The activin signaling inhibitor sotatercept was approved for Group 1 pulmonary arterial hypertension (PAH) based on Phase 2 and 3 clinical trials showing significant improvements in primary outcomes; reduced pulmonary vascular resistance (PVR) and increased 6-min walk distance (6MWD), respectively.

The Women's Health Task Force was relaunched to address the intersection of women's health and pulmonary vascular disease. The webinar includes research presentations on sex differences and sex hormone treatments in pulmonary arterial hypertension (PAH). Studies show that this disease primarily affects women, but men have worse survival. There has been significant research on the role of sex hormones in this disparity including the phase 3 trial of anastrozole that was presented. 

Pulmonary arterial hypertension (PAH) is characterized by vasoconstriction, proliferation, fibrosis, and microthrombosis of the pulmonary vasculature, which causes elevated pulmonary arterial pressure and vascular resistance leading to right ventricular failure and death.

Pulmonary hypertension is common in children with Trisomy 21, frequently with multifactorial aetiologies. Registry data provide better understanding of disease development, diagnostic workup and treatment patterns in children with Trisomy 21. TOPP (Tracking Outcomes and Practice in Pediatric Pulmonary Hypertension) is a centre-based, comprehensive registry. 

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but serious disease caused by persistent thromboembolic obstruction or narrowing of the pulmonary arteries. Its prevalence varies, and many cases remain undiagnosed, contributing to a substantial clinical burden.

Part of the 'Hypoxia in pulmonary vascular research – altitude and beyond' webinar series by the High Altitude Task Force, who raise awareness and understanding of PH linked to high altitude and organise scientific conferences in regions affected by high altitudes. 

Pulmonary emboli (PE) are a common clinical problem seen when a peripheral deep vein thrombosis (DVT) migrates to the pulmonary arteries. However, emerging literature suggests that not all filling defects in the pulmonary arteries are the result of embolism, and that in situ pulmonary arterial thrombus (ISPAT) or low-flow stasis artifact (LFSA) within the pulmonary arteries can mimic acute PE. 

Pediatric pulmonary arterial hypertension (PAH) has a long asymptomatic period with progressive vascular loss. A recent computational model of simulated PAH in humans has demonstrated that up to 70% of the pulmonary vasculature is lost before clinical PAH criteria are met.

Pulmonary endarterectomy (PEA) is the gold standard treatment for chronic thromboembolic pulmonary hypertension (CTEPH). While balloon pulmonary angioplasty (BPA) is an emerging treatment for distal CTEPH, a standard therapeutic strategy for CTEPH with unilateral central lesions has yet to be established. 

This patient-focused webinar explored the findings from the Pulmonary Hypertension Global Patient Survey (PHGPS) – with a focus on adult data across Europe.
