Anatomical variations in relation to coronary artery and its branches will help cardiac surgeons for refining imaging techniques and coronary artery bypass grafting. A heart was detected with multiple anomalies of coronary arteries in a cadaver. The anomalies of coronary arteries in terms of origin, number of ostia, courses, and presence of myocardial bridges were described, and related clinical implications were highlighted in the present study. The knowledge of variant anatomy may be of paramount importance to anatomists for variant anatomy and to cardiac surgeon for proper diagnosis and treatment of cardiac ailments including radiologists to refine image interpretation.

Anomalies of the coronary ostia are of great practical significance than those of coronary arterial distribution. High degree of association exists between anomalies of the coronary ostia and other congenital cardiovascular defects. Detailed knowledge and awareness of the anatomical variations in ostia of coronary artery and its major blood vessels may help to overcome potential difficulties in certain cardiosurgical procedures. A cadaveric study in an unsuspected population provides a basis for understanding the normal variants, which may facilitate determination of the prevalence of anomalies and evaluation of the value of screening for such anomalies. METHODS: The study was carried out on 30 embalmed hearts in the department of anatomy SAIMS. Numbers of ostia, position of the ostia within each aortic sinus with reference to the sinutubular [ST] ridge and the upper margin of cusps were noted. The height of the cusps and the coronary ostia were measured from the bottom of the aortic sinuses [nadir] with the help of a digital vernier caliper. Positions of the ostia were also observed with reference to the commissures. RESULTS: The number of Ostia in the various Aortic sinuses ranges from 1to 3. No openings were found in Right Posterior Aortic Sinus. In majority cases the position of Coronary Ostia is above the Upper margin of cusps (95%). In 80% cases the position of Coronary Ostia is below the Sinu-tubular ridge. In 63% cases ostial openings were centrally located. The Left cusps were found to have greater height as compared to Right cusps. The height of Left coronary ostia was at higher level (15.65 mm). CONCLUSION: Variant anatomy of the ostia of the coronary artery, its detailed knowledge and awareness of major blood vessels may help to overcome potential difficulties in certain cardiosurgical procedures.

“…Multiple ostia for both coronaries, however, is not rare and knowledge of ostia anatomical variation is crucial during an aortic root reconstruction and coronary angioplasty. [7,8] In a study by Pejkovic et al, ostia were located 2-10mm inferior to the sinotubular junction in 90% of cases. Additionally, separate conal ostia from the right sinus of Valsalva were found in 33% of cases.…”
