SAN DIEGO--(BUSINESS WIRE)--Topera Medical today announced the completion of initial independent clinical cases utilizing the Company’s RhythmView™3D mapping system for identifying the specific sources that drive and sustain atrial fibrillation (AF). Twelve electrophysiologists at eight sites across the U.S. evaluated the RhythmView system in more than 30 patients suffering from paroxysmal, persistent and long-standing persistent AF. 3D FIRMaps™ produced by the RhythmView system enabled clinicians to identify in all patients the sources of AF, such as rotors and focal beats. Multiple simultaneous sources were identified in the majority of cases.
