Single right coronary artery giving off anomalous origin of left anterior descending artery with diffuse myocardial bridge: the role of computed tomography scan

Abstract

A 58-year-old woman who presented with resting chest pain underwent coronary angiography and multidetector computed tomography (MDCT), with detection of a single right coronary artery giving off an anomalous origin of the left anterior descending artery, subpulmonic type with diffuse myocardial bridge. The myocardial bridge was detected by MDCT, not by coronary angiography. Our findings suggest that MDCT has an important role in the more precise evaluation of clinical and anatomical information in patients with a single coronary artery.
