STUDY OF CLINICAL PROFILE, INCIDENCE AND PATTERN OF CONGENITAL CORONARY ARTERY ANOMALIES IN ADULTS UNDERGOING CORONARY ANGIOGRAPHY

Objectives: To study the clinical profile, incidence, and pattern of congenital coronary artery anomalies (CAAs) in adults undergoing coronary angiography. Methods: Coronary angiogramof 3600 patients done between September 2017 and September 2021 were reviewed for the presence of CAAs. Results: Angiography data of 3600 patients done between September 2017 to September 2021 was reviewed in the present study and 88 patients were found to have CAAs giving a prevalence of 2.44%. Mean age of patients was found to be 56.86±11.49 years (range 24-75 years). Among these, the anomalous origin and course of the coronaries were the most common anomaly seen in 73 (2.02%) patients, followed by intrinsic anomalies of the coronary arterial system in 13 (0.36%) patients , followed by anomalous coronary termination in 01 patient (0.03%) and single coronary artery 01 patient (0.03%). Conclusion: The prevalence of congenital coronary anomalies in the study was found to be 2.44%. and commonest anomaly was that of origin and courseof the vessels (88%). Though the prevalence of CAAs in this study was similar to that in previous studies, the pattern of anomalies was slightly different from previous studies.
