New Leadless Pacemakers Show Great Promise


Leadless PacemakerPacemakers can vastly improve quality of life for individuals with irregular heart rhythms. However, there were always risks associated with the surgically implanted devices, including infection and breakage of the wires that connect the device to the heart.

These complications may be significantly improved by a new leadless, self-contained version currently in clinical trials at Cleveland Clinic.

“We’re seeing a shift in the field,” says Cleveland Clinic electrophysiologist Daniel J. Cantillon, MD, with the Sydell and Arnold Miller Family Heart & Vascular Institute, who was a leading investigator in the multicenter trial. “The weakest link in traditional pacemaker systems is the lead wire and the surgical pocket. The leadless systems have neither, so in effect they break through that ceiling of limitations that have been in place for 60 years, and into a new era.”
