[Intracardiac echocardiography-guided cardiac tumor mass biopsy]

Primary cardiac tumors are rare and often occur without major symptoms. The appropriate therapy for cardiac tumors without metastasis is surgical resection and chemotherapy. However, for certain patients, when the tumor cannot be safely removed, biopsy is recommended since it allows histology examination and further therapeutical considerations. The aim of our case presentation is to describe the case of a 56-year-old woman, in whom cardiac tumor-mass was revealed because of recurrent pericardial fluids. The mass appeared to be non-resectable, therefore biopsy with an eventual histological examination was planned. Intracardiac echocardiography guided percutaneous biopsy was performed. Intracardiac ultrasound ensured accurate localization of the tumor, the catheter-based grasping device and the excision could be instantly monitored. This case demonstrates that an intracardiac ultrasound-guided tumor mass biopsy is a feasible method, which increases accuracy and ensures safety.
