MUSC first academic medical center to perform ‘game-changing’ new heart procedureApril 18, 2022
Minimally invasive ‘Barostim’ device could improve quality of life for heart failure patients
Two doctors at MUSC Health are the first at an academic medical center and only the second in the world to use a new, minimally invasive procedure to implant a heart failure treatment device.
Both doctors are women in heavily male-dominated specialties. Vascular surgeon Jean Marie Ruddy, M.D., is principal investigator at the MUSC site for the trial of this new implantation method for Barostim. Cardiac electrophysiologist Anne Kroman, D.O., Ph.D., is site co-principal investigator of the BATwire percutaneous implant study, using the Barostim Neo System.
Barostim won breakthrough device approval from the U.S. Food and Drug Administration in 2019 following successful trials led by MUSC Health cardiologist Michael Zile, M.D. The device uses electrical impulses to stimulate the nerve that regulates blood pressure, inducing the blood vessels to relax.
Although the device can’t reverse heart failure, it can improve patients’ quality of life, said MUSC Cardiologist Ryan Tedford, M.D., section chief of heart failure, medical director of cardiac transplantation and professor in the College of Medicine.
His patient became the first at MUSC Health to undergo the new method of implantation last week and is doing well.
The original method of implantation required a vascular surgeon to make an incision in the patient’s neck to insert the electrode. But in a “feat of engineering,” the new method being tested would enable the device to be implanted through a wire using ultrasound guidance, Ruddy said.
“This is what we call a ‘first-in-man study.” It’s a new way to deliver the same technology but to save the patient from an incision in the side of the neck,” she explained.
“There are millions of patients living with heart failure with reduced ejection fraction in the U.S. who may be able to benefit from Barostim. This new implantation method could eventually be used for most patients who may benefit from Barostim and represents a step forward in the evolution of the therapy to be even more simple to implant,” explained a spokesperson with CVRx, the company that created Barostim.

MUSC and its affiliates have collective annual budgets totaling $4.4 billion. The nearly 25,000 MUSC team members include world-class faculty, physicians, specialty providers, scientists, students, affiliates and care team members who deliver and support groundbreaking education, research, and patient care.
CVRx is focused on the development and commercialization of Barostim™, the first medical technology approved by FDA that uses neuromodulation to improve the symptoms of patients with heart failure. Barostim is an implantable device that delivers electrical pulses to baroreceptors located in the wall of the carotid artery. Baroreceptors activate the body’s baroreflex, which in turn triggers an autonomic response to the heart. The therapy is designed to restore balance to the autonomic nervous system and thereby reduce the symptoms of heart failure. Barostim received the FDA Breakthrough Device designation and is FDA-approved for use in heart failure patients in the U.S. It has also received the CE Mark for heart failure and resistant hypertension in the European Economic Area.
