Echocardiography after reconstructive surgery for non-rheumatic mitral regurgitation.
The echocardiographic appearances of the mitral valve after reconstructive surgery for non-rheumatic mitral regurgitation have been studied. Twenty-two patients, divided into 3 groups, were studied. In group 1 there were 12 patients with ruptured chordae tendineae and/or anterior mitral leaflet perforation, who underwent chordal reattachment and plication of leaflets or commissures. After opera...
متن کاملPrinciples of reconstructive surgery in degenerative mitral valve disease.
Degenerative mitral valve disease is the most common cause of mitral regurgitation (MR) in developed countries. The most common etiologies of valvular regurgitation are Barlow's disease and fibroelastic deficiency. The mechanism of MR is type II dysfunction (leaflet prolapse) due to chordae elongation or rupture in most patients. Associated annular dilation is a common lesion in almost all pati...
متن کاملBioprosthetic Mitral Valve Regurgitation
The usefulness of two-dimensional color-Doppler flow-imaging (2D Doppler) in the detection, localization, and quantitation of bioprosthetic mitral valve regurgitation is uncertain. Mitral bioprostheses, before and after the creation of transvalvular (n = 33), paravalvular (n = 17), or combined (n = 23) defects, were mounted in a pulsed duplication system (flow rates, 2.5-6.5 1/min; pulse rate, ...
متن کاملFloppy Mitral Valve, Mitral Valve Prolapse, and Mitral Valvular Regurgitation.
It is well recognized that the floppy mitral valve (FMV) complex is the central issue in the FMV, mitral valve prolapse (MVP), and mitral valvular regurgitation (MVR) story. MVP associated with the FMV results from the systolic movement of portions or segments of the FMV complex into the left atrium (LA). Prolapse of the FMV results in unique forms of mitral valvular dysfunction and MVR. When t...
