Abstract:
Transthoracic, transesophageal, and intracardiac echocardiography are applicable imaging tools used for increasing the accuracy of tumor positioning during transvenous intracardiac tumor biopsy. However, incorporating echo-images in the extremely rare procedures is usually not easy. By using a contralateral catheter for simultaneous contrast injection and tip positioning, we demonstrated tumor biopsy safely and effectively in 4 cases without the guidance of echocardiography.
