TRANSCATHETER VENUS P VALVE IMPLANTATION AT PULMONARY POSITIONPOST TOF REPAIR WITH SEVERE PR- INITIAL CASE IN PAKISTAN

Abstract

After total correction for tetrolgy of fallot (TOF), right ventricle behaves in an unpredictable manner depending on type of right ventricular outflow tract (RVOT) reconstruction and surgical expertise of infundibular muscle resection. We are reporting a 23 years old girl who underwent total correction at two years of age. RVOT was reconstructed with native pericardial patch. Gradually she developed breathlessness and occasional chest pain. Echocardiograghy revealed hugely dilated right ventricle (RV) with gross pulmonary regurgitation and RV dysfunction. Cardiac MRI also calculated right ventricular end systolic volume (RVESV) 57 ml/m2 and right ventricular end diatolic volume (RVEDV) 157ml/m2. We decided to implant transcatheter venus p-valve at pulmonary position. The procedure went successful having competent pulmonary valve and improved RV function. Total fluoro time was 36.4 minutes and total procedural time was two hours. This procedure was done first time in Pakistan with optimal results.
