    Abstract:
    Sixty-four consecutive patients with coronary artery disease who had resections of left ventricular scars during 1969 to 1973 were retrospectively identified. Extent of angiographic coronary artery disease was scored by the jeopardy score system. Size of the abnormally contracting segment (akinetic or dyskinetic in all) was measured as a percent of the end-diastolic ventriculographic perimeter (% ACS). Contractility of the non-ACS was expressed as the difference between the actual ejection fraction and that predicted by the spherical model of Feild and Dowling (excess ejection fraction, XEF.) Perioperative survival correlated with jeopardy score (21 of 27, jeopardy score less than or equal to 6; 19 of 37 jeopardy score greater than 6) and with XEF (30 OF 38, XEF greater than +0.10; 10 of 26, XEF less than or equal to "0.10). When XEF and jeopardy score were combined, the patients were separated into four subgroups with perioperative survival ranging from 89% to 33%. Long-term survival (minimum follow-up period 30 months) in the 40 perioperative survivors also correlated with jeopardy score (95% at 54 mo for jeopardy score less than or equal to 6; 49% for jeopardy score greater than 6). Survival was unrelated to whether or not aortocoronary bypass graft procedures had been done. It is concluded that survival following aneurysmectomy is predicted by two preoperative angiographic variables--the extent of coronary artery disease and the contractility of the non-aneurysmal portion of the left ventricle.
