Risk stratification and clinical outcomes after surgical pulmonary valve replacement

To determine if RV volume was predictive of survival and cardiovascular adverse event (CAE) after pulmonary valve replacement (PVR).We reviewed the MACHD (Mayo Adult Congenital Heart Disease) database for patients with tetralogy of Fallot (TOF) undergoing PVR, 2000-2015. The patients were divided into quartiles based on RV end-diastolic volume index (RVEDVI); those in the lowest quartile (Group A, n = 46) and the top quartile (Group B, n = 42)...
