| Research Abstract |
In our institute 43 patients had mapping-guidee direct operation for malignant ventricular tachycardia. After direct operation using incision, excision and/or cryoablation, 4 patients were died of-cardiac failure. To obtained safer operative procedure, intraoperative mapping-guided beam ablation throgh fiberscope was examined experimentarilly. Three methods using YAG laser, miorowave, and radiofrequency wave were examined in dogs. This study demonstrated the technical viability and safey of the fiberscope-guided direct surgery. Intraoperative epicardial ultrasonography can be helpful in making decision of proper laser ablasion size. Both endocardial mapping and ablatin was possible without ventriculotomy. This new method will be an acceptable approach in clinical patient in future.
