In animal models, severing the chordae tendineae of the mitral valve reduces the maximum
global left ventricular elastance (E max, g), a load-independent measure of left ventricular …

The aim of the present study was to elucidate the mechanisms of mitral regurgitation
accompanying myocardial infarction. Severity and site of mitral regurgitation was evaluated …

Previous angiographic observations in patients with mitral valve prolapse have suggested
that superior leaflet displacement results in abnormal superior tension on the papillary …

In patients with hypertrophic cardiomyopathy, the mitral valve moves anteriorly and assumes
a unique shape, with mitral-septal contact centrally and preserved valve orifice area …

Important advances in the understanding of pathophysiology, evaluation, and prognosis
have occurred during recent years and confirmed that ischaemic mitral regurgitation has …

Changes in mitral annular areas and cyclic area changes were measured in 17 patients with
mitral valve prolapse (MVP) and compared with those in 12 normal subjects. Using wide …

Clinical studies suggest that chorda-sparing mitral valve replacement techniques are
associated with superior postoperative outcome, and several animal experiments have …

F unctional mitral regurgitation (MR) is frequently observed in the setting of acute myocardial
infarction or chronic heart failure. Despite extensive characterization of this phenomenon, its …

High-speed biplane left ventricular (LV) cineangiograms were analyzed for changes in
volume, shape, and dimensions in 35 patients. Ventriculographic studies in ten normal …

The causes of mitral insufficiency are primarily considered from an anatomic point of view.
Mitral insufficiency may result from anatomic alteration of the papillary muscles, the chordae …
