypass grafting increased overall mortality (aortic, mitral) but not valve-related mortality, and it decreased reoperation rate (aortic, mitral). Overall mortality was not influenced by valve type in aortic or multiple valve replacement but it was decreased by bioprostheses in mitral valve replacement. Valve type did not influence valve-related mortality (all positions). Mechanical valves decreased reoperation only for aortic valve replacement but they increased major thromboembolism with and without hemorrhage for both aortic and mitral replacements. There is support for bioprostheses in aortic valve replacement and mechanical prostheses in mitral valve replacement but for neither in multiple valve replacements.

Résumé :
Reoperative aortic valve replacement is associated with increased morbidity. Valve-in-valve transcatheter aortic valve replacement offers a less invasive alternative to traditional reoperation. However, cases of valve failure after valve-in-valve transcatheter aortic valve replacement represent a complex surgical challenge. We present a case requiring a complex reoperative aortic valve replacement due to structural valve deterioration after multiple previous valve-in-valve transcatheter aortic valve replacements. We performed removal of 3 previous valve-in-valve transcatheter aortic valves, bioprosthetic leaflet excision, and intentional bioprosthetic fracture under direct vision for annular enlargement. This facilitated direct insertion of a new transcatheter aortic valve for expedient and successful management of recurrent aortic stenosis in a very high-risk patient. Creative use of leaflet excision, intentional bioprosthetic fracture, and insertion of a new transcatheter aortic valve under direct vision, proved efficient and successful in a high-risk patient with few surgical options.

Résumé :
Precise determination of the size of aortic annulus is very important for thepreoperative evaluation before aortic valve replacement. Objectives: To determine thepreoperative prosthesis size using echocardiography in patients undergoing aortic valvereplacement. Study Design: Prospective observational study. Setting: Ch. Pervaiz ElahiInstitute of Cardiology (CPEIC) Multan. Period: January 2013 to October 2014. Methods: (100patients) Aortic annulus sizes were measured with TTE one week before surgery and with thehelp of sizer per-operatively. The data was analyzed by using SPSS V16. Quantitative variableswere analyzed using mean and standard deviation and percentages were used for qualitativevariables. Dependent sample t test was used to see accuracy of TTE in measuring aortic annulussize. Results: Out of hundred patients, 84(84%) were male. Mean age of the patients was 33.77+13.17 years. 51% patients underwent isolated Aortic valve replacement; redo-operations weredone only in 4% patients. In 96% patient’s mechanical prosthesis was used and in 4% patient’sboiprosthesis was used for valve replacement. We found no significant difference in Aorticannulus measured pre-operatively with the TTE (23.54+ 3.54) and measured per-operativewith the sizer (23.96+3.36) with highly insignificant p-value 0.58.Aortic annulus size was almostsame measured by these two techniques. Conclusion: Aortic annulus size measured with TTEhelps to arrange the optimum size prosthesis before aortic valve replacement surgery.

Résumé :
Abstract OBJECTIVES We investigated whether the selective use of supracoronary ascending aorta replacement achieves late outcomes comparable to those of aortic root replacement for acute Stanford type A aortic dissection (TAAD). METHODS Patients who underwent surgery for acute type A aortic dissection from 2005 to 2018 at the Helsinki University Hospital, Finland, were included in this analysis. Late mortality was evaluated with the Kaplan–Meier method and proximal aortic reoperation, i.e. operation on the aortic root or aortic valve, with the competing risk method. RESULTS Out of 309 patients, 216 underwent supracoronary ascending aortic replacement and 93 had aortic root replacement. At 10 years, mortality was 33.8% after aortic root replacement and 35.2% after ascending aortic replacement (P = 0.806, adjusted hazard ratio 1.25, 95% confidence interval, 0.77–2.02), and the cumulative incidence of proximal aortic reoperation was 6.0% in the aortic root replacement group and 6.2% in the ascending aortic replacement group (P = 0.65; adjusted subdistributional hazard ratio 0.53, 95% confidence interval 0.15–1.89). Among 71 propensity score matched pairs, 10-year survival was 34.4% after aortic root replacement and 36.2% after ascending aortic replacement surgery (P = 0.70). Cumulative incidence of proximal aortic reoperation was 7.0% after aortic root replacement and 13.0% after ascending aortic replacement surgery (P = 0.22). Among 102 patients with complete imaging data [mean follow-up, 4.7 (3.2) years], the estimated growth rate of the aortic root diameter was 0.22 mm/year, that of its area 7.19 mm2/year and that of its perimeter 0.43 mm/year. CONCLUSIONS When stringent selection criteria were used to determine the extent of proximal aortic reconstruction, aortic root replacement and ascending aortic replacement for type A aortic dissection achieved comparable clinical outcomes.

Résumé :
AbstractCongenital anomalies of the aortic valve frequently necessitate intervention in childhood. The most common aortic valve pathologies present in childhood are aortic stenosis and insufficiency. Presentation of aortic valve disease depends on severity and presence of concomitant syndromes and valvular disorders. Treatment options are largely categorised as medical, percutaneous repair or surgical repair and replacement. Surgical techniques have been refined over the last few years making this the mainstay of treatment in paediatric cases. Whilst repair is considered in most instances before replacement, there are substantial limitations which are reflected in the frequency of reintervention and restenosis rate. Replacements are typically undertaken with tissue or mechanical prosthesis. The current gold-standard aortic valve replacement surgery is called the Ross procedure—where replacement is undertaken with a competent pulmonic valve and a simultaneous pulmonary homograft.Conclusion: In this review, we aim to outline the various surgical options and discuss efficacy and complications of various interventions. What is Known: • Congenital aortic valve defects repair options medically and surgically What is New: • Comparisons between surgical options for aortic valve repair including efficacy, risks and long-term outcomes.

Résumé :
Background Referral rates and outcomes of cardiac rehabilitation have not been evaluated in patients with transcatheter aortic valve replacement or compared with surgical aortic valve replacement. Method A retrospective cohort study was conducted in 488 patients who underwent transcatheter aortic valve replacement ( n = 199) and surgical aortic valve replacement ( n = 289) from a university-based statewide transcatheter aortic valve replacement/surgical aortic valve replacement program during 2015–2017. Cardiac rehabilitation consisted of supervised exercise, diet education, and stress and depression management. We compared changes from baseline in exercise duration and intensity during cardiac rehabilitation sessions, quality-of-life (36-Item Short-Form Health Survey), and psychosocial measures (anxiety, depression, mood, social support, and diet) between transcatheter aortic valve replacement and surgical aortic valve replacement patients using t-test and chi-square analyses. Results Of 488 patients, cardiac rehabilitation referral rates were similar at 41% (transcatheter aortic valve replacement 81/199 versus surgical aortic valve replacement 117/289), but enrollment rates were lower in transcatheter aortic valve replacement (27/199, 14%) versus surgical aortic valve replacement (102/289, 35%, p < 0.01). Among eligible patients, cardiac rehabilitation completion rates were lower in transcatheter aortic valve replacement (12%) than surgical aortic valve replacement (32%). Exercise intensity during cardiac rehabilitation improved in both groups in a similar fashion (transcatheter aortic valve replacement 1.03 ± 1.09 versus surgical aortic valve replacement 1.34 ± 1.15 metabolic equivalents), but increase in exercise duration was higher in transcatheter aortic valve replacement patients versus surgical aortic valve replacement patients (14.52 ± 6.42 versus 10.67 ± 8.38 min, p = 0.02). Improvement in physical composite score was higher in surgical aortic valve replacement versus transcatheter aortic valve replacement (8.72 ± 7.87 versus 2.36 ± 7.6, p = 0.02) while improvement in mental composite score was higher in transcatheter aortic valve replacement (8.19 ± 8.50) versus surgical aortic valve replacement (1.18 ± 7.23, p = 0.02). There was no significant difference between the two groups in improvement in psychosocial measures. Conclusion Cardiac rehabilitation enrollment was low in transcatheter aortic valve replacement patients versus surgical aortic valve replacement patients despite similar referral rates. Improvement in functional and quality-of-life performance was achieved in both transcatheter aortic valve replacement and surgical aortic valve replacement. Future studies should address obstacles for enrollment of transcatheter aortic valve replacement patients.

Résumé :
Objectives We aimed to present data regarding the current status and trends of valvular heart surgeries in Japan from the Japan Cardiovascular Surgery Database for the 2017–2018. Methods We extracted data on cardiac valve surgeries performed in 2017 and 2018 from the Japan Cardiovascular Surgery Database. We determined the trend in the number of aortic valve replacement procedures from 2013 to 2018. The operative mortality rates were calculated for representative valve procedures stratified by age group. Data regarding minimally invasive procedures and transcatheter aortic valve replacement in the Japan Cardiovascular Surgery Database are also presented. Results In conjunction with the dramatic increase in the number of transcatheter aortic valve replacements in 2017 and 2018, surgical aortic valve replacement also increased from 26,054 to 28,202. The operative mortality rate in first-time valve procedures was 1.8% in isolated aortic valve replacement, 0.9% in isolated mitral valve repair, and 8.2% and 4.6% in mitral valve replacement with biological prostheses and with mechanical prostheses, respectively. Regarding minimally invasive procedures, 30.8% of first-time isolated mitral valve plasty procedures were performed by a right thoracotomy. Although patients who underwent surgery by a right thoracotomy had better clinical outcomes, it was also apparent that patients who underwent surgery by a right thoracotomy had lower operative risk profiles. The overall mortality rates after transcatheter aortic valve replacement and surgical aortic valve replacement were 1.5% and 1.8%, respectively. Conclusion We have reported benchmark data on heart valve surgery in 2017 and 2018 from the Japan Cardiovascular Surgery Database.

Résumé :
With the expansion of transcatheter aortic valve replacement in low-risk patients, we sought to explore current implanters' predictions on the future of this therapy by sending a survey to a sample of 8,261 healthcare professionals using Internet-based software. The survey contained six questions regarding physician specialty and experience, transcatheter aortic valve replacement age cutoff, optimal treatment for low-risk patients, transcatheter aortic valve replacement valve sequence, and transcatheter aortic valve replacement concerns. The majority, 29% percent, of all respondents felt that transcatheter aortic valve replacement will become the first-choice therapy for all patients, regardless of age and 70% felt that the optimal treatment would be transcatheter aortic valve replacement, with transcatheter aortic valve replacement valve-in-valve if the first valve degenerates. Regarding the sequence of transcatheter aortic valve replacement valves, 78% preferred the Edwards Sapien 3 valve (ES-3) as the first transcatheter aortic valve replacement valve followed by either a second ES-3 or Medtronic Evolut valve. Despite the high acceptance of transcatheter aortic valve replacement, many respondents (56%) felt that surgical aortic valve replacement might still remain the preferred treatment in low-risk patients due to an unknown durability of transcatheter aortic valve replacement valves. A majority of implanters see transcatheter aortic valve replacement followed by valve-in-valve transcatheter aortic valve replacement as the first-line therapy for low-risk patients with severe aortic stenosis, but long-term durability of transcatheter aortic valve replacement is an unanswered concern.

<p><strong>Aim:</strong> The study was to determine the feasibility and safety of truly stentless aortic valve replacement with bovine pericardium sutured directly onto the aortic wall by using a holding device.<br /><strong>Methods:</strong> Seven patients with pronounced aortic stenosis and coronary artery disease who underwent aortic valve leaflets plasty with a xenopericardial patch by means of a holding device combined with CABG were recruited. <br /><strong>Results:</strong> The aortic valve was successfully re-paired in 7 patients. A normal function of the valve was confirmed by echocardiographic data obtained in all patients. No complications were observed during follow-up. Mean hospital stay was 17 (13; 35) days. No reoperation for the aortic valve was performed during follow-up. Hospital mortality was 0%. Mean follow-up was 759 days. Long-term survival rate was 86%. Freedom from structural valve deterioration, thromboembolism, endocarditis and reoperation ran to 100%. The peak gradient across the aortic valve in the late period was 30 (26; 42) mm Hg, peak speed amounted to 3 (2.8; 3.2), mean aortic regurgitation grade was 1±0.1 degree.<br /><strong>Conclusion:</strong> Truly stentless xenopericardial aortic valve replacement is a good alternative to standard aortic valve replacement. This method is safe with regard to freedom from reoperations, degenerative valve changes, thromboembolism, endocarditis in the early and late postoperative periods.</p>

Résumé :
Transcatheter aortic valve replacement (TAVR) is a well-established method for replacing native aortic valves; however, it was conceived for elderly patients with aortic valve stenosis, and the lack of data on long-term durability has led practitioners to restrict the use of TAVR to patients who have short life expectancies. Here, we describe the case of a 21-year-old woman who had undergone 3 previous open aortic valve replacements and who presented with symptoms of recurrent valvular failure. Transthoracic echocardiograms and computed tomographic angiograms revealed a degenerating aortic root homograft with substantial calcification, moderate-to-severe aortic valve stenosis, and severe aortic valve regurgitation. Open surgical valve replacement posed substantial risk to our patient, so we decided to perform valve-in-valve TAVR with use of the Edwards Sapien XT Transcatheter Heart Valve. The patient's pulmonary artery pressure, valvular regurgitation, and symptoms improved substantially thereafter. We found that valve-in-valve TAVR into a failing aortic root homograft was less invasive than repeat surgical valve replacement in this young patient who had congenital vascular anomalies and a complex surgical history.

Résumé :
Objective To improve the outcome of percutaneous valve replacement in aortic stenosis endovascular resection of calcified aortic valves will be necessary. In this study different sealing methods were evaluated. The focus of this research was feasibility and mechanical functionality in human anatomy. Methods The aortic valve isolation chamber (AVIC) is a catheter-based system to seal the aortic valve during resection, and was installed antegrade and retrograde. Firstly, AVIC was inserted antegrade via the cardiac apex in human postmortem models (n = 2), and secondly in porcine in vivo models under extra corporeal circulation (n = 5). Endoscopic inspection of the valve was recorded. AVIC was installed via a port system through the descending aorta. Micro- and macropathologies were performed. Results AVIC transapical deployment in the two human models took 3 and 4 minutes respectively and 2.2 ± 1.3 minutes in average in the porcine model. From the descending aorta, the deployment took 9.3 ± 5.5 minutes. Fluoroscopy and macroscopy demonstrated sealed chambers. Microscopic and histologic analysis demonstrated no profound damages of the surrounding tissue. Conclusion This study demonstrates the feasibility of transapical and retrograde endovascular sealing of the aortic valve in vitro and in vivo in nonbeating hearts.

Résumé :
Objective Transcatheter aortic valve replacement is now commercially available for intermediate-risk, high-risk, or inoperable patients with severe aortic stenosis. In this study, we investigated change in the safety and efficiency of the transcatheter aortic valve replacement procedure at our institution and patient outcomes comparing our first 100, second 100, and last 100 patients. Methods From March 2012 to June 2016, 544 patients underwent transcatheter aortic valve replacement at our center. Three hundred patients were selected for this study and were categorized in the following three groups: group A, first to 100th patient; group B, 101st to 200th patient; and group C, 444th to 544th patient. Preoperative, intraoperative, and postoperative data were collected. Results Three hundred patients, 162 male (54%) male and 138 female (46%) with a mean ± SD age of 79.10 ± 8.93 years and mean ± SD society of thoracic surgeons’ risk score of 7.47 ± 0.76 were included. Fluoroscopy time, operation time, and incision time significantly decreased form group A to group C (all P < 0.05). Mean of contrast volume was also the highest in group A and the lowest in group C ( P < 0.001). Acute kidney injury rate was 26% (n = 26) in group A versus 23% (n = 23) in group B ( P = 0.743), and only one patient in group C (group C vs. group B, P < 0.001). Strokes declined over time: five (5%) stroke in group A; two (2%) stroke in group B, and no patient in group C (group C vs. group B, P = 0.1, and group C vs. group A, P = 0.059). In-hospital mortality was 5% (n = 5) in group A, 4% (n = 4) in group B, and 1% in group C ( P = 0.21). Conclusions Progressive experience and technology advances with transcatheter aortic valve replacement procedures improved operators’ expertise, making the transcatheter aortic valve replacement more efficient and safer over time.

Résumé :
Background: Small aortic annulus (AA) is a big issue during aortic valve replacement (AVR), necessitating replacement of an undersized prosthetic valve especially with double valve replacement (DVR). Despite the fact that small aortic valve prostheses can lead to prosthesis-patient mismatch (PPM), there remains reluctance to perform aortic root enlargement (ARE) procedures, fearing morbidity and mortality. Objective: To evaluate clinical and echocardiographic outcomes in patients with small aortic annulus (<18 mm) undergoing double valve replacement. Methods: The study included 100 consecutive patients who underwent DVR for combined rheumatic aortic and mitral valve diseases, between January 2016 and September 2020. Only 50 patients had ARE with DVR. ARE was performed using an autologous or bovine pericardium or Dacron patch by Nick's or Manouguian procedures. The estimated postoperative endpoints were mortality, effective orifice areas (EOA), mean aortic pressure gradient (PG), and valve-related complications. The shortest postoperative follow-up period was 6 months. Results: The study included 30 male and 70 female patients with mean age of 35±20 years, body surface area (BSA) of 1.7 ± 0.3 m2, aortic annulus diameter was 1.4 ± 0.4 mm, aortic orifice area was 0.8 ± 0.1 cm2, and mean pressure gradient 85 ± 2.5 mmHg. During the follow-up period, there was a mild to moderate paravalvular leak (1%) with 1% heart block and residual gradient on prosthetic aortic valve; this was all in DVR alone. Conclusion: Enlargement of the aortic root by Nick's or Manouguian technique is safe and effective in patients with small aortic annulus undergoing double valve replacements.

Résumé :
In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A variety of aortic annulus enlargement techniques is reported to avoid patient-prosthesis mismatch. We present the case that has submitted four three times open heart surgery. We used Manouguian technique to enlarge aortic anulus with excellent results during the fourth time of surgery.
