Based on a plenty of different applications, intracardiac echocardiography (ICE) is now a well-established technology in complex electrophysiological procedures. Recently, ICE has become the most widely used ultrasound-based imaging tool to guide diagnostic endomyocardial biopsy (EMB). EMB of cardiac mass guided by ICE is an interesting application of ICE. Allowing a correct positioning of the bioptome, ICE reduce the procedure-related risks and the need of a diagnostic open-chest procedure reserving the more invasive approach to selected cases.
Hereby we report a case series of right ventricular masses in which the EMB was safely and effectively performed under ICE guidance giving essential information for planning the therapeutic strategy.
The diagnosis of both metastatic and primary cardiac tumors relies on the histopathological analyses. The endomyocardial biopsy is a valuable tool for preoperative diagnosis and surgical planning of intracardiac masses suspected for tumors. In our experience, the use of ICE for right ventricle EMB of an intracardiac mass is an attractive modality thanks to the precise localization of the cardiac structures and the ability to guide bioptic withdrawal in the target area.

The whole action of EMB is showed. Fluoroscopy image in RAO view: ICE probe is placed across the tricuspid valve and positioned in the right ventricular inflow tract to image the ventricles in the long axis view. Through a long-deflectable sheath (Agilis, St. Jude Medical, MN, USA) the bioptome is inserted and directed to the mass visualized by ICE. After checking carefully the placement of the bioptome, a sample is taken. (MOV 4285 kb)
