A 74-year-old woman with severe aortic regurgitation, moderate mitral regurgitation, coronary artery disease status post bypass with left internal mammary artery to the left anterior descending coronary artery, and severe emphysema was deemed inoperable for open aortic valve replacement and underwent elective transcatheter aortic valve replacement. Because of the lack of annular calcium, the re...

Instantaneous ascending aortic blood flow was recorded at operation in five patients with severe, pure mitral regurgitation, and in nine dogs in which mitral regurgitation was produced experimentally under controlled conditions. In both the patients and the experimental animals, the pattern of aortic flow was abnormal during mitral regurgitation: peak flow occurred early, the percentage of tota...

A 38-year-old man was admitted with coingestive heart failure due to infective endocarditis. Echocardiography with color Doppler imaging revealed severe aortic regurgitation, mitral valve premature closure and diastolic mitral regurgitation. The flow of the diastolic mitral regurgitation was directed to the posterior wall of the left atrium through just behind the posterior mitral leaflet. The ...

Rate-corrected left ventricular ejection time was measured from the aortic pressure tracings of 171 catheterised patients with aortic valve area less than or equal to 1.2 cm2. In 50 patients with pure aortic stenosis, left ventricular ejection time in increased with decreasing valve area and was significantly higher (468 +/- 5 ms, mean +/- SEM) than in 13 normal subjects (435 +/- 5 ms). Additio...

Aortic Regurgitation is also known as Aortic Insufficiency (AI). It indicates the inability of the aortic valve. During diastole, the aortic valve allows blood flow in the reverse direction from aorta into the left ventricle. Regurgitation is due to incompetence of the aortic valve or any disorder of the valvular apparatus (e.g., leaflets, annulus of the aorta) ensuing in diastolic flow of bloo...

A fetus was diagnosed with regurgitation from the aorta into the left ventricle. A large aortico-left ventricular tunnel with aortic atresia was identified postnatally by echocardiography in a neonate suffering from severe heart failure. We successfully reconstructed the valve and closed the tunnel with a patch on his first day of life. At three-month follow-up, the baby is asymptomatic with mi...

From 1986 to 1988, balloon aortic valvuloplasty was performed in 32 patients with congenital valvular aortic stenosis. The patients ranged in age from 2 days to 28 years (mean +/- SD 8.3 +/- 5.9). One balloon was used in 17 patients and two balloons were used in 15 patients. Immediately after valvuloplasty, peak systolic pressure gradient across the aortic valve decreased significantly from 77 ...

Pulsed Doppler echocardiography was used to determine prospectively the prevalence of mitral, aortic, tricuspid and pulmonary regurgitation in 80 consecutive patients with mitral valve prolapse and 85 normal subjects with similar age and sex distribution. Mitral valve prolapse was defined by posterior systolic displacement of the mitral valve on M-mode echocardiography of 3 mm or more (40 patie...

BACKGROUND Chronic aortic regurgitation can lead to significant morbidity and mortality. For more than a century, numerous eponymous signs of aortic regurgitation have been described in textbooks and the literature. PURPOSE To compare current textbook content with the peer-reviewed literature on the eponymous signs of aortic regurgitation and to assess the role of these signs in clinical prac...

OBJECTIVE To assess immediate clinical and echocardiographic results of the use of cryopreserved aortic homografts for aortic valve replacement. METHODS Eighteen patients with aortic valve disease underwent aortic valve replacement, receiving a cryopreserved aortic homograft, 15 were male, 10 had aortic regurgitation, and 8 had aortic stenosis. Age ranged from 18 to 65 years (mean, 44.5 +/- 1...
