INTRODUCTION. The objective of present paper was to expose and to compare the results from two-ways different approaches (left anterior thoracotomy and longitudinal medium sternotomy) for myocardial revascularization with the heart beating carried out in the "Hermanos Ameijeiras" Clinical Surgical Hospital between September, 2007 (when this technique was introduced by thoracotomy ) and January, 2008. METHODS. A longitudinal, descriptive and prospective study was conducted to compare the results depending on the surgical approach for minimally invasive myocardial revascularization: usual route, by longitudinal medium sternotomy (29 operated on, 65,9%) and the new rout and unusual by left anterior thoracotomy (15 operated on, 34,1%). RESULTS. The average of shunts carried out was of 3,31 by sternotomy and of 3 by thoracotomy. The 96,6^ and the 26,7% of operated on sternotomy and thoracotomy, respectively need blood transfusions which was statistically significant. The use of inotropic drugs and of intra-aortic balloon counterpulsation hasn't statistical significance. The usual surgical time in both techniques was of 5 to 7 h, whereas the intubation was greater in patients operated on using sternotomy (11-14 h versus 3-6 h in the thoracotomy). The hospital stay was greater in the cases of sternotomy ( 3-4 days versus 1-2 days in those of sternotomy. There weren't statistical difference when complications and mortality were compared. CONCLUSIONS. The approach route using thoratocomy for myocardial revascularization is a alternative, effective and safe technique. It is possible to carry out a complete myocardial revascularization without compromising the procedure safe and he anastomoses quality. The costs are less using this route than with the usual one and the results are similarly significant as regards hospital stay and the use of hemoderivatives, thus, authors propose to continue working in the stabilization of this new route or coronary surgery in our service.
