Introduction :
Heart diseases rank as the third leading cause of death in Hong Kong. Many of the causes are contributed by coronary artery anomalies(CAA). CAAs describe the abnormalities of coronary arteries in their number, origin, course, structure or termination. Though the occurrence of these anomalies in adult is around 0.2%-1.3%, patients can be asymptomatic or without sufficient symptoms to be alerted. Early and accurate diagnosis of coronary condition helps in saving life. Computed Tomography Coronary Angiogram(CTCA) is regarded as a predominant approach in preliminary investigation of coronary artery condition. It is vital for healthcare practitioners to spot any anomaly they may encounter.
Objectives :
(1) To demonstrate the findings of coronary artery anomalies from CTCA done in North District Hospital(NDH); (2) To enhance healthcare practitioners’ awareness on rare coronary artery conditions.
Methodology :
It is a retrospective study of CTCA done from 2008 to 2018 in NDH. All scans were performed on two 64-slice CT scanners (GE Medical System, Lightspeed VCT, 64 x 0.625mm and Siemens SOMATOM Definition AS), under electrocardiographic (ECG)-gated. Contrast medium (omnipaque 350) was injected into venous system at 5ml/s with saline chase. The findings were categorized and images being processed with Siemens Syngo.via platform.
Result & Outcome :
424 CTCAs were done on average annually in NDH. Rare coronary artery anomalies were identified, including abnormal origin of vessel, hypoplasia, ectopic ostium, fistulae, myocardial bridging, tortuous enlarged vessel and aneurysm. CTCA is a useful tool to identify coronary artery conditions.
