Domestic and international to alleviate the main method that esophagus heat waste injures in prevention left atrium-esophageal fistula generation as follows at present:
1, strictly energy that LAPW melts and temperature (sacrifice curative effect) is controlled;
2, intracardiac echocardiography monitoring and guide (program is complicated, expensive);
3, esophageal temperature (apparatus defect) is continued to monitor;
4, according to CT, esophagus gulps down barium, three-dimensional electrolysis cuts open mapping and the pre-aligned esophagus traveling of means such as esophagus sacculus (apparatus defect, cannot active treatment);
5, avoid using 8mm ablation catheter;
6, heavy dose of proton pump inhibitor, omeprazole 40mg1/ day, preoperative 1 day and month after operation (indirect treatment);
7, aquation in preoperative and art, increases blood volume, relies on the abundant blood flow in local to take away heat (indirect treatment);
8, powering 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 achieves certain effect in clinical, but also there is the problem of the following aspects:
1, indirect treatment: as used proton pump inhibitor and aquation is all indirectly by promotion esophageal injury rehabilitation or resist hot injury and play a role;
2, program is complicated, expensive: as used intracardiac echocardiography, increase complicated operation degree, apparatus is expensive, applies less at home;
3, curative effect is sacrificed: control PLA and melt, some patients can be made cannot to obtain real Pulmonary venous vestibule electric isolution, for palindromia leaves hidden danger;
4, apparatus defect: esophagus probe can only be monitored, can not play therapeutical effect.
Therefore, the device that a kind of esophagus hot injury that can avoid in atrial fibrillation catheter ablation is provided is needed.
