*In this patient AVSD was present and therefore no separate MV/TV annulus measurements could be performed. n.a. Data quality did not allow for measurements of the TV. BVR, Biventricular repair; DORV, Double outlet right ventricle; LV, Left ventricular; MV, Mitral valve; RV, Right ventricular; TV, Tricuspid valve; UVP, Univentricular palliation; VSD, Ventricular septal defect.
