Abstract

This article investigates the impact of residual pulmonary stenosis (rPS) combined with pulmonary regurgitation (PR) on postoperative outcomes after surgical pulmonary valve insertion (SPVI) in patients with repaired tetralogy of Fallot (TOF), focusing on the role of right ventricular ejection fraction (RVEF). In a retrospective multicentre study of 117 patients, those with both rPS and reduced RVEF (rEF) exhibited the highest right ventricular end-diastolic pressure (RVEDP) and the lowest freedom from adverse cardiovascular events, suggesting advanced right ventricular systolic and diastolic dysfunction. The study highlights that reduced RVEF may mask the severity of residual stenosis, potentially delaying surgical intervention and increasing postoperative risks. It concludes that assessing rPS in conjunction with RVEF and RVEDP could improve timing for SPVI and risk stratification in this patient population.
