Abstract
Catheter-induced coronary artery dissection and occlusion is a rare but serious complication of diagnostic cardiac angiography. A 50 year-old man presented with unstable angina. ECG, exceptional of bradycardia, was normal (57 beat/min). Selective coronary angiography demonstrated 98% narrowing in the mid-portion of the left anterior descending coronary artery (LAD). During the right coronary angiography, following catheter manipulation in the vicinity of the aortic valve, the patient complained of severe chest discomfort, and he had electrocardiographic evidence of acute inferior wall myocardial infarction. Right coronary artery (RCA) was free of the significant obstruction, and it was observed to be having a dominant artery with a spiral dissection (NHLBI Grade IV) located between ostium and the proximal portion of the posterior descending and posterolateral artery bifurcation. The patient was immediately operated with off-pump coronary artery bypass surgery. Consequently, iatrogenic right coronary dissection that is a very rare condition as a cause of myocardial infarction, is discussed in this case report.
