Background:An isolated bicuspid aortic valve(BAV)is associated with structural and functional abnormalities of the aorta and the left ventricle(LV).Although~50%of patients with aortic coarctation(CoA)have a BAV,less is known about its impact on LV function and aortic geometry and function in CoA *** this cardiovascular magnetic resonance imaging(CMR)study,we analysed markers of LV and aortic function as well as aortic geometry in a large cohort of CoA patients with a BAVand compared them with CoA patients with a tricuspid aortic valve(TAV).Methods:We included 48 patients with a BAV(18.4±9.3 years)and 45 patients with TAV(20.7±9.9 years).LV volumes,mass and ejection fraction as well as aortic distensibilty,pulse wave velocity(PWV)were measured from standard cine CMR and phase-contrast CMR images.2-dimensional CMR feature tracking(2DCMR-FT)was performed to measure longitudinal,circumferential and radial strain and strain rate of the *** arch geometry was classified as romanic,gothic and ***:LV volumes,mass and ejection fraction as well as aortic distensibility and PWV did not significantly differ between the BAV and the TAV *** was also no significant difference for LV global longitudinal,radial and circumferential strain and strain rate between both *** with a BAV had more commonly a gothic aortic arch compared to TAV patients,but this difference was not statistically significant(22 vs.14,p=0.2).Ascending and descending aortic distensibility correlated with LV mass in the entire patient group(paortic function in children and young adults with *** correlation of global circumferential,longitudinal and radial strain values with LV ejection fraction dem

bicuspid aortic valve Disease in Turner Syndrome: A Meta-Analysis of Prevalence

Turner syndrome patients partially or completely lack the X chromosome. 1 - 2500 female live births are affected. Clinical features include webbed neck, short stature, broad chest etc. bicuspid aortic valve disease (BAV) occurs in more than 30% of Turner syndrome patients causing significant morbidity and mortality. We aimed to establish a more reliable estimate of the prevalence of BAV in Turner syndrome. PubMed, Embase and PsycINFO databases were searched until 2022. Review Manager (RevMan 5.4.1) and the JASP software (0.16.00) were used for meta-analysis. 15 studies with a total of 3189 patients were combined. The pooled prevalence of BAV in Turner syndrome was 22.0% (95% CI: 15.0% - 29.0%). Sub group analysis by 45, X0 karyotype and age had prevalence of 24.0% and 8% respectively. The studies had high heterogeneity and possible publication biases. In summary, the study established that the prevalence of BAV in Turner syndrome patients diagnosed by echocardiogram, CT and MRI scans, is 22.0%, and 24% in patients with true monosomy 45, X0 karyotypes. Routine BAV exam should pay particular attention to monosomy 45, X0 karyotype patients, and where possible, CT and MRI should always accompany echocardiography for BAV screening, especially for pediatrics.

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） cm2）, 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.

Acquired Gerbode Defect Secondary to Severe bicuspid aortic valve Endocarditis

An annular aortic abscess is a fatal complication of infective endocarditis. Echocardiography is the initial imaging modality to confirm the diagnosis in suspected infective endocarditis. Here, we present a case of a bicuspid aortic valve infective endocarditis caused by Staphylococcus aureus and complicated with annular aortic abscess resulting in acquired Gerbode defect (type II) with tricuspid valve vegetation which was undiagnosed preoperatively. The intraoperative transoesophageal echocardiography yields a new finding prior to the surgical incision, which impacted the clinical decision-making and increased the burden of the procedure.
