Data are mean ± SD. Before-after changes are summarized as means (95% confidence intervals [CI]) or medians (95% CI). *Matched data for change from pre-procedure to before discharge. ^†Matched data for change from before discharge to three months of follow-up
Abbreviations: LV, left ventricular; RV, right ventricular; sPAP, systolic pulmonary artery pressure; TAPSE, tricuspid annular plane excursion
