title: Techniques and results of ventricular aneurysmectomy with emphasis on anteroseptal repair.
abstract: We have reviewed an 8 year experience with ventricular aneurysmectomy in 170 patients. Ninety percent had anterior aneurysms and underwent "anteroseptal repair" with exclusion of nonfunctioning septal myocardium. Preoperative left ventriculograms and coronary arteriograms were studied and "scored," and the hospital mortality and long-term survival rates for various subsets of the group were correlated with their radiographic data. A postoperative score for the coronary arteries was developed according to the preoperative anatomy and the vessels bypassed. Both the ventriculogram score and the postoperative coronary score had significant effects on both hospital mortality and long-term survival rates. The severity of preoperative coronary disease had minimal predictive value. Recent myocardial infarction did not preclude a good result. The value of an aggressive surgical approach to patients with ventricular aneurysm was confirmed even for certain subsets with indicators suggestive of poor prognosis. Anteroseptal repair appears to give optimal results for the typical "anterior" aneurysm. All suitable coronary arteries should be bypassed. Attention to the details of preoperative anatomy and function allows the most accurate prediction of prognosis and dictates the optimal therapeutic approach.
