Concomitant microwave ablation for curative treatment of atrial fibrillation (AF)
was performed in 18 patients with history of chronic atrial fibrillation and indication
for open heart surgery, 11 patients with mitral valve replacement and 7 patients with
coronary artery bypass grafting. There were no perioperative complications. During
the postoperative period most of the patients had intermittent AF, they received low
dose Sotalol therapy and electric cardio-versions. Up to now seven patients have reached
follow-up day 90. One patient has persistent AF. Two patients had typical atrial flutter
that was electrically converted to sinus rhythm (SR), isthmus ablation is planned.
The other four patients have SR, one patient without cardioversions. These four patients
show recovered atrial function with observed A-wave for transmitral flow. Under visual
guidance the continuous atrial lesion lines could be induced effectively and safely
by the intraoperative device Lynx.
