September 2025 PVRI Community Call with Grazyna Kwapiszewska, Slaven Crnkovic and Athiththan Yogeswaran

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 arterial hypertension (PAH) is a pulmonary disease associated with alterations in gut microbiota. We aimed to identify potential diagnostic genes causally associated with gut microbiota and PAH.

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.
