Histopathological changes following laser ablation of a left-sided accessory pathway in a human.
Laser ablation was performed intraoperatively in a patient with coronary artery disease and Wolff-Parkinson-White syndrome. Histopathological evaluation of the laser ablation site revealed a transverse laser incision in the left atrial septum and mitral valve annulus. There was hemorrhage in the atrioventricular (AV) groove with interruption of a posterolateral AV connection. The laser lesion was confined largely to the atrial aspect of the AV annulus. We conclude that laser catheter ablation of accessory pathways is feasible in humans.
