Assessment of right ventricular function by treadmill exercise stress cardiovascular magnetic resonance in patients with repaired tetralogy of Fallot
Background Cardiac MR (CMR) is considered the gold standard to assess right ventricular (RV) function in different scenarios, including cases of congenital heart disease. Moreover, an MR-compatible treadmill coupled with Real Time (RT) CMR has been developed for stress testing, and may be an optimal choice in this setting. The aims of this study were to determine the feasibility and accuracy of...
متن کاملProgression of right ventricular dilation in repaired tetralogy of fallot
PURPOSE To evaluate factors associated with rapid rate of progression (ROP) of right ventricular (RV) dilation by cardiac MRI in repaired tetralogy of Fallot (TOF) patients. MATERIALS AND METHODS All patients with repaired TOF with two MRIs were included. RV volumes and function were assessed by MRIs performed on a GE 1.5 Tesla (T) platform. The ROP of RV dilation was calculated as the differ...
متن کاملProgress of right ventricular dilatation in adults with repaired tetralogy of Fallot and free pulmonary regurgitation
Background The time course of progressive dilatation of the right ventricle (RV) in adults with pulmonary regurgitation (PR) late after repair of tetralogy of Fallot (TOF) is poorly characterized. Methods We analysed cardiac MRI data (1.5 T) from 14 adult repaired TOF patients (26 ± 11 years of age) with dilated RVs and known significant PR, on 2 separate visits with a between MRI period of 2...
متن کاملAssessment of ventricular function in adults with repaired Tetralogy of Fallot using myocardial deformation imaging.
AIMS Many patients with repaired Tetralogy of Fallot (ToF) have right ventricular (RV) volume overload due to pulmonary regurgitation (PR). We studied the effect of volume overload on global and regional RV and left ventricular (LV) deformation, and their relationships with conventional diagnostic parameters. METHODS AND RESULTS In this cross-sectional study, 94 prospectively recruited ToF pa...
متن کاملAssessment of intra- and inter-ventricular cardiac dyssynchrony in patients with repaired Tetralogy of Fallot: a cardiac magnetic resonance study
Methods 30 patients with repaired TOF (age 28 ± 16, 46% female) and 17 healthy controls (age 29 ± 7, 12% female) underwent cine CMR. Patients were imaged twice to assess inter-test reproducibility. Circumferential strain vs time curves were generated with a custom feature tracking algorithm for 12 LV and 12 RV segments in 4-7 slices encompassing the ventricles. For each segment, the temporal of...
