RESUMO
Coronary artery revascularization with cardiopulmonary bypass has been reported to carry several risks. Off-pump coronary artery bypass grafting has been proposed to result in a better outcome. The aim of this study is to assess the effect of off-pump cardiopulmonary bypass. In a 7-year period, a total of 100 patients undergoing isolated first-time off-pump coronary artery bypass graft were studied. The mean ejection fractions was 48% and the EUROSCORE mean was 4.9. The average number of grafts was 1.55 per patient. The postoperative outcomes were simple for most patients with little use of inotropes after 24 hours [42%], few cases of atrial fibrillation [9.4%], and transfusion [27.3%]. Time to extubation was less than 48 hours in most cases [94.7%] and hospital mortality rate was 10.5%.The beating heart bypass surgery allows good immediate results including multi-vessel disease and in patients at high risk
