Multidetector Computed Tomography Evaluation of Congenital Coronary Anomalies: A Pictorial Essay

The purpose of this pictorial essay is to review the Multi-detector Computed Tomography (MDCT) coronary angiography appearance of congenital coronary anomalies [CCA]. CCA are uncommon and most of them are diagnosed incidentally during conventional coronary angiography or MDCT angiography. CCA might also be classified as haemodynamically significant or insignificant. Chest discomfort, dyspnoea, palpitations, syncope, cardiomyopathy, arrhythmia, infarction and sudden cardiac death are examples of clinical symptoms. Even though CCA are not prevalent, they should be thoroughly examined because they are the second most common cause of sudden cardiac death in young athletes. Familiarity with atypical anatomy and their clinical presentation may facilitate appropriate diagnosis and management. This will be of immense help to the clinician planning interventional procedures like stenting, balloon dilatation, or graft surgery particularly when there are secondary changes of calcification, plaque formation and stenosis. Axial sections, multiplanar reconstructions, virtual angioscopy, and 3D volume-rendered images should aid in the detection and improve the interpretation of such anomalies, which can be of immense help to the clinician planning interventional procedures.
