Abstract Background: The right ventricular (RV) contractile reserve is a measure of the dynamic function of
the RV and is a sensitive indicator of volume load. This can be measured noninvasively using the
tricuspid annular plane systolic excursion (TAPSE) during exercise. We studied the RV contractile
reserve of patients after tetralogy of Fallot (TOF) repair with varying degree of RV dilation and pulmonary regurgitation (PR), and compared them to a control group.
Methods: Twenty-six patients who had undergone TOF repair (mean age 29 ± 10 years) were
identified and stratified into three group based on the presence and… More >
