To characterize the longterm outcome in patients who had successful coronary angioplasty (PTCA) and those who had an unsuccessful, uncomplicated procedure followed by elective bypass surgery (BYPASS) between 3/78 and 6/81, late followup was obtained in 196 (140 PTCA and 56 BYPASS) patients. Mean time to followup was 12 years (range = 13–16). There was no difference between the groups in survival (PTCA – 84.8%; BYPASS – 88.9%), late myocardial infarction (PTCA – 11.3%; BYPASS – 13.0%) or freedom from angina at latest contact (PTCA – 84.1 %; BYPASS – 87.0%). In the PTCA group, 110 (78.6%) were definitively treated with one or more PTCA procedures. In the BYPASS group, 46 (82.1%) were definitively treated with one or more bypass surgeries. Twenty (14.3%) of the PTCA group crossed over to BYPASS and 8 (14.3%) of the BYPASS group crossed over to PTCA. In conclusion, PTCA and BYPASS strategies yield comparable longterm results. Crossover rates between the two therapeutic procedures are similar. It appears that repeat procedures and crossovers are important in sustaining the beneficial results for both procedures over very long periods of time.
