Myocardial revascularization without cardiopulmonary bypass is now a subject of increasing interest. The purpose of this paper is to present the results obtained during 15 years of experience. From September 1981 till March 1996,1549 patients we operated on without the use of cardiopulmonary bypass with an applicability of this alternative around 18% of the total revascularized patients in this period. The ages varied from 28 to 86 years (medium 57) with 1126 males and 423 females. The number of grafts varied from 1 to 5 (medium 1.7 grafts/patient). The technique did not constitute special limitation to use arterial grafts. The thoracic internal arteries were used 1140 times. In 1515 patients the revascularization was achieved through medsternotomy and in 34 through a minor left anterior thoracotomy. The mortality rate was 2.4% (38/1549) the main primary cause of death, low cardiac output in patients operated under acute ischemia after failed angioplasty or evolving mycardial infarction. In 8 patients the revascularization was performed under intraaortic balloon pump. The results of this 15 years experience permit the conclusion that myocardial revascularization without extracorporeal circulation is an excelent alternative of surgical treatment of coronary artery disease for a subset of patients with lower mortality and morbidity being specially indicated in high risk patients.
