Longitudinal Validation of the Diastolic to Systolic Time-Velocity Integral Ratio as a Doppler Derived Measure of Pulmonary Regurgitation in Patients With Repaired Tetralogy of Fallot

摘要

BackgroundPulmonary regurgitation (PR) is a common residual lesion and major determinant of outcome following surgical repair for tetralogy of Fallot (TOF). We sought to longitudinally study a previously described echocardiographic index as a correlate of PR measured by cardiac magnetic resonance imaging (CMR).
