A study of coronary artery variations in patients undergoing invasive coronary angiography

Abstract

Background: Invasive coronary Angiography (ICA) is a readily available invasive imaging modality that provides high-resolution anatomical information of the coronary arteries. Studies of coronary artery dominance and variants may helpful for management of coronary artery diseases. Aim: The aim of this study was to evaluate the prevalence of coronary artery dominance and variation in patients undergoing invasive coronary angiography. Methods: This was a descriptive research study design.  20-90 years age group patients undergoing invasive coronary angiography were enrolled in our study. Wide ranges of data were collected as well as evaluation of medical reports in order to distinguish perception over this “Coronary Artery Variations & Anomalies” and prevalence in this country context.  In all patients in which a coronary anomaly, origin, course and/or termination of the coronary arteries had been originally reported. Results: A total of 390 patients undergoing coronary angiography were evaluated for coronary artery variations and anomalies. Majority of the patients (32%) were 50-60 year age group. Most of the patients (77%) had right dominant circulation. Ramus intermedius was the common anatomical variant found in 13.4% cases. Conclusions: ICA is a first line method for detecting coronary artery dominance, variation and anomalies, lead to helping in diagnosing and management of coronary artery diseases.
