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.
Pulmonary artery wedge pressure is a crucial measurement for differentiating between hemodynamic categories of pulmonary hypertension (PH), particularly Groups 1 and 2. In this prospective study, we analyzed the diagnostic utility of checking wedge oxygen saturation to confirm wedge position during right heart catheterization in patients referred for PH.
'Microbes/Parasites and Sex Differences in PVDs' is part of the Virtual Symposium Series by the iPVD, a global education programme that highlights top-notch research on inflammation and infectious PVD.
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.
High-risk acute pulmonary embolism (PE) is associated with significant in-hospital mortality. Large-Bore Mechanical Thrombectomy (LBMT) is a treatment option for acute PE, but data on its efficacy in high-risk PE was limited. This prospective case series reported the outcomes of 14 patients with high-risk PE treated using a novel multipurpose mechanical aspiration system (MMAS).
Pulmonary arterial hypertension (PAH) is a chronic, progressive, and ultimately life-threatening disease characterized by vascular remodeling and increasing pulmonary vascular resistance. Despite significant advances in diagnostic tools and therapeutic strategies, clinical intervention often begins only when patients become symptomatic—typically at New York Heart Association (NYHA) functional class II or higher.
Children with single ventricle heart disease (SVHD) demonstrate decreased arginine/NO metabolism following Stage 2 (Glenn) palliation, associated with poor postoperative outcomes. It is unknown if arginine dysregulation persists at Stage 3 (Fontan).
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but severe complication of pulmonary embolism (PE), yet its underlying mechanisms remain poorly understood. Peptidyl-prolyl cis/trans isomerase (Pin1), a regulatory enzyme involved in thrombosis, inflammation, and vascular remodeling, may contribute to pulmonary vascular disease.
Macitentan 10 mg and tadalafil 40 mg single-tablet combination therapy (M/T STCT) has been evaluated in the global A DUE study (NCT03904693). Here, we report the results of a subgroup analysis in participants from China.
