چکیده
Abstract : Intercoronary communication or coronary arcade is a rare congenital coronary artery anomaly in which there is an open-ended circulation with unidirectional or bidirectional blood flow between two coronary arteries. A 85-year-old woman was admitted to the emergency service with typical chest pain. There was no evidence of transmural myocardial infarction in the results of electrocardography and echocardiography. An intercoronary connection between the left anterior descending artery (LAD) and the right coronary artery (RCA) with an obstructive lesion was detected on coronary angiography. This is a very rare coronary anomaly, only two cases of intercoronary communication between LAD and RCA with an obstructive lesion were found in the literature. The potential cardioprotective role of this entity against atherosclerotic coronary artery disease is discussed in this case report.
