In an era of rapidly expanding use of transcatheter aortic valve implantation (TAVI), the management of patients with bicuspidaortic valve (BAV) disease is far less well established than in those with trileaflet anatomy.
Bicuspidaortic valve (BAV), the most common congenital cardiac anomaly, predisposes individuals to aortic stenosis and regurgitation due to valve degeneration.
Background Bicuspidaortic valve (BAV) is the most common congenital heart defect in adults, often leading to complications such as thoracic aortic aneurysms and aortic stenosis. While BAV is frequently associated with 22q11.2 This study is aimed to assess the role of rare 22q11.2 region (18–24 Mb).
Genetic variants linked to a rare form of bicuspidaortic valve disease that affects young adults and can lead to dangerous and potentially life-threatening aortic complications have been identified by researchers at UTHealth Houston.
Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspidaortic valve disease.

Bicuspidaortic valve (BAV) is a common congenital heart condition that can lead to some valve-related complications, such as aortic stenosis and/or regurgitation, and is often associated with aortic root dilation.
Transcript of the video: Closure line of aortic valve on M-Mode echocardiogram, is seen as central line, while in bicuspidaortic valve, it is an eccentric closure, nearer to one of the walls of the aorta. This eccentricity of closure of the aortic valve leaflets, can be calculated using what is known as eccentricity index.
The goal of the BICATOR trial was to determine whether treatment with low to moderate dose atorvastatin is associated with progression of ascending aortic dilation, valvular dysfunction, or valve calcification in patients with bicuspidaortic valve.
BackgroundAortic valve calcium score is associated with hemodynamic severity of aortic stenosis. All patients underwent invasive mitral valve assessment via direct left atrial and left ventricular pressure measurement. Median diastolic mitral valve gradient was 9.4±3.4 or mitral valve gradient (r=−0.03;P=0.8).ConclusionsMAC

BACKGROUND:Data concerning the outcomes of transcatheter aortic valve replacement in type 0 bicuspidaortic stenosis (AS) are scarce. Ascending aortic diameter was the single predictor of 1-year mortality in type 0 bicuspid patients (hazard ratio, 1.59 [95% CI, 1.03–2.44];P=0.035). Poverall=0.765; 1 year: 1.4%
Transthoracic echocardiography revealed severe aortic and mitral regurgitation, with a left ventricular ejection fraction of 37% and a left ventricular end-diastolic diameter of 64 mm. Despite receiving long-term optimal medical management, there was no improvement in symptoms or severity of valvular regurgitation.
Mitral and aortic annular calcification is an age-related degenerative process that can result in severe mitral and/or aortic stenosis and/or regurgitation. Annular calcification not only increases the surgica.
Quadricuspid aortic valve (QAV) is rare. However, to repair a quadricuspid aortic valve is not as easy to realize as in bicuspidaortic valve. The surgical design is crucial to rebuild the stable structure.
This case report describes a 3-month-old male infant diagnosed with severe mitral stenosis (MS) and mitral regurgitation (MR) by transthoracic echocardiography. The male infant initially underwent complex mitral valve repair surgery.
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAIF) is a rare complication of infective endocarditis or aortic valve surgery. Surgical treatment is suggested, but the long-term follow-up of conse.
Objectives This study evaluates predictors of conduction abnormalities (CA) following transcatheter aortic valve implantation (TAVI) in patients with bicuspidaortic valves (BAV). Predictors of CA are well established among patients with tricuspid aortic valves but not in those with BAV. to 41.00; p=0.01.
In this view, you can see that mitral leaflets are thickened. This is anterior mitral leaflet, thickened, and in the closed position of mitral valve, when there should be no flow to the left atrium, you are seeing a jet, a mosaic jet, which has been traced out. This is the mitral regurgitation jet. Here it is the AR jet.
What are the procedural and clinical outcomes of balloon-expandable valves (BEVs) and self-expanding valves (SEVs) in Sievers type 1 bicuspidaortic valve (BAV) stenosis?
Douglas Weaver MD, MACC discuss the history of and complications associated with bicuspid valvuloaortopathy. In this interview, Hector I. Michelena, MD, FACC and W.
Here, this is the forward flow through the mitral valve in diastole in red. This is reverse flow from the aortic valve, that is aortic regurgitation jet. Area of the jet corresponding to the receiving chamber, that is left atrium, that is also deciding factor in assessing the severity of mitral regurgitation.
Background The clinical prognosis of mitral valve surgery at morning, afternoon, and evening is not yet clear. The aim of the study is to investigate the impact of different time periods of surgery in the morning, afternoon and evening on the short-term and long-term results of mitral valve surgery.
BackgroundThe potential impact of exercise on valvular function and aortic diameters in patients with a bicuspidaortic valve remains unclear. Echocardiography was used to assess aortic stenosis or aortic regurgitation and to measure diameters at the sinuses of Valsalva and ascending aorta. and 20.0%, respectively.
BackgroundBicuspid aortic valves are associated with ascending aortic pathology, but their impact on longterm outcomes, including aortic growth and adverse events, remains unclear.Methods and ResultsThis prospective cohortstudy included adult patients undergoing aortic valve surgery or ascending aortic surgery at a single center (20072013).

BACKGROUND:Patients with paradoxical low-flow, low-gradient severe aortic stenosis exhibit low transvalvular flow rate (Q), while maintaining preserved left ventricular ejection fraction. Severe mitral regurgitation (MR) also causes a low-flow state, adding complexity to diagnosis and management. P<0.001). P<0.001).
Patients with bicuspidaortic valves (BAV) are predisposed to the development of aortic stenosis. We performed a pairwise meta-analysis, comparing the efficacy of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in patients with BAV. to 4.58, p=0.04).
BACKGROUND:This study aimed to compare the incidence and prognostic implications of new-onset conduction disturbances after surgical aortic valve replacement (SAVR) in patients with bicuspidaortic valve (BAV) aortic stenosis (AS) versus patients with tricuspid aortic valve (TAV) AS (ie, BAV-AS and TAV-AS, respectively).

The DAIC team has learned of the passing of Alain Cribier, MD, FACC, heralded as the man who pioneered the first transcatheter aortic valve replacement (TAVR) in 2002, as well as the first transcatheter mitral commissurotomy in 1995 and the first balloon aortic valvuloplasty in 1986. He passed away Feb.
Procedure trends certainly suggest that we’ve entered the TAVR era, but a pair of new studies show that surgical aortic valve replacement (SAVR) is a far better option for many younger and healthier patients who are increasingly seen as TAVR candidates. Much of these SAVR declines occurred in patients with tricuspid aortic valves (from 84.5%
