The study of Branching pattern and variations in the left coronary artery in human heart with a unique case of crossing of coronary arteries- A cadaveric study
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2017, Vol 4, Issue 1
Abstract
Background and Aims: Coronary artery disease is one of the major causes of death worldwide; the incidence of coronary artery disease is increasing today in developing countries, because of sedentary lifestyle, urbanization, hypertension, diabetes mellitus and increased type A personality. The increasing use of diagnostic and therapeutic interventional procedures requires a sound, basic knowledge of the coronary artery pattern. This study was undertaken to know the course, branches and variations in left coronary artery. Materials and Method: Heart specimens were collected from cadavers during routine dissection classes conducted by the department of anatomy and preserved in 5% formalin. Hearts were dissected by underwater dissection method. Course of left coronary artery and its branches were traced carefully. Results: In the present study bifurcation was seen in 66.67% of specimens. Trifurcation in 23.33% of specimens and quadrafurcation in 10% of specimens. Most common termination of left anterior descending artery was wrapping around the apex and terminating in the posterior interventricular sulcus and most common termination of left circumflex artery was between obtutus margin and crux. Conclusion: Variations of coronary arteries are common. A thorough knowledge of coronary arteries will be helpful to the cardiologists and radiologists to predefine the abnormalities by invasive and non-invasive studies.
