Intracardiac echocardiography to guide biopsy for two cases of intracardiac masses.

Pathologic diagnosis of a cardiac mass is vital in determining the proper treatment modality. Open heart surgery or transesophageal echocardiography guided biopsy can be feasible methods to confirm the pathology. However, the former is highly invasive and both methods require general anesthesia. The introduction of intracardiac echocardiography (ICE) can provide good anatomic information of heart and does not require general anesthesia. In this report, we present two cases of cardiac tumors which were confirmed by percutaneous biopsy under the guidance of an ICE. The patients underwent cardiac biopsy without any complications.
