OBJECTIVES In regurgitant tricuspid aortic valves, cusp prolapse may be isolated or associated with dilatation of the proximal aorta. Newly appearing cusp prolapse can also appear after an aortic valve sparing operation (AVSO) and be responsible for residual aortic regurgitation. In this report, we describe our experience in repairing prolapsing aortic cusps in 44 patients with aortic regurgita...
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent. During examination of operatively excised aortic and mitral valves because of dysfunction (stenosis and/or regurgitation), we encountered 16 patients who had congenitally bicuspid aortic valves associated with various t...
The association of sinuses of Valsalva dilatation and aortic regurgitation with hypertension is disputed, and few data are available in population-based samples. We explored the relations of sinuses of Valsalva dilatation and aortic regurgitation to hypertension and additional clinical and echocardiographic data in 2096 hypertensive and 361 normotensive participants in the Hypertension Genetic ...
INTRODUCTION Hemodynamic measurements can assess for paravalvular aortic regurgitation after transcatheter aortic valve replacement (TAVR). This study compared the utility of different invasive hemodynamic measures in providing prognostic information. METHODS This retrospective observational study of TAVR patients at a Veterans Hospital assessed aortic regurgitation index, diastolic delta, pu...
The purpose of this study was to evaluate the ability of continuous wave Doppler ultrasound recordings to reflect the magnitude and hemodynamic effects of aortic regurgitation. Forty-five patients with angiographically proved aortic regurgitation had Doppler studies performed within 24 hours of cardiac catheterization. High quality spectral recordings of the regurgitant jet were obtained in 31 ...
Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement (SAVR) in patients with severe symptomatic aortic stenosis at extreme or high surgical risk. We have previously reported that TAVR with a self-expanding aortic valve bioprosthesis in patients at increased risk for surgery was associated with better 1-year and 2-year survival compared...
RATIONALE Percutaneous aortic valve procedures are a major breakthrough in the management of patients with aortic stenosis. Residual gradient and residual aortic regurgitation are major predictors of midterm and long-term outcome after percutaneous aortic valve procedures. We hypothesized that (1) induction/recovery of high molecular weight (HMW) multimers of von Willebrand factor defect could ...
Between June 1969 and August I970, 8o patients, aged 22 to 63 years, had lone aortic valve replacement with frame-mounted autologous fascia lata. The operative mortality was 3.8 per cent. Seventy-seven survivors have been followed for 3 to 4 years and 50 have had postoperative investigation. There have been 8 subsequent deaths, 3 from infective endocarditis, 4 from aortic regurgitation, and one...
ALTHOUGH many techniques1-12 have been proposed or utilized for the semiquantitative or quantitative assessment of aortic regurgitation, the most direct approach involves measurement of the regurgitant flow by the recording of indicator concentrations from the left ventricle following injection into the aortic root. This method is theoretically valid13 and had been applied to aortic regurgitati...
Methods We retrospectively identified 97 consecutive patients with surgically corrected TOF and 26 controls without TOF or aortic or cardiac abnormalities who underwent cardiac MR evaluation. The ascending aortic diameter was measured at four levels and diameter ratios were calculated for morphologic characterization. Aortic pulse wave velocity (PWV) and aortic regurgitation were calculated fro...
