Comparison between the Early outcome of Fallot Repair with Preservation of the Pulmonary Valve Annulus versus Transannular Patch Repair

Abstract

ransannular patch repair has dramatically reduced death in TOF. However, the paradigm for surgical repair of TOF has shifted. A prior strategy focused exclusively on relief of PS has changed into one that additionally aims to avoid the now known long-term deleterious consequences of pulmonary regurgitation. Consequently, many surgeons now favor valve-sparing approaches and have extended the boundaries of repair toward PV z scores that have previously been considered too small to spare. An optimal repair would restore normal RVOT anatomy and physiology, a PV which functions normally without PS.
