Anomalous Coronary Artery Presenting with S-T Elevation Myocardial Infarction: A Case Report

Abstract

Background: Coronary artery anomalies are very rare congenital conditions. Rarely occurring but potentially fatal abnormalities of the coronary vasculature, abnormalities of the coronary arteries can cause significant cardiac events such as myocardial ischemia (S-T Segment elevation MI) and cardiac arrest. Case Presentation: We are presenting a case of a 60 years old hypertensive female patient who presented with ST-segment elevation in all precordial leads. Management & Results: On angiography, a giant right coronary artery was seen, and no Left coronary artery origin was not appreciated. Hence, Multidimensional CT angiography was done that showed dilated and ectatic left main coronary artery circulation originating from the pulmonary artery just above the pulmonary valve. The patient was declared a high-risk surgical candidate, was advised medical therapy, including beta blockers, dual antiplatelet, and antihyperlipidemic medications, and was advised to restrict physical activity. Conclusion: The rare presentation of an aberrant coronary artery is myocardial infarction with ST-segment elevation, and it might be difficult for doctors and cardiologists to determine the true reason without intervention. To optimize the care of these patients, traditional CAA and MDCT must be integrated with the clinical presentation of the patients.
