Electrophysiological Effects of Long, Linear Atrial Lesions Placed Under Intracardiac Ultrasound Guidance

Abstract

Linear lesions that are electrophysiologically transmural and continuous can be placed in the right atrium of normal pigs. With intracardiac echocardiography, adequate tissue contact over several coil electrodes can be ensured, resulting in short procedure times, efficient energy application, and accurate anatomically linked lesion placement.
