Cine CMR and pulmonary artery flow imaging for depiction of left ventricular (LV) “D-shape” pattern and systolic notching. A, B Systolic still frame of cine short axis view at baseline (A). Systolic flattening of the interventricular septum (“D-shape”) indicated substantial pressure overload of the right ventricle (RV) in the presence of three high-grade ostial PV stenoses. Distinct systolic notching of pulmonary flow curve was present (B). C, D One day after successful stenting of all three PV stenoses, complete reversibility of LV “D-shape” (C) and abolishment of the systolic notch of the pulmonary artery flow curve (D) were noted (Additional file 1: video file 1)
