2. Fig 1
Schematic illustration of the current Cox Maze III modification. Cryolesions are represented by the shaded lines and the portions of muscles to be resected are in stripes. Sharp incisions are represented by stitch marks. Procedures a–n are detailed in the text. (CS = coronary sinus; IVC = inferior vena cava; LAA = left atrial auricle; LSA = left sinus node artery; PSA = posterior sinus node artery; RSA = right sinus node artery; SN = sinus node; TV = tricuspid valve annulus.)

Technical illustration of the current modification of the Maze procedure. (A) The anterior view of the posterior left atrial wall; sites of the sharp incisions and cryolesions. (B) The posterior view of the left and right heart; the completed modified Maze procedure. Sharp incisions repaired with sutures are represented by the stitch marks, whereas the cryoablated areas are indicated by the dotted lines. (CS = coronary sinus; IVC = inferior vena cava; LAA = left atrial auricle; LIPV = left inferior pulmonary vein; LSPV = left superior pulmonary vein; MV = mitral valve; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein; SVC = superior vena cava.)

Evaluation of left atrial transmitral A-wave velocity after the Maze procedure. Within each group, there was a significant increase in the A-wave velocity over time. Although the larger value of the A-wave velocity noted in group II was statistically significant only in the early postoperative period, a definite trend showing a larger A-wave velocity in group II was present.
