Aneurysmal protrusion of the posterior leaflet of the mitral valve

摘要: Abstract In previous communications, evidence has been produced that apical late systolic murmurs are invariably due to mitral regurgitation, and the commonly associated nonejection clicks result from abnormalities of chordae tendineae. The present paper describes 5 patients with both these auscultatory findings who had, in addition, electrocardiographic signs compatible posteroinferior myocardial ischemia or infarction. Left ventricular cineangiocardiography was performed 4 patients, an aneurysmal dilatation posterior leaflet valve demonstrated. It is postulated distortion circumflex coronary artery by abnormal may be cause features. probability briefly discussed some instances anomaly results a genetically determined defect, weakness, leaflet.
