The apical views are presented with the 2D views on top and the corresponding MPR result on the bottom. The views consisted of the RVF view (A), the apical view with left ventricular outflow tract or apical five-chamber view (B), and the apical view with coronary sinus (C). In all cases, the septal leaflet was seen closest to the septum. The leaflet against the RV free wall could be either the anterior or the posterior leaflet. In the RVF view (A), the leaflet against the RV free wall was almost always the posterior. The A-S combination was seen if the 2D plane intersected with the LV outflow tract (B), while the P-S combination was seen if the 2D plane was near the coronary sinus (C).
