BioTrace Medical Announces Key Events Featuring Tempo Temporary Pacing Lead at TCT 2019

BioTrace Medical, Inc., the leader in innovative temporary pacing technology, today announced the company's key activities at the 31^st annual Transcatheter Cardiovascular Therapeutics (TCT) conference, which will take place September 25-29 in San Francisco.

The company's Tempo Temporary Pacing Lead will be featured in a breakfast symposium titled "Keeping the Rhythm with the Tempo Lead: Safety, Stability, and Ambulation for Transcatheter Aortic Valve Replacement (TAVR) and Other Cardiac Procedures," which will be chaired by Stanley J. Chetcuti, M.D., director of the cardiac catheterization laboratory at the University of Michigan Health System, and Tamim M. Nazif, M.D., director of clinical services for the Structural Heart & Valve Center at NewYork-Presbyterian/Columbia University Medical Center.

The symposium will feature recent clinical experience from several leading U.S. structural heart centers, highlighting the safety and efficacy of the Tempo Lead, its use in TAVR procedures, and its positive impact on facilitating post-TAVR patient ambulation outside of the ICU and CCU. The session will also provide an opportunity for hands-on demonstrations. (Symposium registration: https://www.crf.org/tct/program/agenda/satellite-programs?programid=1335)

On Thursday, September 26, Dr. Nazif will discuss NewYork-Presbyterian/Columbia University Medical Center's experience using the Tempo Lead during his presentation titled "Conduction Disturbances After TAVR: Current Thinking and Clinical Relevance."

The Tempo Lead will also be utilized during live case broadcasts from NewYork-Presbyterian/Columbia University Medical Center on Friday, September 27.

Additionally, the company announced the publication of the results of a U.S. multi-center study of 269 cardiac procedures, predominantly TAVR, in Catheterization and Cardiovascular Interventions. The results confirm the Tempo Lead is safe and effective for temporary cardiac pacing, provides stable peri- and post-procedural pacing support, and facilitates post-procedure ambulation.¹ The Tempo lead was successfully positioned and achieved pacing in 264 of 269 patients (98.1%). Two patients (0.8%) experienced loss of pace capture. Procedural mean pace capture threshold (PCT) was 0.7 ± 0.8 mA. There were no safety events, including perforations, pericardial effusions, or sustained device-related arrhythmias. The Tempo lead was left in place post-procedure in 189 patients (71.6%) for a mean duration of 43.3 ± 0.7 hours with a final mean PCT of 0.84 ± 1.04 mA. With the Tempo lead in place, 159 of 189 patients (84.1%) mobilized from bed to chair at a minimum, and 134 patients (70.8%) ambulated without any restrictions related to the pacing lead. There were no lead dislodgments or loss of pace capture events for this group of 189 patients.

The study included procedures performed at six leading U.S. centers: NewYork-Presbyterian/Columbia University Medical Center, University of Michigan Health Center, Riverside Methodist Hospital/OhioHealth, Cleveland Clinic Heart & Vascular Institute, Intermountain Medical Center, and Yale New Haven Hospital.

Since receiving FDA clearance, the Tempo Lead has been used in more than 4,500 U.S. procedures with a safety and performance profile superior to conventional temporary leads, including a 0.04% cardiac perforation rate and a 0.04% dislodgment rate with loss of pace capture.²

About the Tempo Temporary Pacing Lead

BioTrace Medical's Tempo Temporary Pacing Lead is designed for safer, more secure and stable pacing to reduce intraprocedural complications, including perforation and valve embolization. In addition, the Tempo Lead allows patients to ambulate sooner after procedures such as TAVR and TMVR, accelerating recovery times, and enabling patient transfer directly to a step-down or telemetry unit instead of an ICU or CCU. With US FDA clearance and CE certification, the Tempo Lead is the only active fixation temporary pacing lead available in the world. The Tempo Lead's unique design ? featuring novel retractable stabilizer loops and a soft tip ? mitigates the risks of dislodgment and perforation and ensures stability during rapid pacing.
