“…As noted, the proportion of patients with a BAV (15 of 40, 37.5%) in this study was much higher than those of previous studies in Europe (3.0% to 9.2%) (Himbert et al, 2012;Hayashida et al, 2013;Bauer et al, 2014;Costopoulos et al, 2014;Kochman et al, 2014). This phenomenon has also been observed in almost every center that performs TAVI in China, and in some centers as many as 50% of the patients who underwent TAVI had a BAV.…”

“…However, BAV is the most common congenital heart disease, occurring in 0.5% to 2.0% of the general population (Roberts, 1970;Nistri et al, 2005;Tutar et al, 2005), and has been observed in about 50% of aortic valves resected during surgical aortic valve replacement (SAVR) (Roberts and Ko, 2005). Although several groups have reported the feasibility, efficacy, and safety of TAVI for patients with a BAV (Wijesinghe et al, 2010;Himbert et al, 2012;Hayashida et al, 2013;Bauer et al, 2014;Costopoulos et al, 2014;Kochman et al, 2014), global experience of the procedure is lacking, especially in China.…”

Abstract:Objective: The purpose of this study is to evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) in patients with a severe stenotic bicuspid aortic valve (BAV) in a Chinese population. While several groups have reported the feasibility, efficacy, and safety of TAVI for patients with a BAV, worldwide experience of the technique is still limited, especially in China. Methods: From March 2013 to November 2014, high surgical risk or inoperable patients with symptomatic severe aortic stenosis (AS) who had undergone TAVI at our institution were selected for inclusion in our study. Results were compared between a BAV group and a tricuspid aortic valve (TAV) group. Results: Forty patients were included in this study, 15 (37.5%) of whom were identified as having a BAV. In the BAV group, the aortic valve area was smaller ((0.47±0.13) vs. (0.59±0.14) cm 2 ), the ascending aortic diameter was larger ((40.4±4.4) vs. (36.4±4.3) mm), and the concomitant aortic regurgitation was lower. No significant differences were found between the groups in the other baseline characteristics. No differences were observed either in the choice of access or valve size. The procedural success achieved in this study was 100%. There were no differences between groups in device success (86.7% vs. 88.0%), 30-d mortality (6.7% vs. 8.0%), or 30-d combined end point (13.3% vs. 12.0%). The incidences of new pacemaker implantation, paravalvular regurgitation and other complications, recovery of left ventricle ejection fraction and heart function were similar in both groups. Conclusions: Patients with a severely stenotic BAV can be treated with TAVI, and their condition after treatment should be similar to that of people with a TAV.

“…BAV disease was an exclusion criterion in fundamental clinical trials to test the safety and efficacy of TAVI, largely because of the unique morphological features and associated aortic pathology of this condition 2, 3. Limited data exist for outcomes from TAVI in BAV and, despite promising single‐center series,4, 5 a recently published multi‐center series raised concerns about the excess of paravalvular regurgitation 6…”

“…55) Although O'Sullivan et al showed the implications of BAV for TAVI including case reports and current series, 56) we here summarized clinical series of the early outcomes of TAVI for BAV with the most recently published studies in Table 3. [52][53][54][57][58][59] Close preoperative and intraoperative analyses of the aortic valve anatomy are mandatory for successful TAVI in BAV cases. Further studies are needed to confirm the feasibility of implanting commercially available stent valves into selected bicuspid AS, and mid-term and long-term echocardiographic studies are mandatory in order to obtain more information on stent functioning in BAV in terms of stress, durability, leaflet tears, deterioration, dislodgement, malfunctioning, early stenosis, or paravalvular leaks.…”

IntroductionBicuspid aortic valve (BAV) is a common congenital cardiac malformation, with a reported incidence of between 0.6% and 2% in the general population. 1,2) BAV has been identified as the main cause of aortic valve disease leading to surgical treatment in children and young adults. A large pathological survey revealed that BAV could result in a stenotic lesion in 75% of patients and insufficiency in 15%. 3) Although BAV is often considered to be a benign lesion early in life, the complications associated with cardiovascular diseases, including aortic stenosis (AS), aortic insufficiency (AI), infective endocarditis (IE), and aortic dilation and dissection, can result in marked increases in morbidity and mortality later in life. [4][5][6] Understanding of aortic dilation associated with BAV has evolved with improvements in diagnostic technology and surgical management. 7) There is a growing consensus that the ascending aorta should be replaced at the time of aortic valve replacement for bicuspid aortic valve even if it is only moderately dilated. A recent study that gathered information from a total of 100 Canadian cardiac surgeons reported that surgeons' knowledge and attitudes toward BAV aortopathy influenced their surgical approaches. This large survey revealed significant gaps in the knowledge and attitudes of surgeons toward the diagnosis and management of BAV aortopathy, with approximately one third of cardiac surgeons stating that
