- W2028245622 abstract "Quantitative angiographic findings were reviewed in 40 patients with significant mitral regurgitation classified into three etiologic groups: group I, primary mitral regurgitation (prolapse, ruptured chordae); group II, mixed stenosis and regurgitation of rheumatic origin; and group III, cardiomyopathic mitral regurgitation. For patients in both groups I and II, left ventricular end-diastolic volume was directly related to regurgitant fraction, and ejection fraction was generally well maintained. In contrast, patients in group III had a depressed ejection fraction (less than 0.40) and end-diastolic volume that was disproportionately increased in relation to the degree of regurgitation. Left ventricular end-diastolic pressure was a poor indicator of severity of regurgitation in all patient groups. There was a significant negative correlation between forward cardiac index and regurgitant fraction. There was significant relation, although with considerable variation, between the normalized V wave and regurgitant fraction. The graphs of chamber size, ejection fraction and hemodynamic measures plotted against the severity of regurgitation in different patient groups provide a perspective for interpreting the findings in individual patients." @default.
