[Effect of volume load of the left ventricle in aortic and mitral insufficiency on the geometry and function of the right ventricle].
Zeitschrift Für Kardiologie 1987 December
To investigate the effect of chronic left ventricular enlargement on right ventricular geometry and function, biplane cineventriculograms were analyzed in 23 patients with aortic regurgitation (AR) and in 17 patients with mitral regurgitation (MR). Left ventricular end-diastolic volume indices (LVEDVI) were elevated and significantly (p less than 0.05) different in patients with aortic regurgitation (AR) (190.2 +/- 65.2 ml/m2) and mitral regurgitation (MR) (148.7 +/- 40.1 ml/m2). Right ventricular end-diastolic volume indices (RVEDVI), however, were comparable and within the normal range (AR: 96.6 +/- 18.3 ml/m2, MR: 100.2 +/- 33.7 ml/m2). Mean pulmonary artery pressure was significantly (p less than 0.05) higher in patients with mitral regurgitation with 24.7 +/- 12.8 mm Hg (AR: 17.5 +/- 6.6 mm Hg). Six patients with mitral insufficiency had concomitant tricuspid valve insufficiency. In five out of six patients with tricuspid insufficiency, right ventricular afterload was significantly elevated. Only in patients with mitral regurgitation was a significant correlation (r) between left and right ventricular end-diastolic volume index found (RVEDVI = 0.7 X LVEDVI +1, r = 0.80). Moreover, in patients with MR, left ventricular end-diastolic volume index correlated with right ventricular end-systolic volume index (RVESVI = 0.4 X LVEDVI -8, r = 0.73). Right ventricular ejection fraction was significantly different (p less than 0.05) between patients with aortic and mitral insufficiency (AR: 53.7 +/- 8.9%, MR: 46.7 +/- 10.7%). Particularly in patients with normal left ventricular ejection fraction (greater than 50%) and mitral regurgitation, the incidence of a reduced right ventricular ejection fraction (less than 50%) was significantly higher (p less than 0.01) compared to patients with aortic regurgitation.(ABSTRACT TRUNCATED AT 250 WORDS)
