ABSTRACT:<\/strong><\/p>\n

Aim:<\/strong> This current study is done to throw light upon the, distribution and termination of right coronary artery and left anterior descending branch of left coronary artery and to correlate the clinical significance of the variations observed<\/p>\n

Materials and methods:<\/strong> 30 human hearts from the embalmed cadavers from Department of Anatomy, Great Eastern Medical School were collected during routine dissection. The heart is taken out after incising the fibrous pericardium and great vessels .The course of right and left coronary arteries were traced from the Ostia. The specimens were duly numbered, preserved in 5% formaldehyde solution. Photographs of each specimen were taken by digital camera and the arterial pattern is coloured red digitally and labeled.<\/p>\n

Results<\/strong>: In the present study the right coronary artery terminates at crux or beyond the crux in 57%, before crux in 23% and right border in 13%. Left anterior descending artery terminates beyond apex in the lower 1\/3rd of the inter-ventricular groove in 87% and at the apex in 13%.<\/p>\n

Conclusion<\/strong>: Right and left coronary arteries showed significant variation in their mode of termination. Better anatomical knowledge about the branches of coronary artery and its variation is essential for cardiologists and interpretation of coronary angiograms by radiologist.<\/p>\n

Key words<\/strong>: Right Coronary Artery, Left Coronary Artery , Left Anterior Descending Artery, Crux Of The Heart.<\/p>\n
