Anomalous origin of the left circumflex artery from right sinus of Valsalva: a rare case but with great clinical relevance
Cor et Vasa(2023)
Abstract
Anomalous origin of coronary artery (CA) is rare and does not generally lead to myocardial infarction. We re-port a case of a 61-year-old man presented with paroxysmal supraventricular tachycardia and atypical chest pain. After arrhythmia subsided, ECG showed T wave abnormalities and transient cardiac enzymes were found to be elevated. Coronary angiography demostrated an anomalous origin of the left circumflex artery (LCx) from the right sinus of Valsalva but no obstructive atherosclerotic coronary lesions. The possible rela-tion between the congenital coronary anomaly and the clinical manifestations of the patient is discussed.
