Myocardial infarction with non‐obstructive disease and anomalous coronary origin: look for the common in the uncommon. (9th July 2022) - Disabato, Gindomenico
Abstract: Management of congenital coronary artery anomalies (CAA) is not standardized due to the variety of conditions included and their rare prevalence. Detection of CAA during myocardial infarction with non‐obstructive coronary arteries (MINOCA) may induce clinicians to address the patient for surgery as CAA is not included in any algorithm 1, 2 for the management of MINOCA and American Association for Thoracic Surgery evidence‐based guidelines suggest surgical repair for patients with anomalous aortic origin of a coronary artery and symptoms compatible with myocardial ischaemia. 3 We present the case of a 35‐year‐old man with an anomalous origin of left coronary artery from right Valsalva sinus with pre‐pulmonic course detected during urgent coronary angiography for suspected myocardial infarction. Stress cardiac magnetic resonance did not show signs of ischaemia at high‐dose dobutamine but did reveal a recent myocarditis. This clinical case highlights the need for accurate risk stratification in CAA especially when confounding clinical scenarios co‐exist.
