Transgastric RV inflow views for tricuspid apparatus (Figure 8)
Transgastric views for right heart give details about moderator band, papillary muscles for anterior and posterior leaflets (RV inlet view), and the only 2D view for simultaneous visualization of all 3 tricuspid leaflets (RV basal view). On CT simulation, we firstly move the MPR crosshairs into the gastric cardia and then rotate the axial MPR line clockwise toward the aortic valve. Next, we simulate “turn to the right” by rotating the sagittal MPR line clockwise on the axial MPR plane to cross the RV. Finally, we rotate the axial MPR line on the coronal MPR plane to produce the RV in-out view and the short axis view of tricuspid leaflets.
Examples of left atrial appendage, short-axis view of aortic valve, and bicaval view of interatrial septum are illustrated in Figure 9.
