A roadmap to arrhythmias after transcatheter pulmonary valve replacement in pediatric patients

Abstract

Right ventricular outflow tract (RVOT) and pulmonary valve dysfunction are commonly seen in pediatric patients, particularly those with Tetralogy of Fallot. 1 Most of these patients undergo surgical repair with the expectation that they may require surgical re-intervention to replace a regurgitant pulmonary valve or to relieve RVOT stenosis. 2 The first transcatheter pulmonary valve implantation was performed by Bonhoeffer et al. 3 in early 2000 with a right ventricle-to-pulmonary artery (RV-PA) conduit.
