简要总结
This study aims to evaluate the risks of steam pop (POP) and esophageal injury, as well as related influencing parameters, under ultra-high power ablation technology. In the treatment of arrhythmias such as atrial fibrillation, cardiac ablation surgery is a common method. The use of ultra-high power ablation technology can shorten the operation time and improve effectiveness, but it may also increase the risk of damage to surrounding structures such as the esophagus. We will recruit a certain number of patients who are scheduled to undergo ultra-high power ablation surgery. We will record various parameters during the surgery, such as energy, time, and contact force, and monitor patients for signs of esophageal injury after the surgery. We expect that through this study, we can better understand the potential risks of ultra-high power ablation to the esophagus and identify the key parameters affecting these risks. This will help to improve surgical techniques, reduce complications, and enhance patient safety and surgical outcomes.
