Abstract :

Background –Knowledge of coronary ostial morphology is of importance for interventional cardiologists to plan their diagnostic & therapeutic procedures. Objective –To observe coronary ostia, in relation to location, sinutubular junction, the bottom, anterior and posterior ends of the cusp, along with the angle of origin of coronary arteries with the proximal length in orthogonal arteries. Results– 67right&65 left ostia were below the sinutubular junction. The mean distance from the cusp was 13.5 mm, 12.73 mm and 12.26 mm when the ostia was located either above, at or below the STJ. The average angle of origin of the coronary artery was 53.64° on the right and 56.31° on the left. Conclusion – There were significant differences with regard to distance of ostia from cusp, angle of origination and the distance between the ostia and the posterior ends of the cusp.
