Newer methodologies have increased the incidence of coronary interventions. At the authors' institution, 5,614 coronary interventional procedures (28% of all catheteriza tions) were performed over a 3-year period, from 1995 to 1997. Eighty-one patients (1.4%) suffered angiographic accidents, including coronary artery dissection, free rupture, tamponade, foreign body embolism, and wire entrapment, and were retrospec tively reviewed. All patients were taken for emergency surgery in less than 4 hours. The mean age was 61.2 years, 44 (54%) were men, and 37 (46%) were in cardiogenic shock at the time of surgery. Fifty-seven patients (70%) had intraaortic balloon counterpulsa tion. The number of previous cardiac interventions ranged from one to four with a mean of 1.9. One to five bypass grafts (mean, 2.2) were performed, and three patients required temporary ventricular assist devices. There were six deaths for a 30-day mortality rate of 7.4%. Thirty-two patients (39.5%) suffered significant morbidity, including cerebrovas cular accidents, and renal and respiratory failure. Perioperative myocardial infarctions were diagnosed in 39 (48%) patients. Average length of stay was 12.1 days. One-year survival was satisfactory at 90% (73/81), with 56 survivors (77%) regaining normal everyday activity. Early surgical intervention, rapid revascularization, and temporary mechanical support are keys to low mortality in this high-risk group. Identification of high-risk interventions and significant comorbid conditions, with concomitant surgical consultation, need to be pursued to reduce the high morbidity rate.
