  Figure 3. Cardiac Magnetic Resonance Imaging Cardiac magnetic resonance demonstrating severely enlarged right ventricle (right ventricular end-diastolic volume index: 174 mL/m2) and moderately reduced systolic function (RVEF: 37%), aneurysmal right ventricular outflow tract patch measuring 4.0 cm, severe pulmonary regurgitation (RF: 40%) and severe tricuspid regurgitation, and a restrictive residual VSD (7 × 5 mm, Qp/Qs: 1.5). RF = regurgitant fraction; RVEF = right ventricular ejection fraction; VSD = ventricular septal defect.

  Figure 4. Invasive Hemodynamics Preprocedural (before transcatheter pulmonary valve replacement) invasive hemodynamics with elevated right atrium and ventricle pressures, and wedge and left ventricle end-diastolic pressure gradient due to mitral valve patient-prosthesis mismatch. Normal right atrial pressure <8 mm Hg and right ventricle pressure <24 mm Hg.
