Late survival following use of intraaortic balloon pump in revascularization operations.
The early and late results of intraaortic balloon pump (IABP) support in 197 patients with pure myocardial revascularization were analyzed. Group I, 61 patients, had IABP support initiated preoperatively; Group II, 99 patients, had IABP support in the operating room because of inability to be weaned from bypass; and Group III, 37 patients, had support instituted for persistent low cardiac output state in the postoperative period. The early results showed that 73% were discharged from the hospital and that delayed use of the IABP was associated with a high mortality and high rate of perioperative myocardial infarction. When the results between men and women were compared, no statistical difference was noted. After a mean follow-up of 18 months, there were 9 late deaths. Three were due to noncardiac causes. The two-year cardiac actuarial survival for the hospital survivors was 96% and all three groups had uniformly good symptomatic relief. After hospital discharge, the late results of patients who required use of the IABP in conjunction with pure myocardial revascularization were the same as for patients who did not require IABP support.
