Defining and refining indications for transcatheter pulmonary valve replacement in patients with repaired tetralogy of Fallot: Contributions from anatomical and functional imaging

Transcatheter pulmonary valve replacement (TPVR) is an important treatment option in repaired tetralogy of Fallot (TOF) and right ventricular outflow tract (RVOT) dysfunction. Indications for timing of TPVR are extrapolated from surgical pulmonary valve replacement guidelines, which are themselves controversial as published evidence is scarce and expert opinion therefore prevails. We review current indications for PVR following TOF repair,...
