INTRODUCTION Quadricuspid aortic valve is a rare malformation, with an estimated incidence of 0.003 to 0.043% of all congenital heart disease. It usually appears as an isolated congenital anomaly, but may also be associated with other malformations, the most common being coronary artery anomalies. Current technology enables noninvasive diagnosis in most cases. This entity's natural history is p...

A case of isolated chronic severe aortic regurgitation with Jaccoud's arthropathy involving the foot is presented. The interesting feature of the case is the absence of history of acute rheumatic arthritis at any stage of the illness. The diagnostic and possible therapeutic significance of this otherwise uncommon and benign condition are discussed.
Commissural dehiscence of the aortic valve is a rare cause of aortic regurgitation. We report a 53-year-old male who had progressive aortic regurgitation and aortic root dilatation. A flap or intimal tear of the proximal aorta was absent with echocardiography and computed tomography. Transesophageal echocardiography revealed prolapse of the right and left coronary cusps with no intimal flap in ...
A quadricuspid aortic valve is rare and often incidentally found by echocardiography, surgically, or on post mortem examination. Aortic regurgitation is common and if severe enough can lead to symptoms of dyspnea. We report a case of a quadricuspid aortic valve, which was found by cardiac multidetector computed tomography during a pre-operative assessment for severe aortic regurgitation.
Six patients with early systolic closure of the aortic valve are described with mitral regurgitation, double outlet right ventricle, left ventricular diverticulum, congestive cardiomyopathy, Eisenmenger ventricular septal defect, and aortic regurgitation with an aneurysmal ascending aorta, respectively. None had evidence of subaortic stenosis. Early sytolic closure of the aortic valve is thus n...
MIYAZAWA, K., YAMAKI, M., ISHIKAWA, K., TSUIKI, K., KOBAYASHI, Y. and KATORI, R. Effects of Metaproterenol and Deslanoside on Hemodynamics in Aortic Regurgitation. Tohoku J. exp. Med., 1973, 110 (1), 81-87 Hemodynamic responses to administration of metaproterenol and deslanoside were studied in 5 and 3 patients with aortic regurgitation, respectively. Metaproterenol pro duced an increase in for...
Transcatheter aortic valve implantation (TAVI) removes the valvular impedance associated with aortic stenosis but can be complicated by significant aortic regurgitation. Using cardiovascular magnetic resonance we assessed the change in trans-aortic pressure gradient and regurgitant fraction 6 months post-TAVI and compared this to a surgical aortic valve replacement (SAVR) cohort. TAVI was super...
We read with great interest the report by Seiffert et al. (1) on the initial German experience with transapical implantation of a second-generation transcatheter heart valve for the treatment of aortic regurgitation. With the development of second-generation transcatheter aortic value replacement (TAVR) devices, TAVR indications have been expended to high-risk patients with pure aortic regurgit...
