Abstract:
Objective To conclude the results of electrophysiological (EP) mapping and ganglianated plexis (GPs) ablation during the minimally invasive atrial fibrillation (AF) surgery.Methods During the period of Sep 2007 to May 2010 to-tally 185 paroxysmal atrial fibrillation cases were recruited receiving the minimally invasive AF surgery with video assistance.The EP mapping was used to test the dual direction block after ablation and the distribution of GPs was recorded.The sinus rhythm rate was followed up after surgery.Results All the minimally invasive surgery were performed successfully withoutdeath in the hospital.There was no permanent pacemaker implant and other serious complications.EP mapping results showed92％ pulmonary vein (PV) potential to the left atrium (LA) could be isolated with the dual direction block for the paroxysmal atrial fibrillation cases.And there were 89％ GPs positive,higher rate than the persistent AF.There were more GPs positive in the right PV area than the left and 86％ GPs lied at the LA domain,not the PV orifice.At least 5 or 6 ablation lesions were needed to get the dual direction block and denervation of the GPs.The sinus rhythm rate after surgery after 3,6,12 and 24months is 83.7％,82.4％,85.4％ and 83.9％.The 12 months follow up data showed the cases with more GPs positive (＞6) had 81.3％ sinus rate and the less GPs positive (≤2) group with 52.6％.Conclusion The EP mapping and GPsablation techniques during the minimally invasive AF ablation surgery could get good sinus rhythm rate during the long term follow up.
