  • DISCLOSURE Speaker for AtriCure, Edwards

    Lifesciences, LivaNova Consultant for Medtronic Research and educational grants over the

    last 2 years: AtriCure Edwards

  • Surgical AF Ablation:The most important goal for an

    ablation device

    Create conduction block.To do this you must consistently create

    transmural and continuous lesions.Our laboratory and others have shown

    that gaps as small as 1 mm can conduct NSR and AF impulses.

    Notes: This sheep has adhesions of the lungs to his pericardium and it was realy difficult to get to the SVC

    The adhesions also caused a lot of capillary bleeding when the pericardium was opened.

    The adhesions were located on the right side and appear to be due to a history of illness of our sheep
