Multivariable assessment of the right ventricle by echocardiography in patients with repaired tetralogy of Fallot undergoing pulmonary valve replacement: A comparative study with magnetic resonance imaging

Summary Background Evaluation of the right ventricle (RV) using transthoracic echocardiography is challenging in patients with repaired tetralogy of Fallot (rTOF). Aims To evaluate the accuracy of conventional echocardiographic variables and real-time three-dimensional echocardiography (RT3DE) in as...

Description
Summary:Summary Background Evaluation of the right ventricle (RV) using transthoracic echocardiography is challenging in patients with repaired tetralogy of Fallot (rTOF). Aims To evaluate the accuracy of conventional echocardiographic variables and real-time three-dimensional echocardiography (RT3DE) in assessing right ventricular (RV) volumes and function compared with magnetic resonance imaging (MRI), in adult patients with rTOF and referred for pulmonary valve replacement (PVR). Methods Complete echocardiography was performed on 26 consecutive patients referred for PVR, before and 1 year after surgery. All variables were compared with MRI. Results Correlations between conventional variables and MRI were absent or poor when assessing RV ejection fraction (RVEF), except for fractional area of change (FAC; r = 0.70, P < 0.01 before PVR; r = 0.68, P < 0.01 after PVR) and RT3DE ( r = 0.96, P < 0.01 before PVR; r = 0.98, P < 0.01 after PVR). The RV volume correlation between RT3DE and MRI was excellent before and after surgery for RV end-diastolic volume ( r = 0.88, P < 0.01 and r = 0.91, P < 0.01, respectively) and RV end-systolic volume ( r = 0.92, P < 0.01 and r = 0.95, P < 0.01, respectively). The accuracy of these indices, as a diagnostic test for impaired RV (
