Summary

This study collected real-world data on a medical device that uses extreme cold to treat a type of irregular heartbeat called paroxysmal atrial fibrillation. It involved 295 patients to see how safe and effective the procedure was at preventing the irregular heartbeat from returning. The goal was to gather information on the device's performance after it was already approved for use.
