Anomalous origin of the left coronary artery from pulmonary artery mimicking antero-lateral ST-elevation myocardial infarction: a case report.

ABSTRACT:

Background

Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (PA) (ALCAPA) is a rare congenital abnormality. We present a case of an ALCAPA in a 25-year-old man.

Case summary

A 25-year-old male with no past medical history was admitted to our intensive cardiac care unit after sudden cardiac arrest due to ventricular fibrillation and suspected acute coronary syndrome. After being treated with shock by automated external defibrillator, an electrocardiogram (ECG) demonstrated sinus tachycardia with antero-lateral ST-segment elevation. Initial transthoracic echocardiography showed severe and diffuse left ventricular dysfunction and dilatation. Coronary angiography revealed anomalous origin of the LCA from the PA and extensive collateral circulation fro
