SAN DIEGO–(BUSINESS WIRE)–Topera Medical today
announced that its FDA-cleared RhythmView™ 3D mapping and diagnostic system
will be featured in 16 scientific presentations at the 33rd Annual Scientific
Sessions of the Heart Rhythm Society (HRS), May 9-12 in Boston. The presentations will provide
clinicians with additional information about the electrical source of atrial
arrhythmias and will also introduce information on sources that drive
ventricular arrhythmias.

“RhythmView’s
contribution to these presentations speaks to the expanding interest in
applying this 3D mapping platform in clinical practice,” said Edward Kerslake,
Topera Medical’s Chief Executive Officer. “RhythmView’s ability to resolve rotors
in ventricular arrhythmias will be reported for the first time. This represents
an interesting application for RhythmView beyond the atrial rotor mapping
previously reported, and is a logical extension of our platform technology. As
we prepare for the commercial launch in early 2013, we are pleased to see
Topera’s technology taking a lead role in transforming the way
electrophysiology procedures are performed.”

About Topera Medical (www.toperamedical.com)

Topera Medical (Topera, Inc.) has developed the RhythmView™, 3D analysis and
mapping system to assist electrophysiologists in the identification of the
electrical source of complex cardiac arrhythmias. The RhythmView system,
including the RhythmView console and FIRMap™ catheter, is designed to improve
patient outcomes by enabling electrophysiologists to view a dynamic
representation of the electrical activity of the heart, supporting the
diagnosis of and treatment planning for a variety of arrhythmias including
atrial flutter, atrial tachycardia, ventricular tachycardia, and atrial
fibrillation (AF).
