Short and long term survival of surgical treatment of left ventricular aneurysms: ten years experience.
Although surgical treatment of left ventricular aneurysms has been performed for a long time, it is still a point of debate. In this study, we investigated 159 patients who had undergone surgery for a left ventricular aneurysm in our clinic between 1985 and 1994. Perioperative mortality, long term survival rates, and parameters which probably affect these ratios were evaluated. All of the patients except one were followed by clinical records, mail or phone. Classic linear repair (111 cases), plication (46 cases), and Dor plasty (2 cases) were performed. Revascularisation procedure was also performed in 140 (88%) cases. The average number of distal anastomosis was 2.6. Twenty cases (12.6%) died in the perioperative period. The most important parameter which affected early mortality was the requirement for an intra-aortic balloon pump in the postoperative period. Mean follow-up duration was 47 +/- 35 months. Forty-two late deaths occurred in this period. The overall 5-year survival rate was 71%. Predictors for long term mortality were related to preoperative left ventricular function, presence of congestive heart failure, and poor functional capacity. The type of surgery did not affect short and long term survival. The functional capacity of the survivors was improved. In conclusion, surgical treatment of left ventricular aneurysms with classic linear repair and plication had acceptable short and long term survival rates and improved functional capacity. The most important predictor of survival in either the early or late postoperative period was preoperative left ventricular function.
