Primary Cardiac Lymphoma Diagnosed With Transesophageal Echocardiography–Guided Endomyocardial Biopsy
A 77-year-old woman presented with a 10-month history of tiredness, shortness of breath, and ankle swelling. Examination revealed signs consistent with right heart failure with marked peripheral edema and auscultatory evidence consistent with tricuspid stenosis.
Transthoracic echocardiography showed a large right atrial mass impinging on the tricuspid valve causing functional tricuspid stenosis (Figure 1⇓).
Endomyocardial biopsy was performed under transesophageal echocardiographic guidance (Figure 2⇓).
Histology confirmed B-cell lymphoma, and radiotherapy was begun. At 1-month follow-up, transthoracic echocardiography showed the right atrial mass to have decreased significantly in size (Figure 3⇓).
