Nation's first cardiac ablation with mapping system recently cleared by the FDA performed at Penn Medicine

After eight years of failed treatment for persistent atrial fibrillation (AF), a New Jersey patient became the first patient in the United States to undergo cardiac ablation -- a procedure in which an electrophysiologist will scar or destroy tissue in the heart that's allowing incorrect electrical signals to cause an abnormal heart rhythm -- using an intraoperative imaging and mapping system recently cleared by the Food and Drug Administration (FDA).
