One-year follow-up of a patient with reversible tricuspid valve stenosis due to lymphomatic mass into the right atrioventricular wall.

We present the case of a 66-year-old man with a history of coronary artery disease and chronic lymphocytic leukemia (CLL) who was admitted to the hospital complaining of chest discomfort and shortness of breath on exertion. The echocardiogram revealed a severe pericardial effusion and a large echogenic mass that infiltrated the lateral wall of the right atrium and ventricle and created a moderate tricuspid valve stenosis. B cell intracardiac non-Hodgkin lymphoma/CLL was diagnosed, and the patient was treated with six courses of CHOP chemotherapy. After the third course, the mass disappeared and the patient's general condition was substantially improved.
