[Laser destruction of the atrioventricular bundle using the cardiac endoscope].
The results of experiments where endoscopes of various makes were introduced into the right atrium under thoracotomy or transvenously are reported. After visual determination of the A-V node zone, laser coagulation was performed by Nd-YAG laser until complete A-V block was achieved. Various methods of laser cardiac endoscopy application are discussed. Laser destruction of the heart conduction pathways through a cardiac endoscope with a polyurethane balloon appears to be the most convenient technique.
