Summary

Minimally invasive approaches for surgical treatment have been advocated as a treatment option for stand-alone atrial fibrillation (AF). This study will investigate the clinical outcomes after minimally invasive surgical ablation of both paroxysmal and persistent/longstanding persistent AF.

PROCEDURE

Thoracoscopic Atrial fibrillation Ablation

After blunt dissection of the oblique and transverse sinus, an AtriCure Lumitip Dissector was introduced around the pulmonary veins. Pulmonary vein isolation was achieved with an AtriCure Isolator Synergy ablation clamp around the pulmonary vein antrum at least six times for each side. Ganglionated plexus identification and ablation were performed using an AtriCure Synergy ablation pen. The additional superior and inferior ablation lines connecting the bilateral pulmonary vein isolations were created by applying the AtriCure Synergy ablation pen. Following completion of the ablation on the right side, ablation on the left side was accomplished in a similar manner. The ligament of Marshall was dissected by electrical cautery. Conduction block was confirmed upon completion of the ablation procedure on the left side.
