ABSTRACT
The right and left coronary ostia are located in relation with the sinus of Valsalva. The coronary ostia are located close to the aortic root, which is an important area for interventional cardiologists and radiologists. This study encompasses the topography, morphology and morphometry of the coronary Ostia. 90 cadaver heart specimens fixed in 10% formalin were dissected. Shape and location of the coronary ostia was determined. The diameter of the ostium and distance from the base of the cusp up to the ostium was measured with the help of a measuring scale. 76.6% of Right coronary ostia (RCO) and 73.3% of Left coronary ostia (LCO) were horizontally oval in shape. 16% of RCO and 23% LCO were circular and 7% of RCO and 10% of LCO were vertically oval in shape. The mean diameter of RCO & LCO was 2.5±1 mm and 2.8±1 mm respectively. 56.6% of Right coronary ostia and 52.2% of Left coronary ostia were located in the central (middle 1/3rd) position of the cusp. The ostia were located at a distance of 5-18 mm from the base of the cusp. The average diameter was 2.5 mm. The most common location was sinotubular and central, and the most common shape was horizontally oval. Occasionally, more than one ostium was seen in the right coronary sinus. Study of the topography, morphology and morphometry of coronary ostia is essential for cardiac interventional procedures done for diagnostic and therapeutic purposes
