New ablation technique aims to zap heart flutter with less radiation and greater precision

This trial tests a new way to treat typical atrial flutter, a heart rhythm problem. Instead of the standard linear ablation, doctors use a special catheter with tiny sensors to map and target only the high-voltage areas causing the flutter. The goal is to see if this approach is as effective as the standard method while using less radiation and fewer burns. About 100 adults with atrial flutter will be randomly assigned to one of the two techniques, and the results will be checked during the procedure and afterward.
