Key result
Transvascular pulmonary valve implantation significantly reduced peak right ventricular outflow tract gradient from 73.4 mm Hg to 35.3 mm Hg (p<0.001) and restored pulmonary valve competence.
Why the study?
Does transcatheter pulmonary artery valve implantation improve RVOT hemodynamics and right ventricular function in patients with repaired congenital heart disease?

Answers are grounded in this paper and cite their sources.
Transcatheter pulmonary valve implantation with routine pre-stenting is an effective and safe method to restore pulmonary valve competence and reduce RVOT gradient in patients with repaired congenital heart disease.
Background: Transcatheter pulmonary artery valve implantation (TPVI) is a relatively new method of treatment in patients (pts) after repair of congenital heart disease (CHD).

Biernacka et al. (2010) conducted an observational in Right ventricular outflow tract conduit dysfunction (n=17). Transvascular pulmonary valve implantation (TPVI) vs. Baseline was evaluated on Peak right ventricular outflow tract (RVOT) gradient (p=<0.001). Transvascular pulmonary valve implantation significantly reduced peak right ventricular outflow tract gradient from 73.4 mm Hg to 35.3 mm Hg (p<0.001) and restored pulmonary valve competence.
