To assess periprocedural and long term results of radiofrequency modified MAZE procedure and role of each step in treatment of lone AF.
128 patients (98 male, mean age 54.5±9.6) with AF were included. According to duration of AF 5 groups (G) were allocated. G I – paroxysmal AF (n=26), II – 7 days – 1 month persistence AF (n=30), III – 2 – 5 months persistence AF (n=16), IV – 6-12 months persistence AF (n=29), V – long standing AF. Arithmetical means: bypass time – 60.4±15 min., LA volume – 133.1±26.5 ml., LA diameter – 4.5±0.61. Sinus Rhythm restoration was observed in G I: 81.82 %; G II: 85.4 %; G III: 78.6 %; G IV 64 %; G V 52 %. Mean follow-up has made 36 months. Average effectiveness has made 84 % (86, 89, 75, 83, 66 % in Gs I, II, III, IV, V respectively). No deaths or major complications were registered.
Patients with duration of AF 6 months and more biatrial approach is recommended. RF modified MAZE procedure is effective and safe approach for surgical treatment of lone AF according to gathered data.
