Abstract:
In atrial fibrillation patients with pectus excavatum, box-shaped pulmonary vein isolation may be preferable due to left atrial posterior wall involvement. However, it needs extra roof and bottom ablation. Preoperative imaging and use of contact force-sensing catheters with three-dimensional mapping are vital for safe and effective procedures.
