This case highlights Graves' disease as a potentially reversible cause of pulmonary hypertension and isolated right heart failure.
Reversible PH after Graves' treatment in one case; hypothesis-generating and should not yet change practice.
A 38-year-old man from a remote tribal area of South India presented with right heart failure. On evaluation, he was found to have untreated Graves' disease (GD) with atrial fibrillation and pulmonary hypertension. The left ventricular function was normal. Secondary causes for pulmonary hypertension were ruled out. He was treated with carbimazole and low-dose propranolol. Post 4 months medical therapy, his pulmonary hypertension completely reversed, thus establishing GD as a reversible cause of pulmonary hypertension and isolated right heart failure.
