About this trial
The main goal of this study is to determine the effects of combination medical therapy (Riociguat and Macitentan) and balloon pulmonary angioplasty (BPA) on hemodynamics and right ventricular (RV) function (including advanced assessments of RV-pulmonary artery (PA) coupling from invasive hemodynamics) in participants with inoperable or post-PTE residual CTEPH.

Trial outcomes
Primary outcomes
Change in end-systolic elastance (Ees) divided by arterial elastance (Ea) (Ees/Ea) at three time points: Baseline, Timepoint 1 and Timepoint 2.
Ees is a measure of right ventricular (RV) - pulmonary arterial (PA) coupling, with a normal value of Ees/Ea \> 0.8 (dimensionless - no units). For subjects with Ees/Ea \> 0.8 at the start of the study, we will evaluate the absolute change in Ees/Ea between timepoints. For those with an Ees/Ea \< 0.8, we will also determine whether participants have an improvement to \> 0.8.
Secondary outcomes
Change in six-minute walk distance (6MWD) in meters.
6MWD will be determined at baseline, timepoint 1 and timepoint 2. Absolute change between these timepoints will be determined.
Change in N-terminal pro-brain natriuretic peptide (NT-proBNP) in picogram/milliliters.
NT-proBNP will be determined at baseline, timepoint 1 and timepoint 2. Absolute change between these timepoints will be determined.
Change in Cardiac index as measured by liters per minute per meters squared at right heart catheterization.
Right heart catheterization will be performed at baseline, timepoint 1 and timepoint 2 and parameters determined. Absolute change between these timepoints will be determined.
Change in pulmonary vascular resistance as measured by Wood units at right heart catheterization.
Right heart catheterization will be performed at baseline, timepoint 1 and timepoint 2 and parameters determined. Absolute change between these timepoints will be determined.
