• To evaluate the role of quantitative two-dimensional echocardiography (2DE) in the preoperative assessment of patients undergoing left ventricular (LV) aneurysmectomy, we identified 37 patients who were studied with 2DE 1 to 56 (mean 12.6) days prior to surgery. Diastolic (Dd) and systolic (Ds) minor-axis dimensions at the base were measured and fractional shortening (FS) was calculated. Global and basilar half ejection fraction (EF) as measured from right anterior oblique left ventriculograms. At follow-up (mean 17.9 months), 27 patients were alive and clinically improved (group A) and 10 patients either died or were symptomatically unimproved (group B). Basilar half EF was significantly greater among patients in group A (0.50 ± 0.09) than in group B (0.37 ± 0.10) ( p < 0.001). Echocardiographic FS provided the best separation between groups. Mean FS was 0.25 ± 0.06 in group A and 0.15 ± 0.04 in group B ( p < 0.001). All seven patients with FS < 0.17 were in group B while 25 of 27 patients with FS > 0.17 were in group A ( p < 0.001). Considering all patients, basilar half EF and FS were highly correlated ( r = 0.84).
