      Abstract

      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 < 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 < 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.
