Abstract
Percutaneous pulmonary valve implantation is been increasingly performed for restoring pulmonary competence in appropriately selected patients. How- ever, The currently available valves are not capable of being safely implanted in the majority of patient with outflow tract dysfunction as they cannot accommo- date the larger outflow tract diameters seen in most patients. The Venus P-valve is a new percutaneous pul- monary valve designed specifically for implantation in large (up to 32 mm diameters) native right ventricular outflow tracts. In this report we describe the combined use of a Venus P-valve and Melody transcatheter pul- monary valves in a patient with a dysfunctional native and artificial right ventricular outflow tracts.

Introduction
Percutaneous pulmonary valve implantation using the Melody® (Medtronic, Minneapolis, MN, USA) (CE Marked 2006) and the Edwards Sapien XT (Edwards
Lifesciences, Irvine, CA, USA, CE Marked 2017) valves is currently a widely accepted alternative to surgery for the management of selected patients with dys- functional right ventricular outflow tract conduits or homografts [1]. However, only < 20% of patients fol- lowing tetralogy Fallot repair are candidates for these two valves as they cannot be used in large patched right ventricular outflow tracts (RVOTs) [1]. The Venus P-valve (Venus Medtech, Shanghai, China) is a new self-expanding tri-leaflet porcine pericardial tissue percutaneous pulmonary valve designed specifically for implantation in large (up to 32 mm diameters) na- tive RVOT [2-4]. Early clinical experience with implan- tations in humans has shown its safety and satisfacto- ry early results. [2-4] In this short communication, we report the first-in-man use of Venus P-valve and Mel- ody® transcatheter valves on separate occasions in a patient with dysfunctional native and artificial RVOT.
Case presentation
A 21 years male with tetralogy of Fallot underwent surgical correction at the age of 24 months. Due to the presence of an anomalous course of anterior de- scending artery across the RVOT an initial attempt was made to relieve the sub-pulmonary obstruction
