ICE-guided cardiac tumor biopsy is a safe and effective method for obtaining histopathological diagnosis while avoiding general sedation and radiation exposure.
May support ICE-guided biopsy for select cardiac tumors; hypothesis-generating and requires prospective validation before wider use.
A 63-year-old woman was admitted to hospital with the chief complaint of new onset chest discomfort and pretibial pitting edema. Transthoracic echocardiography revealed a large invasive tumor on the heart protruding into the right atrium and right ventricle, which obstructed the outflow tract. She underwent transvenous 9Fr, 9-MHz ultra intracardiac echocardiography (ICE) (EP Technologies, Boston Scientific Corporation, San Jose, CA, USA) guided biopsy, and a diagnosis of malignant lymphoma was established from the specimen obtained. ICE-guided cardiac tumor biopsy may be one of the most useful strategies for diagnosis of cardiac tumors.
