Conditions

There are several factors that influence the successful implantation of TPVR in native RVOT, including RVOT diameter and morphology. We compared these characteristics between TPVR and SPVR groups and sought to identify morphological and dimensional predictors of successful TPVR outcomes.

All

Inclusion criteria

Inclusion criteria: Patients who underwent redo-PVR (TPVR or SPVR) for a native RVOT dysfunction following primary repair of their congenital heart disease were included. The patients required to have data from a cardiac catheterization and cardiac MRI/CTA which completely obtained RVOT /MPA angiography prior to redo-PVR in order to re-evaluate the RVOT morphology and size in this study

Exclusion criteria

Exclusion criteria: Patients who had incomplete obtained data were excluded.
