title: Diffuse large B-cell lymphoma diagnosed by intracardiac echocardiography-guided cardiac tumor biopsy.
abstract: A 44-year-old man presented with exertional dyspnea. Transthoracic echocardiography (TTE) revealed a large tumor protruding into the right atrium and extending into the left ventricle. Cardiac magnetic resonance imaging and contrast enhanced computed tomography also confirmed the intracardiac tumor detected by TTE. An endomyocardial biopsy was performed under the intracardiac echocardiography (ICE) guidance, and he was diagnosed to have diffuse large B-cell lymphoma following the histological analysis. ICE-guided cardiac tumor biopsy is expected to be a useful diagnostic strategy that can minimize the risk of procedural complications.
