Right ventricular free wall strain predicts quality of life in repaired tetralogy of Fallot

چکیده
Methods Fifty-nine patients with rTOF (median age 28 years, range 15-69) underwent cardiovascular magnetic resonance (CMR) from 2008-2009 and completed the Short Form 36 (a validated quality of life assessment). A midventricular short-axis slice was analyzed for left ventricular global circumferential strain (LVGCS) with feature tracking software (TomTec, Unterschleissheim, Germany). A four-chamber slice was analyzed for left ventricular longitudinal strain (LVGLS), and right ventricular longitudinal strain (RVLS), using the three segments of the right ventricular free wall. A subset of 30 patients was re-analyzed for intraobserver and interobserver variability. The physical component summary (PCS) and subscales of physical functioning (PF), role-physical (RP) and general health (GH) were chosen for analysis, and age-adjusted z-score ≤-1 was considered a clinically significant decreased quality of life.

Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

BACKGROUND The aim of the present study was to assess the impact of pulmonary regurgitation (PR) and right ventricle (RV) volume on left ventricle (LV) longitudinal strain (LS) in patients with surgically repaired tetralogy of Fallot (r-TOF). METHODS AND RESULTS The study subjects were 32 adolescent asymptomatic r-TOF subjects and 30 adolescent healthy controls. Two-dimensional (2-D) and 3-di...

Results RV function measured by CMR was negatively correlated with peak systolic strain of mid RV free wall (P=0.038, Pearson r=-0.357) and also negatively correlated to both mean of strain (P=0.028, Pearson r=-0.376) and SR (P=0.035, Spearman’s rho=-0.362) of basal , mid and apical segments of RV. Conclusions Overall, in the assessment of RV function , echocardiographic measurement of strain a...
متن کاملLeft ventricular longitudinal function predicts life-threatening ventricular arrhythmia and death in adults with repaired tetralogy of fallot.
BACKGROUND Sudden cardiac death and life-threatening ventricular arrhythmia remain a concern in adult patients with repaired tetralogy of Fallot. Longitudinal left ventricular (LV) function is sensitive in detecting early myocardial damage and may have prognostic implications in this setting. METHODS AND RESULTS We included 413 tetralogy of Fallot patients (age, 36 ± 13 years; QRS duration, 1...
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...
