Effectiveness of intraaortic balloon pumping without cardiac surgery for patients with severe heart failure secondary to a recent myocardial infarction.
Twenty-five patients with class III or class IV left ventricular failure (Myocardial Infarction Research Unit criteria) after a recent myocardial infarction were treated with intraaortic balloon pumping between December 1, 1972 and December 1, 1976. Three patients had no improvement and died during pumping. Two patients with improvement died during at attempt at weaning from circulatory assistance. Of 20 patients successfully weaned, 6 died within 3 months, 5 of these within 10 days after the weaning procedure. Of 14 patients who survived for more than 3 months, 13 were alive on February 15, 1977. Twelve of these 13 were in functional class II and 6 had resumed professional activities. Intraaortic balloon pumping proved an effective method for treating severe left ventricular failure after an acute myocardial infarction. Even withour surgery, 14 of 25 patients survived 3 or more months after an acute infarction complicated by serious pump failure.
