ABSTRACT

Objective To sunomanize the experience of consecutive 353 patients and mean 2-years follow-up following Mei mini maze procedure for atrial fibrillation.Methods Between June 2010 and May 2015,353 patients(240 males, 113 females) of atrial fibrillation received this therapy.The age of these patients were(59.7 ± 8.5) years.Among them, 186 were with paroxysmal and 167 were with non-paroxysmal.The procedure, through three ports on left chest wall, included pulmonary vein isolation and ablations of the roof and posterior wall of left atrium which were achieved by bipolar radiofrequency ablation.Ganglionic plexus ablation was made by the ablation pen.Left atrial appendage was excluded.Results Durations of their procedures were(92.3 ± 19.1) mins.No conversion to sternotomy or pacemaker implantation occurred and none of the patients died.The hospital stay was(8.5 ± 2.1) days.The mean follow-up duration was (25.0 ± 15.1) months.308 (90.1％) patients were in sinus rhythm.34 patients could not maintain sinus rhythm.Stroke, thrombus in the left atrium and stenosis of pulmonary vein were not found after their procedures.Conclusion Mei mini maze procedure is a safe, effective, and appropiiate treatment for AF, which restores sinus rhythm and may be associated with the prevention of AF-related stroke.It deserved to be promoted in future.
