quantitative assessment of right atrial function by strain imaging in adult patients with totally corrected tetralogy of fallot
conclusions in light of our findings, we concluded that ra function is severely diminished in adult patients with tof. it would play an important role in pathophysiological process of the right sided heart failure in these patients. results the myocardial velocities and deformational indices of ra free wall were significantly compromised in tof patients compared with normal subjects. there was ...
متن کاملQuantifying regional right ventricular function in tetralogy of Fallot.
Right ventricular (RV) function is notoriously difficult to quantify. Patients with tetralogy of Fallot (TOF) have decreased systolic performance. We measure regional RV performance using MRI with 1-dimensional myocardial tissue tagging. By tagging cine-MRI in two views, we measured regional shortening in 12 regions throughout the RV. We image 32 pediatric patients: 21 normal patients and 11 pa...
متن کاملRight ventricular strain in patients with tetralogy of Fallot
Background Left ventricular (LV) circumferential strain shows cardiac dysfunction earlier than ejection fraction. However, measuring right ventricle strain is technically challenging due to the thin RV wall and complex morphology. Also, the predominant RV strain is longitudinal, whereas the predominant LV strain is circumferential. We recently validated a feature tracking algorithm for evaluati...
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 کاملRight atrial area and right ventricular outflow tract akinetic length predict sustained tachyarrhythmia in repaired tetralogy of Fallot
AIMS Repaired tetralogy of Fallot (rtoF) patients are at risk of atrial or ventricular tachyarrhythmia and sudden cardiac death. Risk stratification for arrhythmia remains difficult. We investigated whether cardiac anatomy and function predict arrhythmia. METHODS One-hundred-and-fifty-four adults with rtoF, median age 30.8 (21.9-40.2) years, were studied with a standardised protocol including...
