Study Summary

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.

Primary Outcome

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.
