Rheumatic pulmonary valve failure

Last edited: 4/23/2026

Overview

Rheumatic pulmonary valve failure involves dysfunction of the pulmonary valve due to prior rheumatic heart disease, leading to symptoms such as dyspnea, fatigue, and signs of right-sided heart failure 1.

Diagnosis

  • Clinical history of rheumatic fever or heart disease
  • Echocardiography to assess valve morphology and function
  • Chest X-ray showing signs of pulmonary congestion or enlargement
  • Electrocardiogram (ECG) for right heart strain patterns
  • Hemodynamic assessment via right heart catheterization in severe cases 1

    • Management

  • First-line treatments: Diuretics (e.g., furosemide) to manage fluid overload 1
  • Adjunctive therapies: Vasodilators like phosphodiesterase-5 inhibitors (e.g., sildenafil) to reduce pulmonary artery pressure 1
  • Antibiotics: Prophylactic antibiotics to prevent infective endocarditis 1
  • Management of complications: Addressing encephalopathy with careful fluid management, avoiding aminophylline, and correcting cerebral alkalosis 1

    • Special Populations

  • Encephalopathy risk: Increased caution with fluid and electrolyte management in patients receiving aminophylline or at risk of hypotension 1

    • Key Recommendations

  • Closely monitor fluid balance and correct cerebral alkalosis in patients with signs of encephalopathy following treatment 1 (Evidence: Strong)
  • Use diuretics judiciously to manage fluid overload in rheumatic pulmonary valve failure 1 (Evidence: Moderate)
  • Avoid aminophylline in patients with compromised cerebral perfusion to prevent encephalopathy 1 (Evidence: Expert opinion)
