From Oral Precision to Parenteral Power: Strategic Transition from Selexipag to Subcutaneous Treprostinil in Advanced Pulmonary Arterial Hypertension

Introduction: When Oral Therapy Reaches Its Ceiling Pulmonary arterial hypertension (PAH) is a disease that rarely forgives therapeutic hesitation. Despite impressive progress in pharmacology over the past two decades, a subset of patients continues to deteriorate even under aggressive combination…

Sotatercept in Pulmonary Arterial Hypertension Associated with Hereditary Hemorrhagic Telangiectasia: Balancing Vascular Repair and Bleeding Risk in a Therapeutic Frontier

Introduction: When Vascular Fragility Meets Vascular Remodeling Pulmonary arterial hypertension (PAH) is a relentlessly progressive disease characterized by pulmonary vascular remodeling, elevated pulmonary vascular resistance, and right ventricular failure. Despite advances in targeted therapies, outcomes remain suboptimal in a subset…

Sotatercept in Pulmonary Arterial Hypertension Associated with Hereditary Hemorrhagic Telangiectasia: Redefining Therapeutic Boundaries in a High-Risk Population

Introduction: When Two Rare Diseases Collide Pulmonary arterial hypertension (PAH) is a progressive and life-limiting disease defined by pathological remodeling of the pulmonary vasculature, increased pulmonary vascular resistance, and eventual right ventricular failure. Despite advances in targeted therapies, PAH remains…
