AB  - BACKGROUND: An enlarged left atrium (LA) is a major risk factor for atrial 
      fibrillation (AF) recurrence after a maze operation. METHODS: Between 2000 and 
      2009, 35 patients underwent circumferential left atrium resection (CLAR), during 
      mitral valve surgery. All patients had continuous AF. RESULTS: Hospital 
      mortalities occurred in two patients (5.7%). Postoperative bleeding occurred in 
      two patients (5.7%). The average follow-up was 64 months. The mean New York Heart 
      Association (NYHA) functional class had significantly decreased to 1.16 +/- 0.37 
      from 2.77 +/- 0.65 (p < 0.01). The mean LA dimension and the cardiothoracic ratio 
      had significantly decreased to 52.8 +/- 7.9 mm, and 0.55 +/- 0.06 from 
      72.6 +/- 11.0 mm, and 0.66 +/- 0.11, respectively (p < 0.01). The mean early 
      postoperative LA volume had decreased to 178 +/- 68 mL (102-343 mL) from 
      332 +/- 133 mL (124-655 mL) (p < 0.001). These LA volume reductions had been 
      maintained until the last echocardiogram, which was done at an average of 29 
      months. In patients who underwent the maze procedure, the rate of sinus rhythm 
      restoration was 82.1%, 81.5%, and 74% at three to six months, one year, and the 
      last visit, respectively. CONCLUSION: CLAR significantly reduced the LA volume. 
      CLAR had an additional beneficial effect with the maze procedure of a relative 
      rate of sinus rhythm restoration. To clarify the role of CLAR in marked symptom 
      improvements after mitral valve surgery in patients with a giant LA, 
      well-designed comparative studies are required.
