• W1992505512 abstract "The purpose of the present study was to determine whether parameters of left atrial appendage (LAA) function, assessed by transesophageal echocardiography (TEE), could predict the clinical outcome in patients with dilated cardiomyopathy (DCM). Fifty-five patients (20 had ischemic cardiomyopathy; mean age, 56+/-14 years) who underwent TEE to evaluate LAA function from 1992 to 1996 were studied. After a mean follow-up period of 34+/-13 months, 16 patients died; the cause was cardiac in 14 and noncardiac in 2. Patients who died of cardiac cause had a lower LAA emptying velocity than survivors (38+/-18 vs 54+/-18 cm/s, p=0.01). There were, however, no significant differences between survivors and nonsurvivors with regard to the maximal LAA area (4.3+/-1.3 vs 4.5+/-0.9 cm2, p=0.55), minimal LAA area (2.4+/-1.1 vs 2.9+1.1 cm2, p=0.13), and LAA ejection fraction (46+/-16 vs 36+/-18%, p=0.05). On the Cox proportional hazards model analysis, LAA emptying velocity <50 cm/s (chi-square 5.9, p=0.02), LAA ejection fraction <43% (chi-square 5.6, p=0.02), female gender (chi-square 5.2, p=0.02), pulmonary artery wedge pressure > or =14 mmHg (chi-square 4.8, p=0.03), E/A ratio > or =1.3 (chi-square 4.6, p=0.03), deceleration time <148 ms (chi-square 4.6, p=0.03), and cardiothoracic ratio > or =54% (chi-square 4.3, p=0.04) were significantly related to cardiac death. The stepwise multivariate analysis revealed that LAA emptying velocity (chi-square 6.1, p=0.01) and gender (chi-square 5.4, p=0.02) were the independent predictors for outcome. In conclusion, the parameters of LAA function may be useful predictors of the clinical outcome in patients with DCM." @default.
