Background CT coronary angiography (CTCA) is widely used to rule out significant coronary artery disease in patients who present with chest pain. However, in our institution, its use in clinical practice has not been properly audited. Methods We retrospectively studied the results of patients who had undergone a CTCA at our institution over the previous 3 years in terms of indication and outcomes. Results The CTCAs of 659 patients (mean age 51.5+13.8 years; 395 or 59.9% male) were analysed. Chest pain (67.2%) was the main indication for requesting CTCA, with breathlessness (17.6%) and palpitations(11.7%)being the other indications. Of the findings, majority of the patient had right dominance (81.1%) with 9,7% having left dominance and the remainder co-dominant. Of the congenital abnormalities noted, 19 (2.8%) had abnormal origins (RCA 9, circumflex 3), 3 had aneurysms, and 29 (4.4%) had ectatic vessels. 77 patients had evidence of more than 50% stenosis, but 94 patients (14.3%) subsequently had an angiogram. Of these 94 patients, 47 had evidence of significant disease and underwent intervention. Conclusions CTCA is often requested for indications other than chest pain. The use of CTCA resulted in only a small proportion of patients proceeding for invasive coronary angiography and helps in triaging patients better. The incidence of congenital coronary abnormalities in our study was similar to that reported in literature. Conflict of Interest nil
