Figure 4 Anatomical Analysis: Left Coronary Ostium and Leaflet Length
Coronary ostium occlusion may occur after percutaneous aortic valve replacement. Therefore, it is important to assess the relation between the ostia of the coronary arteries and the coronary leaflet length. With the use of a coronal view, the distance between the annulus and the ostia of the coronary arteries, and the length of the coronary leaflets were assessed. This figure demonstrates the measurements of the distance between the annulus and the ostium of the left coronary artery, and the measurement of the left coronary leaflet length.
