Marshfield Clinic Performs the Fist Implant of the Medtronic OmniaSecure ICD Device in Wisconsin

Marshfield Clinic is using the newest technology to help treat dangerous heart arrhythmias for patients.

Marshfield Clinic performed the first implant in Wisconsin of the Medtronic OmniaSecure, the world’s smallest Implantable Cardioverter-Defibrillator (ICD) lead to achieve cardiac resynchronization therapy, in January for a patient at Marshfield Medical Center in Marshfield.

This new technology brings patients’ heart rhythms back to their natural patterns while being less invasive. This is the smallest and thinnest defibrillator lead. The procedure marks a significant milestone for cardiac care in the state and positions Marshfield Clinic among the earliest adopters of this new technology nationwide.

“Performing a first‑in‑state, launch‑day implant requires precision, coordination, and a team ready to rise to the moment,” said Electrophysiologist Dr. Weijia Wang, who performed the procedure. “I’m incredibly proud of the expertise and readiness our staff demonstrated and, most importantly, we delivered an excellent outcome for our patient.”

An ICD lead is a specialized, insulated wire that connects an ICD generator to the patient’s heart. This wire plays a critical and delicate role in monitoring heart rhythms, providing pacing, and delivering life‑saving therapy for dangerous arrhythmia.

Medtronic launched the OmniaSecure™ ICD lead commercially in the United States on Jan. 8. On the same day, Marshfield Clinic was the first in Wisconsin, and among the first nationally, to use the device for left bundle branch area pacing.

Using this advanced pacing approach, Marshfield Clinic electrophysiologists successfully corrected a patient’s left bundle branch block (LBBB) and delivered “Single‑Lead cardiac resynchronization” to treat heart failure.

Traditional cardiac resynchronization therapy typically requires two or three leads. This new approach with fewer components means less trauma to vessels during implantation, a quicker post-procedure recovery and reduced long‑term maintenance issues.

“Patients who have their conduction problem fixed may experience more energy, perform daily tasks better, have fewer heart failure-related hospitalizations,” Wang said.

Dr. Wang said the first patient is “doing excellent,” and her energy level has improved since the procedure. Marshfield Clinic has now performed the procedure on a total of six patients.
