2, ultrasonic monitoring and guide (program complexity, expensive) in the chambers of the heart;
3, continue to monitor esophageal temperature (apparatus defective);
4, gulp down barium, three-dimensional electrolysis according to CT, esophagus and cut open the pre-aligned esophagus travelings of means such as mapping and esophagus sacculus (apparatus defective, can't active treatment);
5, avoid using the 8mm ablation catheter;
6, heavy dose of proton pump inhibitor, omeprazole 40mg1/ day, preceding 1 day of art and postoperative 1 month (treatment indirectly);
7, reach aquation in the art before the art, increase blood volume, rely on local abundant blood flow to take away heat (indirect treatment);
8, energy scheme, high-energy short time (50W+2-5 second, always export 100-250W) and low-yield long-time (25-35W+20-30 second, always export 500-1050W) (sacrifice curative effect).
Said method has been obtained certain effect in clinical, but also has the problem of the following aspects:
1, indirectly treatment: as using proton pump inhibitor and aquation, all be to play a role by promoting the esophageal injury rehabilitation or resist the hot injury indirectly;
2, program complexity, expensive: ultrasonic as using in the chambers of the heart, increase the complicated operation degree, the apparatus costliness is used less at home;
3, sacrifice curative effect: the control PLA melts, and can make the part patient can't obtain real pulmonary vein vestibule electricity and isolate, for palindromia stays hidden danger;
4, apparatus defective: the esophagus probe can only be done monitoring, can not bring into play therapeutical effect.
Therefore, need provide a kind of device that can avoid the esophagus hot injury in the atrial fibrillation catheter ablation.
