“AFib is a complex rhythm disorder and is the most common abnormal heart rhythm we see in our practice,” explains Suppiramaniam Sreeharikesan, MD, an electrophysiologist at the UPMC Heart and Vascular Institute. “Adding this new procedure advances the level of heart care in the region. Studies have shown PFA can decrease the risk of complications compared with other kinds of ablation, and we know there are patients who will directly benefit from it here in the community.”

PFA uses short bursts of electrical energy delivered through a specially designed catheter to target and destroy the specific heart tissue causing the irregular heartbeat. The short pulses of high-energy electricity create small holes in the cell membrane of the targeted tissue, leading to cell death. The electrical pulses are more specifically targeted, so there is a lower risk of damaging nearby structures, such as the esophagus and phrenic nerve, compared to traditional catheter ablation.

“We know patients want to be in the hospital for as short of a stay as possible. An added benefit of PFAs is that they are generally same-day procedures,” says Dr. Sreeharikesan. “The length of the procedure can vary depending on factors like the size of a patient’s heart chambers and their specific type of AFib. However, most PFA procedures last between one and two hours and require a few additional hours of recovery observation. If a patient is cleared, they are discharged to recover at home. Most patients can then return to their normal routine one week after the procedure.”
