Optimal pulmonary vascular resistance index ‘cut-off’ for bi-ventricular congenital heart disease operability

Bi-ventricular congenital heart disease with pulmonary hypertension may be inoperable. Several clinical features suggest operability, but the definitive method for determining operability is the measurement of pulmonary vascular resistance index (PVRI). The "cut-offs" for operability reported in the literature range from 5 to 10.3 Wood Units per m2 (WU·m2). The objective of this study was to identify...
