Pulmonary Valve Regurgitation (PVR)

Pulmonary Valve Regurgitation (PVR) is a condition where the pulmonary valve, responsible for controlling blood flow from the heart to the lungs, does not function properly. Instead of closing tightly, it allows blood to flow back into the heart, causing potential health issues. In this guide, we’ll break down PVR into understandable terms, covering types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.

Types of Pulmonary Valve Regurgitation:

There are two primary types of PVR: acute and chronic. Acute PVR occurs suddenly, often due to an injury or infection. Chronic PVR develops over time, usually resulting from congenital heart defects or other long-term conditions.

Causes of Pulmonary Valve Regurgitation:

  1. Congenital Heart Defects: Defects present at birth affecting the pulmonary valve.
  2. Endocarditis: An infection affecting the heart valves.
  3. Pulmonary Hypertension: High blood pressure in the lungs.
  4. Rheumatic Fever: A complication of untreated strep throat.
  5. Carcinoid Tumors: Tumors that produce hormones affecting the heart.
  6. Marfan Syndrome: A genetic disorder affecting connective tissues.
  7. Dilated Pulmonary Artery: Enlargement of the artery leading to the lungs.
  8. Trauma: Injury to the chest or heart area.
  9. Pulmonary Valve Stenosis: Narrowing of the pulmonary valve.
