Fig 1 Right atrial diagram of surgical incisions and cryoablation patterns for the limited right atrial maze procedure. Cross-hatched areas indicate cryolesions, dashed lines are surgical incisions, and lines with slashes are suture lines. The procedure is performed in the following steps: A, excise right atrial appendage (RAA), open the atrium laterally and excise excess tissue, connect incision to superior vena cava (SVC) with cryolesion; B, cryolesion across isthmus; C, incise from initial incision to tricuspid valve and finish with cryolesion; and D, open atrial septal defect (ASD), unroof coronary sinus (CS), or cryolesion between the two. (IVC = inferior vena cava.) The Annals of Thoracic Surgery 2002 74, 1992-1997DOI: (10.1016/S0003-4975(02)04123-1)
