Common Coronary Anomalies on MDCT
Keywords:
Coronary artery anomalies, MDCT, high take-offAbstract
Coronary artery anomalies are rare, and the incidence is around 1 to 2% in the general population. Majority of the patients
are asymptomatic and detected while investigating another clinical issue. A few anomalies may be life-threatening due to
the malignant course with potential for ischemia and even sudden death. Multidetector computed tomography (MDCT)
has high accuracy in detecting these anomalies because of volume rendering (VR) and multiplanar reconstruction (MPR).
‘High take-off’, origin of the coronary artery from the opposite or noncoronary cusp with anomalous course and coronary
artery fistula are three most frequent anomalies. MDCT can be a useful screening tool in the study of coronary anomalies.
