RV function in adult patients with repaired tetralogy of Fallot: assessment by three-dimensional echocardiography, comparison to CMR findings and relationship to pulmonary artery distensibility
Purpose. The purpose of this study was to examine right ventricular (RV) function by three-dimensional speckle-tracking echocardiography (3DSTE) in patients after correction of tetralogy of Fallot (TF), the accuracy of 3DSTE compared to cardiovascular magnetic resonance (CMR) findings and assess pulmonary arterial (PA) distensibility in order to achieve a more comprehensive understanding of the matching between RV performance and PA load.
