Background
Coronary artery anomalies refer to a comprehensive group of conditions that describe congenital variations in the anatomical distribution of the coronary arteries beyond that of the accepted norm. Their prevalence is up to 1.3% in adults[1], yet in many cases impose an increased risk of mortality, and thus are critical to recognise and diagnose accurately.
ECG-gated iodinated contrast computed tomography coronary angiography has an important imaging role in coronary artery disease in symptomatic patients but is also employed increasingly for suspected coronary artery anomalies. The recent surge of high-resolution CTCA utilisation has lead to an increased number of incidental and purposefully diagnosed coronary artery anomalies, which can be exemplified in high detail. CTCA confers the benefit of a non-invasive 3-dimensional delineation of anomalies in any anatomical plane when compared to invasive coronary angiography and is also found to be superior in detection rate of coronary artery anomalies[2].
The last 5 years of CTCA studies in a tertiary centre were retrospectively reviewed for coronary anomalies. A variety of common and rarer anomalous coronary cases were selected for presentation and discussion in this poster presentation.
