RESUMO

From July, 1970, to December, 1973, manual endarterectomies were performed on 330 coronary arteries in 315 patients. The procedures were performed on either an elective or nonelective basis. The over-all hospital mortality rate was 1.27 per cent. Postoperative myocardial infarction occurred in 4.8 per cent of these patients. Postoperative catheterization was performed on 186 endarterectomized arteries; the average time of postoperative catheterization was 13.1 months after surgery. The over-all patency rate was 76.3 per cent. This experience suggests that endarterectomy is a safe and useful adjunct to saphenous vein bypass grafting procedures when used in a restricted fashion as detailed in this presentation.

RESUMO

Rupture of the posterior wall of the left ventricle is an unusual but often lethal complication following mitral valve replacement (MVR). We have encountered it six times with a 100 per cent mortality rate in a series of 1,154 operations for MVR. Sites of rupture were located at the base of the resected papilary muscle or close to the artioventricular groove in the area adjacent to the resected posterior mitral leaflet. T stongly indicates the overzealous resection of the mitral leaflets and papillary muscle as an important eitiologic factor. Other possible etiologic factors are discussed and important pitfalls to be avoided during MVR are stressed.

RESUMO

Single aorta-coronary artery vein grafts (bridge grafts) were constructed to two coronary branches with a side-to-side anastomosis in 250 patients. Most of these grafts were constructed between circumflex branches (96 grafts), circumflex and diagnol branches (47 grafts), and anterior descending and diagonol branches (79 grafts). The aim of the bridge graft is to decrease the number of anastomoses, decrease the operative time, and improve graft patency. The hospital mortality rate in this group of patients was 1.2 per cent, and the incidence of postoperative myocardial infarction was 3.6 per cent. One hundred ten patients were restudied after surgery; the average time of restudy was 1 year. Ninety-two grafts of 83.6 per cent had two anastomosis patent; 6 grafts (5.4 per cent) had one anastomosis patent; and in 12 grafts (10.9 per cent), both anastomoses were occluded. One hundred twenty-six associated grafts were studied all the same time; the patency rate was 84.1 per cent. From this experience, we believe the bridge graft is a useful procedure for bypassing the small coronary artery branches.

RESUMO

A simple technique for internal mammary--coronary artery anastomosis that can be applied to all branches of the coronary circulation is described. The anastomosis can be constructed in 10 to 15 minutes. This technique eliminates pinching of the internal mammary artery by forceps.

RESUMO

From November, 1971, to September, 1974, 1,179 patients received aortocoronary saphenous vein bypass grafts at the Cleveland Clinic Hospital. Segments of saphenous vein from each patient were sent for microscopical analysis. These vein segments were classified as normal or abnormal (phlebosclerotic). Four hundred ninety-six normal vein grafts in 295 patients were restudied and had a patency of 87.9%. One hundred forty-four abnormal vein grafts in 86 patients were restudied and showed 89.5% patency. This study suggests that histopathological identification of an abnormal (phlebosclerotic) vein segment does not constitute a determining factor as far as late patency is concerned in a vein segment that is not grossly sclerotic.

RESUMO

Experiences with 265 consecutive patients 65 years of age and older who underwent myocardial revascularization surgery have been presented. With proper patient selection, expeditious surgery, and good postoperative management, good surgical results can be obtained that are comparable to any good risk group of patients. This study suggests that age alone is not a contraindication to aggressive surgical treatment of coronary artery disease.
