Laser valvuloplasty does not damage cardiac conduction tissue Available to Purchase

The clinical usefulness of laser techniques in cardiac valve operations may be limited by the possibility of damaging normal cardiac tissues especially the cardiac conduction system. During this experiment a portion of the Aortic valve annulus that is in close proximity to the bundle of His was exposed to various levels of laser power from the Nd-YAG. There was no evidence either grossly or microscopically of damage to the cardiac conduction system.
