Comparative cost of myocardial revascularization: Percutaneous transluminal angioplasty and coronary artery bypass surgery

Abstract

A consecutive series of 78 patients having percutaneous transluminal coronary angioplasty for single vessel coronary artery disease and 85 patients having single vessel coronary artery bypass graft surgery were followed up prospectively for 1 year. Days in hospital and angiographic and revascularization procedures were counted in the two groups of patients and total cost of care for 12 months was calculated using current billing levels. Angioplasty was initially successful in 74% of patients; because of initial failure in 26% and late restenosis in 18%, bypass surgery was ultimately needed in 23 of 78 patients having coronary angioplasty. Nevertheless, total cost of care per patient was 43% lower for those having angioplasty as an initial procedure for single vessel coronary artery disease.
