Successful Robotic Excision and Early Chemotherapy for Primary Cardiac Lymphoma

We present a 67-year-old patient who underwent robotic excision of a mobile left ventricular mass found incidentally on echocardiography. Intraoperative findings revealed a pedunculated mass infiltrating the interventricular septum, and the results of pathologic examination of the frozen section were consistent with malignancy. The final pathologic examination showed a diffuse large B-cell lymphoma, and early chemotherapy was initiated. Follow-up cardiac positron emission tomography/computed tomography showed completely normal myocardium without evidence of malignancy. The lateral endoscopic robotic approach across the mitral valve permitted optimal tumor visualization and early chemotherapy initiation without concern for cardiac rupture or related adverse events.
