[Decompensated pulmonary hypertension]

Area of Science:

• Cardiology
• Pulmonology
• Critical Care Medicine

Context:

• Right ventricular failure (RVF) complicates acute respiratory distress syndrome (ARDS), pulmonary embolism (PE), and pulmonary hypertension (PHT).
• RVF poses significant clinical and intensive care challenges, particularly when associated with PHT.
• Current definitions for acute and chronic RVF lack universal recognition, emphasizing the importance of clinical presentation and hemodynamics.

Purpose:

• To explore the complexities of right ventricular failure in the context of pulmonary hypertension.
• To highlight the therapeutic strategies for managing RVF, focusing on balancing preload and afterload.
• To underscore the critical need for early detection of worsening PHT and prevention of acute right heart failure.

Summary:

• RVF management involves optimizing preload and afterload, utilizing inotropic agents like dobutamine, and inodilators to enhance contractility.
• Lowering pulmonary vascular resistance is the primary therapeutic goal to reduce right ventricular afterload.
• Breaking the cycle of acute right heart syndrome is difficult, necessitating early PHT monitoring and intervention.

Impact:

• This understanding aids clinicians in managing RVF, a severe complication of PHT.
• Identifies key therapeutic targets, including reducing pulmonary vascular resistance and enhancing RV contractility.
• Suggests advanced interventions like lung transplantation or surgical atrioseptostomy for refractory cases.
