Fig 1 Cox-Maze IV (A) right and (B) left atrial lesion sets. In the right atrium, radiofrequency (RF) ablation lines (white lines) extend from the superior vena cava to inferior vena cava and along the right atrium free wall down to tricuspid valve annulus. In the left atrium, RF ablation lines (white lines) are created including pulmonary vein isolation, pulmonary vein roof and floor connecting lesions, lesion from left superior pulmonary vein and amputated atrial appendage, and lesion from inferior atriotomy to mitral valve annulus.
