title: [Chronic total occlusion of the left main coronary artery].
abstract: Total chronic occlusion of the left main coronary artery is a rare angiographic finding in a catheterization laboratory. After reviewing the coronary angiographies performed in our laboratory between 1986 to 1995, we found a prevalence of 0.04%. These patients presented unspecific symptoms similar to other kinds of coronary artery disease. In all cases, the right coronary artery was dominant with extensive collateral circulation to the left coronary artery. Ventricular function was normal in 50% of the cases. Probably, in these unusual cases, the best therapeutic approach is surgical revascularization.
