Incidence of Coronary Artery Anomalies among Patients Undergoing Coronary Angiography and its Relevance to Appropriate Choice of Coronary Catheter Selection - A Tertiary Care Center Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 5
Abstract
Background: Coronary artery anomalies (CAA) are anatomical variations in coronary vessels associated with various symptoms such as angina, dyspnea on exertion, myocardial infarction (MI), and ventricular tachycardia. Primary congenital anomalies are rare. Lack of suspicion for these rare anomalies is a reason for the delay in proper management. Aim: The aim of this study is to estimate the incidence of CAA. Materials and Methods: This was a prospective, observational study conducted in Government Rajaji Hospital, Chennai for 1 year in patients undergoing coronary angiography. Results: Incidence of coronary anomaly was 2.06% (32 cases) among 1547 patients. Common anomalies found were the anomalous origin of right coronary artery (RCA) from left coronary sinus (LCS) seen in 0.078% (12 cases), separate origin of left anterior descending (LAD), and left coronary artery from LCS is 0.71% (11 cases). Clinical presentation was acute segment elevation MI in 1.55 (24 cases), chronic stable angina in 0.13% 2 (cases), and unstable angina in 0.06% (1 case). In most cases, coronaries were cannulated with routine Judkins right (JR) and Judkins left (JL) catheters. Percutaneous coronary intervention was done in 7 anomalous coronary artery patients. Conclusion: Incidence of coronary anomalies in patients undergoing angiography in our study was 2.06%. The most common anomaly found was anomalous origin of RCA from LCS followed by separate origin of LAD and left circumflex artery. For selective cannulation and intervention routine, JR and JL catheter can be used in most of the patients.
