A: Lines of the CryoMaze procedure performed in our institution.2 Blue lines indicate using cryo energy, red lines indicate incision, and orange astarisks indicate gap in this case. B: This figure shows activation map of clockwise rotation M-AFL which related to the gap between PVI line and mitral valve anulus (gap 1). C: This figure shows activation map of LAA AT which related to the gap between PVI line and LAA (gap 2). D: This figure shows activation map of RA M-AT which related to the gap between RA incision and IVC (gap 3).
AT, atrial tachycardia; IVC, inferior vena cava; M-AFL, peri-mitral atrial flutter; PVI, pulmonary vein isolation; LAA, left atrial; LAA, left atrial appendage; RA, right atrial.
