Abstract

Anomalous coronary arteries with an inter-arterial course are associated with sudden cardiac death. We reported a study comparing the accuracy of fluoroscopic coronary angiography (FCA) with that of multi-slice computed tomography (MSCT) coronary angiography in determining the proximal course of anomalous coronary arteries. Twelve patients with thirteen anomalous coronary arteries had both FCA and MSCT coronary angiography were included in this study. Twelve cardiologists individually reviewed FCAs of anomalous coronary arteries and determined the proximal course of anomalous coronary arteries as retro-aortic, inter-arterial or ante-pulmonary. Their diagnoses were compared with MSCT coronary angiography which was regarded as the reference standard in this study. On MSCT coronary angiography, there were six anomalous left circumflex arteries with a retro-aortic course, five anomalous right coronary arteries and one anomalous left anterior descending artery with inter-arterial courses, and a single anomalous left main artery with an ante-pulmonary course. The percentage of correct diagnosis made by 12 cardiologists based on FCA findings was 93/156 or 60%. None of the cardiologists was correct in determining the proximal course of all anomalous coronary arteries. The median number of anomalous coronary arteries with their proximal courses correctly identified by the cardiologists was 7.5 (range 3-12). In conclusion, FCA was limited in delineating the proximal course of anomalous coronary arteries in comparison with MSCT coronary angiography. Crown
