Abstract
Understanding the variations in coronary artery anatomy is crucial for effective diagnosis and treatment in cardiology and cardiac surgery. Variations can impact surgical outcomes and diagnostic accuracy, necessitating a thorough investigation of these anatomical differences. This study aims to investigate the branching patterns and lengths of the coronary arteries in adult human cadavers, focusing on identifying variations and anomalies. A total of 35 human cadaveric hearts were dissected and examined. The origins, lengths, and branching patterns of the Right Coronary Artery (RCA) and Left Coronary Artery (LCA) were documented. Statistical analysis was conducted to determine the prevalence and significance of observed variations. Variations were observed in 5 out of 35 hearts (14.29%). Trifurcation of the LCA was noted in 4 hearts (11.43%), and left coronary dominance was observed in 1 heart (2.86%). An abnormal RCA length of 18.6 cm was found in 1 heart (2.86%). The RCA consistently arose from the anterior aortic sinus, and the LCA from the left posterior aortic sinus. The RCA length ranged from 6.5‐13 cm in 34 hearts (97%), with an average length of 9.76±2.114 cm. The LCA length varied from 3‐12 mm, with an average length of 6.8±2.069 mm. The LAD terminated at the apex in 71% of hearts and in the posterior interventricular groove in 29% of hearts. This study highlights significant variations in the coronary artery anatomy, which are essential for improving surgical and diagnostic practices in cardiology. Understanding these variations can lead to better clinical outcomes and patient care.
