Data are presented as mean ± standard deviation or n (%). LVEDD left ventricular end-diastolic diameter; LVEF, left ventricular ejection fraction; LVESD, left ventricular end-systolic diameter; sPAP, systolic pulmonary artery pressure; TAPSE, tricuspid annular plane systolic excursion. Data are presented with associated p values, with bold values indicating statistical significance at p < 0.05.
