June 2024 PVRI Community Call with Julien Grynblat, David Montani and Stravros Zanos

Transition from parenteral prostanoids to oral selexipag may be considered in select patients with pulmonary arterial hypertension (PAH) to reduce the therapeutic burden imposed on patients and caregivers, but its safety and efficacy remain uncertain.

Pulmonary hypertension (PH) significantly impacts outcomes in heart failure with preserved ejection fraction (HFpEF), especially with right ventricular dysfunction (RVD), yet effective treatments are limited. This study retrospectively evaluated sacubitril-valsartan's effects on pulmonary pressures, RV function, and clinical outcomes in 20 severe HFpEF-PH patients. 

Pulmonary Arterial Hypertension (PAH) is a rare, chronic and progressive disease affecting the heart and lungs. Endothelin receptor antagonist (ERA) + phosphodiesterase type 5 inhibitor (PDE5i) treatment is recommended for all PAH patients. 

Pericardial effusion (PEF) in PAH may be a marker of worsening disease or associated with autoimmune conditions. Sotatercept was not initially reported as associated with the development or progression of PEF. We describe PAH patients taking sotatercept who were found to have new or worsening PEF and examine associated comorbidities.
