Figure 5 Anatomical Analysis: Distance Between Left Coronary Ostium and Leaflet Tip
For percutaneous aortic valve replacement, it is important to assess the distance between the ostia of the coronary arteries and the coronary leaflets, because this may determine the risk of coronary occlusion. On the coronal view, the distance between the tip of the left coronary leaflet and the ostium of the left coronary artery was assessed in diastole and systole.
