Cardiac Function Early after Left Ventricular Aneurysmectomy Correlated to Preoperative Data and Late Postoperative Course

Summary

Early postoperative hemodynamic evaluations of 10 patients after ventricular aneurysmectomy are presented. Two patients had associated aorto-coronary bypass grafts and in 8 patients at least 2 vessels were free of major lesions. One patient died 2 months after the operation from a preoperative cerebro-vascular accident. Of the 9 surviving patients, 5 are in class I and 4 in class II (NYHA classification); all except 1 enjoy normal physical and professional activities. Two of these patients died 2 years after operation of cardiac causes and one after 4 years of Laennec's cirrhosis.

The early hemodynamic data and the long-term clinical results are correlated to some of the preoperative indices of myocardial function, such as elevated left ventricular filling pressure and ejection fraction. Although early postoperative cardiac index and left ventricular stroke work index were low and left ventricular filling pressure elevated, these data correlate neither with the preoperative parameters of myocardial function nor with long-term clinical results.
