ABSTRACT
We describe a case of coronary stenosis located in an unprotected left main coronary artery, treated primarily and electively with the placement of a coronary stent. As a function of the large mass of myocardium involved, this patient would be considered a classical candidate for direct surgery, because the inherent risk involved with conventional balloon angioplasty, mainly due to the eventual occurrence of acute closure during the procedure. Since the previsibility of the immediate results with the use of coronary stents was significantly improved, we propose this new therapeutic approach for this traditionally surgical case, that has been performed with success and without any complication. This strategy for the treatment of unprotected left main lesions with the elective placement of Palmaz-Schatz stents, has not yet been proposed or applied in our country, and may represent a new universe of indication of percutaneous treatment of coronary artery disease, no longer approaching the left main stem only in special or emergency situations, usually a result of complications of left main manipulation during angioplasty of the coronary system. The patient involved in this case did not show any contraindication for the treatment with conventional open heart surgery.
