title: Biopsy of a complicated right atrial mass using CARTO 3-dimensional electro-anatomic mapping.
abstract: We report the successful biopsy of a right atrial fatty mass using CARTO 3-dimensional electro-anatomic mapping fused with cardiac MRI. Fluoroscopic guidance within the cardiac chambers lacks precision and therefore risks geographical miss of the intended target and cardiac perforation. CARTO mapping fused with cardiac MRI facilitated precise navigation of the bioptome thereby ensuring a successful biopsy of the intended tissue while minimizing the risks of inadvertent trauma to adjacent tissue.
