OBJECTIVE To determine the durability of repair of a bicuspid aortic valve with leaflet prolapse, and to identify factors associated with repair failure. METHODS From November 1988 to January 1997, 94 patients with a bicuspid aortic valve and regurgitation from leaflet prolapse had aortic valve repair. In 66 patients, the repair employed triangular resection of the prolapsing leaflet. The rem...

BACKGROUND Bicuspid aortic valve is frequent and is reported to cause numerous complications, but the clinical outcome of patients diagnosed with normal or mildly dysfunctional valve is undefined. METHODS AND RESULTS In 212 asymptomatic community residents from Olmsted County, Minn (age, 32+/-20 years; 65% male), bicuspid aortic valve was diagnosed between 1980 and 1999 with ejection fraction...

We present the case of a 51-year-old man who was admitted as an emergency with spontaneous thrombosis of the aortic valve and ascending aorta. At operation he was found to have a congenitally bicuspid aortic valve and subsequent investigation revealed primary antiphospholipid syndrome. He underwent successful removal of the thrombus combined with mechanical replacement of the aortic valve.

OBJECTIVE Long-term evaluation of the impact of bicuspid pulmonary valve on neoaortic valve regurgitation and aortic root dilatation (ARD) after arterial switch operation (ASO) for transposition of the great arteries (TGA). METHODS Between January 1987 and March 2010, 980 neonates underwent ASO for TGA. A total of 40 patients (4.0%) had a pulmonary bicuspid valve with no significant left vent...

Bicuspid aortic valve is the most common congenital cardiovascular anomaly, occurring in 1–2% of the population. It has a male predominance and often occurs in multiple members of the same family, suggesting that it may have an autosomal dominant inheritance, perhaps with variable penetrance. 2 Much of the data relating to its complications derive from necropsy studies since reliable diagnosis ...

A 22-year-old male patient was admitted to our institution because of repeated chest pain and syncope. Physical examination was unremarkable except for a systolic murmur on cardiac auscultation. Transesophageal echocardiogram showed a large, very mobile cystic mass (21×17 mm) attaching to the bicuspid aortic valve, which caused severe left ventricular outflow tract obstruction with normal ventr...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

Twenty-one patients (age four to 25 years) with bicuspid aortic valves proved by surgery and angiography (12) or angiography alone (9) were studied by echocardiography. Seventeen patients had aortic valve disease (11 stenosis, 6 incompetence) and four had coarctation of the aorta with normally functioning aortic valves. A comparison group of 16 patients (9 with aortic valve disease and 7 withou...

left ventricular outflow tract obstruction. In patients with predominant aortic regurgitation, especially those with bicuspid aortic valve or rheumatic fever associated with a geometric mismatch between the aortic and pulmonary valve due to dilated aortic annulus, the Ross procedure should be employed more selectively, and technical modifications that aim to prevent future annular and root dila...

OBJECTIVE To evaluate the early results of a new method to repair malfunctioning bicuspid aortic valves by creating a tricuspid valve with a crown-like (i.e. anatomic) annulus. MATERIAL AND METHODS Twelve patients (ages from 10 to 27 years) with chronic regurgitation (and flow-dependent stenosis) of a bicuspid aortic valve underwent repair with the principle of creating a tricuspid valve and ...
