[Surgical treatment of left ventricular aneurysm]

From April 1972 to Dec. 1993, 152 cases underwent operation for left ventricular aneurysm (LVA) in Fuwai hospital. There were 143 males and 9 females with mean age of 49 years. Patients underwent ECG, chest X-ray (C/T 0.42-0.71), echocardiogram (LVEDP 0.267-6.27 kPa and cardiocoronary angiography (LVEF13-69%). There were 58 cases (38%) in NYHA class II, 82 cases (54%) in class III and 58 cases (7%) in class IV preoperatively. The total operative mortality was 9% with 7% of the last six-year. The main cause of the death was refrectory low cardiac output syndrome. Univariate analysis showed that the operative risk factors included ventricular arrhythmias, preoperative congestive heart failure (< 1 month), poor NYHA class, A-V condaction block. 138 discharged cases were followed up from 2-215 months (mean 36). There were 11 late deaths. The five-year and ten-year survival was 90% and 55% respectively. At the latest follow-up 44 cases (35%) were in NYHA class I, 62 (49%) in class II, 6 (6%) in class III and 2 (2%) in class IV. Our report demonstrated CABG is an effective treatment with good early and late results for LVA.
