[Operative outcome of patients with left ventricular giant aneurysm: mid-term follow-up in 49 patients].

To assess the mid-term outcome of the patients with left ventricular aneurysm repaired, and analyze the factors influencing early and late mortality and morbidity.From January 1992 to November 1998, 58 patients underwent surgical repair for postischemic left ventricular aneurysm. In the 56 survivals, 49 patients (87.5%) were followed-up for an average of 47.6 months (the longest time was 90.0 months).Early mortality rate was 3.4% (2 patients). In the follow-up period (mean 47.6 +/- 22.4 months), 10 patients died. The 5-year survival rates were 63.7%. The left ventricular end-diastolic diameter and left ventricular ejection fraction were improved significantly 29.0 months after operation. There was significant improvement in mean NYHA (from class 2.5 +/- 0.7 to 1.3 +/- 0.5). Of the survivors, 43 (87.8%) were free from angina, and 7 had arrhythmias. Multivariate analysis showed that left ventricular end-diastolic diameter larger than 70 mm and left ventricular ejection fraction lower than 35% were independent risk factors. 33% patients were free from drugs.Left ventricular aneurysm repair is an important therapeutic intervention and can be performed successfully. Patients who could benefit from the operation are those with a normal postoperative contraction pattern. Cardiac surgical procedures;
