Between October 1995 and February 1996, sixteen patients were selected to undergo to surgical myocardial revascularization through left anterolateral minithoracotomy. The left internal thoracic artery was dissected in all patients, for consecutive anastomosis with interventricular anterior artery, without using extracorporeal circulation. Patients age ranged from 43 to 77, average 60 years. Sixty-two percent of them were men. There were no complications such as: acute myocardial infarction, mediastinitis, acute renal failure, hemorrhagy or stroke. There were no deaths. Four (25%) patients were submitted to cardiac catheterization that showed patency of grafts and grafted native arteries. Due to excellent initial results, the authors believe that this technique can be employed with greater frequency and that its use can be extended to the treatment of diagonal branches of the interventricular anterior artery and marginal branches of the circunflex, as soon as the surgical teams become more familiarized with it.
