Intra-aortic balloon counterpulsation support for elective coronary angioplasty in the setting of poor left ventricular function: a two center experience

J Invasive Cardiol. Jul-Aug 1990;2(4):175-80.


A two-center elective coronary angioplasty experience with intra-aortic balloon pump support for patients with severe left ventricular dysfunction is reported. To prevent hemodynamic collapse, an intra-aortic balloon pump was inserted percutaneously before coronary angioplasty in 97 patients with a left ventricular ejection fraction less than 35% (26% of whom had ejection fractions less than 25%). The cohort was predominantly male (71%) with a mean age of 64 +/- 9 years. Angioplasty was successfully performed in 83 (85.6%) patients and 80 (82.5%) of these successful patients were discharged from the hospital. Seven patients had unsuccessful angioplasty without a major cardiac event. Seven patients (7.2%) suffered a major cardiac event; 4 had emergent coronary bypass surgery with q-wave infarction, 2 had uneventful emergency coronary bypass surgery, and one patient died in the operating room after a failed angioplasty. Using logistic regression analysis, the presence of multivessel disease and a history of prior myocardial infarction were associated with more complications during angioplasty (p less than 0.05). Intra-aortic balloon pump placement did not interfere with the angioplasty procedure. Two patients had limb ischemia which resolved when the intra-aortic balloon pump was removed. Of the 80 successful patients discharged, 72 were followed for a mean of 22 months. At the latest follow-up, 52 had not suffered a myocardial infarction and were alive. Of the 20 late deaths, 16 were cardiac and 4 non-cardiac.(ABSTRACT TRUNCATED AT 250 WORDS)
