RESUMO
A national study was carried out to determine the relative costs of PTCA and CABG. Baseline clinical criteria for the 2 groups were similar. Data were collected in 186 sets for the PTCA group and 175 sets for the CABG group. Male patients make up 81% of the PTCA group and 80% of the CABG group. Mean hospital stay was 12 +/- 5 days in the CABG group, compared with 4 +/- 2 days in the PTCA group (p less than 0.001). The base charges for hospital and professional components of the CABG procedure were $15,580 +/- $2,159, whereas the same charges for the PTCA procedure were $5,315 +/- $2,159 (p less than 0.001). With an 80% primary success rate, which was the group mean success rate, the average dollar savings per PTCA procedure would be $7,149, or $7,149,000 per 1,000 cases. Thus, PTCA for revascularization in 1-vessel CAD is significantly more cost-effective than CABG in the short term.

A computer program has been developed that can be used to quantify the extent of probable myocardial damage which will result from occlusion of a jeopardized coronary vessel. The program, used as an adjunct to coronary arteriography, permits calculation of an area of an arbitrary segment of the left ventricular epicardial surface. This segmental area, when expressed as a fraction of the total LV epicardial area, is a measure of the myocardial mass supplied by a specific coronary arterial vessel. The computer program has been extended to include graphic, three-dimensional simulation of different views of the left ventricular epicardium.
