UP Health System–Marquette offers new procedure for atrial fibrillation
MARQUETTE — UP Health System-Marquette is now offering pulsed field ablation, a minimally invasive outpatient procedure to treat atrial fibrillation, the most common type of abnormal heart rhythm.
AFib is a progressive condition affecting millions of people worldwide and is associated with an increased risk of stroke, heart failure and cardiovascular-related hospitalizations. Symptoms may include heart palpitations, fatigue, shortness of breath, chest discomfort and lightheadedness, though some individuals experience no symptoms. Adults over age 40 face an increased lifetime risk of developing AFib, and many people remain undiagnosed until complications occur.
Cardiac electrophysiologists at UPHS-Marquette recently performed the procedure using a new technology that delivers pulsed electric fields through a specialized catheter to interrupt irregular electrical pathways in the heart that trigger AFib. Unlike traditional ablation methods that use heat or cold, this new technology is non-thermal and is designed to reduce the risk of damage to surrounding heart structures while improving procedure efficiency.
“Bringing advanced technologies like pulsed field ablation to our region reflects our continued commitment to expanding access to high-quality heart care close to home,” said Tonya Darner, market chief executive officer of UPHS – Marquette and UPHS – Bell. “Offering innovative, minimally invasive treatments like this furthers our commitment to making communities healthier.”
Catheter ablation is a safe and effective treatment option when medications do not adequately control abnormal heart rhythms. Early diagnosis and treatment of AFib can help reduce the risk of serious complications and improve quality of life. Anyone experiencing symptoms such as chest pain or fainting should seek immediate medical attention by calling 911.
