This case achieved short-term recovery of cardiac function and long-term maintenance of pulmonary vascular stability and demonstrates that the transcatheter Potts shunt is a feasible and effective life-prolonging treatment option for severe PAH, even in patients with a history of prior PDA closure.

The expression of tRNA-derived small RNA (tsRNA) in IPAH tissues remains unknown. tsRNA sequencing was conducted on lung tissue samples obtained from patients with IPAH and healthy controls.

This study quantified the recent real-world burden of pulmonary arterial hypertension (PAH) using US real-world data.

Mephedrone is a synthetic cathinone with sympathomimetic effects, but has not previously been linked to pulmonary arterial hypertension (PAH).

Pulmonary arterial hypertension (PAH) is a severe cardiopulmonary disease associated with substantial morbidity and mortality.

In this PH Community Call, we discussed: 

• The Pediatric Pulmonary Hypertension International Risk Score: A Prediction Model for Outcomes Using Machine Learning by Megan Griffiths
• Placental growth factor promotes endothelial activation and inflammatory remodelling in pulmonary hypertension by My Ngoc Ha

Pulmonary arterial hypertension (PAH) was historically viewed as a disease of young adults; however, emerging evidence suggests rising prevalence in the elderly, which is an insufficiently characterized population. 

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.

Pediatric pulmonary arterial hypertension is a progressive vasculopathy with substantial early mortality. Subcutaneous treprostinil is an established prostacyclin-pathway therapy for higher-risk disease, but long-term pediatric data from Latin American referral centers remain limited.
