Abstract
In 1964, Rastelli and colleagues1 inserted a nonvalved pericardial tube as the first right ventricle to pulmonary artery (RV-PA) conduit. As is common with technical advances in any subspecialty, the evolution of how best to reconstruct the right ventricular outflow tract or which conduit is best suited to create the RV-PA connection remains ill-defined. Freedom from reintervention has historically been the defining quantitative metric of success. The ideal option for the conduit would have the characteristics of long-term patency and valve function, availability in a wide range of sizes, good handling, growth potential, low cost, low infectious potential, and no need for anticoagulation.
