A self-expanding circular-tipped cryoablation catheter may allow for rapid and effective isolation of multiple pulmonary veins in a single procedure for patients with paroxysmal AF.
May support single-procedure PV isolation with novel cryo catheter in paroxysmal AF; hypothesis-generating and requires randomized confirmation before practice change.
Although radiofrequency pulmonary vein (PV) ablation is effective in the treatment of atrial fibrillation (AF), it is associated with small but significant risks of PV stenosis and systemic thromboembolism. The characteristics of cryothermic tissue injury may reduce the likelihood of such complications, but using conventionally tipped cryoablation catheters can be time consuming and may, thus, not permit isolation of all PVs during a single procedure. We describe a case of rapid and effective isolation of all electrically connected PVs in a patient with paroxysmal AF, using a percutaneous self-expanding circular-tipped cryoablation catheter.
