dc.description.abstract | Twenty-three patients with hemodynamically significant aortic regurgitation (AR) underwent gated equilibrium radionuclide angiography to assess rest and exercise left ventricular ejection fraction (LVEF) before and after aortic valve replacement. Preoperatively, LVEF decreased from 54 +/- 3% at rest to 45 +/- 3% during exercise (p < 0.001). Two patients died at operation. Postoperatively, after 5.7 +/- 1.6 months, LVEF was 62 +/- 5% at rest and 60 +/- 4% during exercise (difference not significant). Exercise LVEF improved significantly postoperatively (p < 0.01). The patients were followed for a mean of 30 months (range 1 to 56), after valve replacement and during this period, 13 patients were in functional class I, 5 patients were in class II and 2 patients were in class III. One late death occurred and was unrelated to myocardial failure. Thus, in most patients with AR, exercise LVEF improves after aortic valve replacement. A preoperative decrease in LVEF during exercise in patients with significant AR does not predict a poor postoperative outcome. | en_US |
