A 70° curvature is observed in post-Right Ventricular Outflow Tract Reconstruction (RVOTR) patients leading to a malfunctional  tri-leaflet biologic homograft. We demonsrate a novel polytetrafluroethylene (PTFE) bi-valve conduit for optimal performance in a 70° post RVOTR curvature setting. PTFE is a bio-inert material superior to conventional biologic options with minimal risk of calcium deposition, thrombosis, and immune based rejection. 

Pathophysiology Congenital pulmonary artery (PA) stenosis occurs either in isolation or associated with other congenital heart diseases such as Tetralogy of Fallot, Truncus Arterios, pulmonary atresia and Transposition of Great Vessels Advanced Cardiac MRI Advanced cardiovascular magneitc resonace imaging (cMRI) and magenitc resonance angiography (MRA) techniques with 3-dimensional and 4-dimentional image reconstructions can precisely quantify blood flow, velocity, valvular insufficiency and cardiac function required for timely patient management Advanced Treatment| We discuss advanced treatment startegies of RVOTR and clinical advantages of PTFE bi-valved conduit compared to tri-leaflet homograft Future directions Prospective cMRI study in patients undergoing RVOTR at our institution will establish future treatment standards
