A CROSS SECTIONAL STUDY OF CORONARY ARTERY ANOMALIES IN CORONARY ANGIOGRAPHY PATIENTS

Abstract

Background: Coronary Artery Anomalies (CAAs) presenting in adulthood is rare and associated with adverse cardiac events, including sudden cardiac death. CAA is the second most common cause of Sudden Cardiac Death (SCD) in young athletes. Invasive coronary angiography (ICA) is a ideal diagnostic modality for CAAs.

Aim: To evaluate the incidence and pattern of coronary artery anomalies in patients undergoing Invasive coronary angiography (ICA).

Methods: This was a descriptive study design, enrolled 390 patients who underwent invasive coronary angiography during the study period. Ccoronary artery anatomy was evaluated for identification of coronary anomalies to predefined criteria (origin, course and termination) according to international recommendations.

Results: Out of total most of the participants were 50-60 years age group. Majority of the patients were right dominance (77%), mean value of RCA variance is 75 and the LCA variance 13.75. Incidence of coronary artery anomalies was 3.33% (13/390), “Anomalous origin RCA from left coronary sinus and Anomalous origin LCX from right coronary sinus” were the common anomalies found in our study

Conclusions: Proper knowledge of the anomalies and their clinical significance is highly important in planning treatment and easing hardships of cardiologists in dealing with them
