Key result
MDCT detects a diffuse myocardial bridge missed by conventional coronary angiography in a single RCA.
Why the study?
The clinical and anatomical evaluation of patients with a single coronary artery and myocardial bridge requires precise imaging techniques.
Case Report (n=1)
MDCT provides superior anatomical evaluation compared to conventional angiography for detecting myocardial bridging in patients with anomalous coronary arteries.
MDCT may identify missed bridges in anomalous coronaries; leaves open whether routine use alters management or outcomes.
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.

Shin et al. (2012) conducted a case report in Single right coronary artery with anomalous origin of left anterior descending artery and diffuse myocardial bridge (n=1). Multidetector computed tomography (MDCT) vs. Coronary angiography was evaluated on Detection of myocardial bridge. Multidetector computed tomography successfully detected a diffuse myocardial bridge in a patient with a single right coronary artery that was missed by conventional coronary angiography.
