Does direct distal aortocoronary vein-grafting improve outcomes in patients with severe ischaemic heart disease?
Direct distal aortocoronary vein-grafting yielded good clinical results in a majority of patients with severe ischemic heart disease, though mortality and graft thrombosis were notable risks.
Abstract Direct distal aortocoronary vein-grafts have been used in 20 patients suffering form ischaemic heart disease. In 16 patients the indication for surgery was severe angina pectoris failing to respond to medical measures. Seven patients had angina decubitus and were Class IV according to the New York Heart Association classification and 9 patients were in Class III. Two patients had recurrent myocardial infarctions and 2 were in cardiac failure. There were 14 good results, 2 failures, and 4 deaths. Post-mortem studies of the hearts confirmed the accuracy of selective angiography in identifying the sites of major coronary obstruction. Findings at surgery showed that the absence r presence of extensive peripheral disease beyond a block could not be reliably assessed in all cases. Histological studies of the veno-arterial anastomoses suggested that rigid atherosclerotic arterial disease is a cause of graft thrombosis and that endarterectomy is a useful procedure though its longterm value is uncertain.
Bouch et al. (Sun,) conducted a observational in Ischaemic heart disease (n=20). Direct distal aortocoronary vein-grafts was evaluated on Clinical results (good results, failures, deaths). Direct distal aortocoronary vein-grafts in 20 patients with ischaemic heart disease yielded 14 good results, 2 failures, and 4 deaths.
