TI  - [Long term effectiveness of surgical cryoablation for chronic atrial fibrillation 
      in patients undergoing surgery for severe mitral valve regurgitation].
PG  - 151-6
AB  - OBJECTIVE: The objective of the study was to evaluate effectiveness of surgical 
      cryoMAZE ablation for chronic atrial fibrillation (AF) in patients undergoing 
      mitral valve surgical intervention. METHODOLOGY: Forty-seven patients (31 
      females), aged 67.3 +/- 7.3 years who underwent surgical intervention for severe 
      mitral regurgitation were studied. Mitral valvuloplasty was performed in 21 
      patients, and mitral valve replacement in 26 patients. Combined procedure was 
      employed in 35 patients; simultaneous aortocoronary bypass was performed in 16 
      patients, tricuspid valvuloplasty (TVP) in 5 patients, and aortic valve 
      replacement (AVR) in 5 patients. RESULTS: The mean follow-up time was 19 +/- 10 
      months. After 6 or 12 months 36 or 32 patients were seen and 23 (64%) or 22 (69%) 
      of them were in stable sinus rhythm (SR), respectively. In the subset of 24 
      patients with simultaneous intervention on a different valve (TVP or AVR), after 
      6 or 12 months, 14 (74 %) or 15 (83 %) patients had stable SR, respectively. In 
      the follow-up period, 2 patients underwent successful catheter ablation for type 
      I atrial flutter or for a residual left atrial atypical flutter. CONCLUSION: In 
      the study using the method of cryoMAZE ablation for chronic AF performed during 
      the mitral valve surgical intervention, a long-term stable SR was achieved in a 
      high proportion of patients, particularly in patients with simultaneous 
      intervention on two or three different valves.
