Topera

Topera, Inc. is a cardiac arrhythmia mapping company founded in 2010 by Dr. Sanjiv Narayan and Dr. Ruchir Sehra in San Diego, California. The company developed the FIRMap catheter and RhythmView workstation — an FDA-cleared 3D analysis and mapping system that identifies electrical rotors and focal impulse sources causing atrial fibrillation, atrial flutter, and ventricular tachycardia. The system enables physicians to precisely target these arrhythmia sources during catheter ablation, dramatically improving single-procedure success rates compared to traditional pulmonary vein isolation. Topera's FIRM (Focal Impulse and Rotor Modulation) procedure demonstrated an 82% long-term success rate in clinical trials. The company was acquired by Abbott in late 2014/early 2015 to expand Abbott's catheter-based electrophysiology business.
