Superdominant Right Coronary Artery with Absence of Left Circumflex and Anomalous Origin of the Left Anterior Descending Coronary from the Right Sinus: An Unheard Coronary Anomaly Circulation

Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Most of them are discovered as incidental findings during coronary angiographic studies or at autopsies. We present herein the case of a 70-year-old man with symptomatic severe aortic valvar stenosis whose preoperative coronary angiogram revealed a so far unreported coronary anomaly circulation pattern.

Anomalous Coronary

AbstractMyocarditis and coronary artery anomalies are both potentially life-threatening aetiologies of cardiac chest pain in children. We present a case of a young man presenting with non-exertional chest pain and subsequently found to have an anomalous origin of the right coronary artery from the left coronary sinus with an interarterial course in addition to a diagnosis of myocarditis. The patient subsequently was able to undergo surgical correction of his anomalous coronary to mitigate the risk of sudden cardiac death.

Congenital coronary artery anomalies, including anomalous origin of a coronary artery, can manifest as life-threatening conditions, such as myocardial infarction or arrhythmia, and may even lead to sudden death associated with specific congenital anatomical features. Such arteries can also develop atherosclerotic lesions. This report describes the case of a 75-year-old man who was admitted to our hospital due to exertional dyspnea. The right coronary artery was found to originate from the left coronary sinus and exhibit tight stenosis due to atherosclerosis, causing effort angina pectoris. This case highlights the fact that coronary artery anomalies can cause angina pectoris via both atherosclerotic and nonatherosclerotic effects, and successful revascularization was achieved noninvasively via percutaneous coronary angioplasty.
