Abstract
Tachyarrhythmias are corrected by in vivo ablation of human heart tissue employing laser energy delivered by means of elongated optical fibers in a series of short discrete pulses to sites of tachyarrhythmia foci. The operation may be conducted by a thoracotomy or by means of an optical fiber carried by a catheter passed into the heart via a blood vessel. An argon ion laser is preferred. The processes have been demonstrated successfully in 20 clinical operations pursuant to an experimental protocol.
