[Ostial occlusion of the left coronary artery in a female patient with chronic stable angina. The coronary cineangiographic aspect].
The left main coronary artery occlusion is the most dangerous presentation of arteriosclerotic coronary artery disease, often resulting in hemodynamics and electrical instability that ultimately lead to death (fatal acute episodes and/or sudden death). A 47-years-old female with multiple risk factors went on a cardiologic check-up, including coronary angiograms, as a preoperative evaluation of a routine abdominal surgical procedure. The angiograms provided definite information about the coronary vessels including total occlusion of the ostium of the left main coronary artery (LCA) and collateral circulation from the right coronary artery (RCA). The RCA was dominant and normal. The left ventriculogram showed hypertrophy but the left ventricular function was normal. These clinical and angiographic findings were analyzed at a surgical-clinical session and a coronary artery bypass graft operation (myocardial revascularization) was done.
