Left: Schematics of the velocity field at the VC acquired during systole with continuous Doppler (1D encoded velocity value, top) and 4D flow CMR (3D encoded two-dimensional velocity field, bottom). Right: Definition of the anatomical regions to compute the RPD from the LVOT (Plane 1) to the VC (Plane 2). Two other anatomical regions are defined for the Supplemental Material B, the ascending aorta (AA) from the VC to the brachiocephalic artery (Plane 3), and the descending aorta (DA) from the left subclavian artery (Plane 4) to a plane at the same height of the aortic valve plane (Plane 5).
