✦ Synopsis
We report ten successful experiments o f transvenous destruction of the His bundle by laser radiation. An endoscope coupled with a special laser catheter was introduced through the jugular vein into the right atrium of dogs. The tip of thc laser catheter was positioned in front of A-V conduction system under visual control using anatomic landmarks. Injection of saline solution coaxial with the laser power-transmitting fiber was performed before and during laser coagulation. Twenty watts constant wave Nd-YAG laser operating at 1.06 pm was enough to produce complete A-V block in approximately 15 sec. The safety of the proposed technique is especially discussed.
