Serial echocardiographic studies of Henry et al. (Circulation 61, 471 [1980]) in patients with chronic aortic regurgigation (AR) indicate that preoperative left ventricular end-systolic dimension (ESD) greater than 55 mm and fractional shortening (FS) less than 25% may identify patients with reduced postoperative survival. We retrospectively analyzed the onedimensional echocardiograms of 33 patients with AR without coronary artery disease who underwent operation from 1977 to 1981. Twenty-three patients with ESD less than or equal to 55 mm (group A, mean age 48 +/- 10 years) were followed 36 +/- 14 months postoperatively, ten patients with ESD greater than 55 mm (group B, eight patients with FS less than 25%; mean age 48 +/- 12 years) 40 +/- 10 months. In both groups there were no perioperative or late deaths. In group A the average preoperative NYHA functional class decreased from 2.6 to 1.4 postoperatively, in group B from 3.0 to 1.5 (A vs. B: NS). Preoperative FS was 35 +/- 8% in group A and 22 +/- 3% in group B, preoperative ESD 44 +/- 5 mm in group A and 62 +/- 7 in group B. Three years after operation, end-diastolic dimension was 54 +/- 8 mm compared with 68 +/- 5 mm preoperatively in group A (p less than 0.001) and 61 +/- 11 mm compared to 79 +/- 8 mm preoperatively in group B (p less than 0.001). According to these data, a significant postoperative decrease of end-diastolic dimension can be expected in most patients with AR and ESD greater than 55 mm. The long-term prognosis of this subgroup is not so impaired as to recommend aortic valve replacement to asymptomatic patients a priori.
