ABSTRACT
We examined our first 390 rotational atherectomy procedures to determine success and complications rates of patients aged 80 or greater (Group I, N equals 35) as compared to those younger (Group II, N equals 355). Procedural success was achieved in 32/35 (91%) of Group I and 42/355 (96%) of Group II patients (p equals NS). Coronary artery bypass graft surgery was required in 2/35 (5.7%) of Group I and 7/355 (2%) of Group II patients. No deaths, Q wave infarctions, or perforations occurred in the elderly patients and only one of each was observed in the younger group. During clinical follow up (26 months, 3-50), 4/25 patients (16%) in the octogenarian group died. Two of the deaths were cardiac (including the only crossover to surgery). One patient who sustained a late non Q myocardial infarction was asymptomatic. Of the remaining 20 patients the anginal class was 0-II in 19 and III in one. Rotational atherectomy can achieve excellent short and long term outcomes in selected octogenarians. (c)2000 by CVRR, Inc.
