What does right atrial hypertrophy mean? What treatments are available?

Right atrial hypertrophy or enlargement is a result an increased amount of blood in the Right Atrium. This can be due to obstruction downstream, backwards flow across a leaking (“tricuspid”) valve, a defect in the wall between the Left and Right Atrium (an “Atrial-Septal Defect”), or a conduction abnormality to name a few possibilities. It can be diagnosed by EKG, cardiac ECHO and a variety of other tests.

Treatment depends on the underlying cause and may require an operation to fix the abnormality. If the cause is a high blood pressure in the artery to your lungs, it may involve medications if it is due to primary lung disease, and surgery if the cause is a leaky or obstructed Left sided (“Mitral”) valve.

Take look here for more information about your heart:



Some of the causes thus include:

  1. ASD (Atrial Septal Defect)
  2. COPD (Chronic Obstructive Lung Disease)
  3. Pulmonic valve stenosis
  4. Tricuspid valve stenosis + Insufficiency
  5. Mitral valve stenosis + Insufficiency
  6. R+L ventricular failure or CHF (Congestive Heart Failure) .

Hope this helps,

Dr T
