Among 17 patients who underwent the Maze procedure, recurrent atrial arrhythmia developed in 8 patients. Among 30 patients without preoperative atrial arrhythmia, novel atrial arrhythmia developed in 2 patients. The RA volume index was a significant predictor according to the multivariate analysis (P\u2009=\u20090.003). The RA volume index showed a significant positive correlation with the RV end-diastolic pressure (P\u2009&lt;\u20090.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The RA volume predicts the development of atrial arrhythmia after PVR in patients with repaired TOF.
