ABSTRACT
Background: Congenital anomalous origins of the coronary arteries are a rare but well-described cause of myocardial ischemia and sudden death
Objective: To determine the frequency of coronary artery anomalies in adult patients undergoing coronary angiography for ischemic heart disease
Methodology: A total of 493 consecutive patients with diagnosed Ishemic Heart Disease [IHD] visiting Department of Cardiac Catheterization, Ch. Pervaiz Elahi Institute of Cardiology, Multan were included in this cross sectional study from 15[th] June to 15[th] December 2014. Diagnostic coronary angiography was carried out. The outcome variable i.e. coronary anomalies as defined in operational definition were noted on the performa
Results: There were 493 patients. Males were 293 [59.4%] while females were 200 [40.6%]. Mean age of the patients was 54.45 +/- 13.02 years ranging in age from 18 to 70 years. Coronary artery anomaly was identified in 8 [1.6%]. Separate left anterior descending and left circumflex artery was observed in 2 [0.4%], Left circumflex artery arising from right coronary sinus was observed in 1 [0.2%], Right coronary artery arising from left coronary sinus was observed in 2 [0.4%], left coronary artery arising from right coronary sinus was observed in 1[0.2%] while myocardial bridging was observed in 3 [0.6%]. One of the patients with myocardial bridging also has left coronary artery arising from right sinus
Conclusion: Myocardial bridges were the most frequently encountered problem followed by separate origins of LAD and left circumflex and then right coronary artery arising from the left coronary
