Evaluation of left and right ventricular (RV) longitudinal systolic function may enhance risk stratification following aortic valve replacement (AVR). The study objective was to evaluate the changes in left and RV longitudinal systolic function and RV–pulmonary artery (RV–PA) coupling from baseline to 30 days and 1 year after AVR.
Left ventricular (LV) longitudinal strain (LS), tricuspid annulus plane systolic excursion (TAPSE), and RV–PA coupling were evaluated in patients from the PARTNER 2A surgical AVR (SAVR) arm (
SAVR but not TAVR was associated with a marked deterioration in RV longitudinal systolic function and RV–PA coupling. Lower TAPSE and RV–PA coupling at 30 days were associated with inferior clinical outcomes at 5 years. In patients with LVEF < 50%, TAVR was associated with superior 5-year outcomes.
