ANN ARBOR, Mich. – Trinity Health Ann Arbor announced they completed Michigan’s first ever ablation procedure to treat Atrial Fibrillation (AFib).
Medical workers used the Varipulse Platform, a medical technology approved by the FDA in November 2024. According to Trinity Health, this is the first-of-its-kind procedure in Michigan using pulsed field ablation, and it was successfully performed in April 2025.

What is Varipulse Platform?
Trinity Health Ann Arbor said the Varipulse Platform is a more effective way to correct irregular heartbeats.
Using pulsed field ablation, the tool can precisely target and control the creation of cardiac scars, guided by real-time three-dimensional mapping, blocking the faulty electrical signals that cause AFib. This can help reduce the need for X-ray-based fluoroscopy, meaning it can help lower health care costs and minimize patient radiation exposure.
“If you think of electrophysiologists as the electricians of the heart, what this advancement allows for is a real-time scan of the heart’s structure and the ability to send short, targeted bursts of electrical energy to interrupt faulty electrical signals in problem areas with greater safety and precision for our patients,” said Mohammad-Ali Jazayeri, M.D., an electrophysiologist at Trinity Health Michigan Heart - Ann Arbor Campus. “The potential for our patients is significant. We can deliver a safer and potentially more effective long-term solution, while also reducing procedure times — including the time spent under anesthesia — and recovery times. Ultimately, and most importantly, we can deliver better outcomes for our patients.”
According to Trinity Health Ann Arbor, the hospital is home to one of Michigan’s largest arrhythmia treatment centers.
“To have the expertise, resources, and technology available to treat patients’ most complex heart arrhythmias, it’s a very comforting feeling knowing we are among the most elite and capable centers in America,” said Jihn D. Han, MD, Medical Director of the Electrophysiology Lab at Trinity Health Ann Arbor. “The adoption and integration of this technology into our Electrophysiology Lab allows us to take on the most challenging cases, all with greater precision and confidence.”
