Medical Associates Expands Advanced Heart Care with Two Innovative Treatment Options

Brian Loc, DO

Medical Associates Clinic is expanding advanced heart care by introducing two innovative treatment options for patients with heart failure and abnormal heart rhythms. Medical Associates Cardiologist Brian Loc, DO, is the only provider in the Tri-State area offering both the CardioMEMS™ HF System and the Micra™ Leadless Pacemaker. These minimally invasive treatment options provide eligible patients with access to advanced heart care locally.

The CardioMEMS HF System is an innovative, remote monitoring solution designed to help patients living with heart failure stay healthier and avoid unnecessary hospitalizations. Using a small, implanted sensor that measures pulmonary artery pressure, the system enables clinicians to detect early signs of worsening heart failure and make timely treatment adjustments. By allowing providers to detect changes before symptoms worsen, CardioMEMS can help reduce heart failure-related hospitalizations, improve quality of life, and give patients greater confidence in managing their condition. Clinical studies have shown the technology can reduce heart failure-related hospitalizations by nearly 50% in appropriate patients.

The Micra Leadless Pacemaker is an advanced cardiac pacing technology designed to treat patients with slow heart rhythms using a minimally invasive approach. About the size of a large vitamin capsule, the Micra is implanted directly into the heart through a catheter inserted in the leg, eliminating the need for leads or a chest incision. By reducing the risk of certain complications associated with conventional pacemakers and providing reliable pacing therapy, the Micra Leadless Pacemaker offers eligible patients a safe, effective option that can support improved outcomes, faster recovery, and enhanced quality of life.

"Heart disease doesn't look the same for every patient, so having access to newer technologies allows us to better tailor treatment to each individual's needs," said Dr. Loc. "These procedures give us additional ways to improve outcomes while making treatment less invasive and more convenient for many patients."

CardioMEMS and the Micra Leadless Pacemaker are not appropriate for every patient. Individuals interested in learning whether they may benefit from either treatment should speak with their cardiologist.
