Primary Cardiac Lymphoma in a Young and Immunocompetent Patient Diagnosed by Percutaneous Transvenous Biopsy.

Primary cardiac lymphoma is a rare cardiac neoplasm that is typically found in older, immunocompromised patients. In this case, we report an immunocompetent, 46-year-old female that presented with shortness of breath and chest discomfort. Diagnosis of primary cardiac lymphoma was confirmed by way of percutaneous transvenous biopsy under transesophageal echocardiography and cardiac fluoroscopy guidance.
