Cardiac Involvement with Diffuse Large B Cell Lymphoma

A 62-year-old man with dyspnea on exertion New York Heart Association (NYHA) functional class III was admitted to our hospital. He had dyspnea on exertion since several months ago that aggravated since two weeks ago. In the past medical history, he had generalized lymphoadenopathy that was diagnosed as non-specific reactive response in lymph nodes. Physical examinations showed diastolic rumbles in the left sternal border and generalized lymphoadenopathy. Additionally, transthoracic and transesophageal echocardiography showed large heterogeneous mobile mass (80 * 60 mm) attached to the inter-atrial septum protruding to the right ventricular inflow, which resulted in severe tricuspid stenosis (mean gradient = 13 mmHg).
