Key result
Redo RF PVI proves feasible and safe in a patient with a prior Amulet device.
Why the study?
There is limited data on the feasibility and safety of pulmonary vein isolation after implantation of left atrial appendage occlusion devices other than Watchman.
Is redo radiofrequency pulmonary vein isolation ablation safe and feasible in a patient with a prior Amulet left atrial appendage occlusion device?
Case Report (n=1)
No
Is redo radiofrequency pulmonary vein isolation ablation safe and feasible in a patient with a prior Amulet left atrial appendage occlusion device?
This case report provides initial evidence on the feasibility and safety of performing a redo radiofrequency pulmonary vein isolation in a patient with a previously implanted Amulet left atrial appendage occlusion device.
Answers are grounded in this paper and cite their sources.
May support feasibility in isolated cases; leaves open need for prospective safety data before wider use.
Left atrial appendage occlusion (LAAO) devices are increasingly being used in patients with elevated stroke risk who also have high bleeding risk, but who are unable to take long-term anticoagulation.1 Safety of atrial fibrillation (AF) ablation following Watchman (Boston Scientific, Natick, MA) device implantation has been reported.2 However, there is limited data on the feasibility and safety of pulmonary vein isolation (PVI) after implantation of other LAAO devices. We present the case of a patient with history of PVI using cryotherapy and prior implantation of an Amulet device (Abbott, Lake Bluff, IL) who underwent a redo radiofrequency (RF) ablation PVI at our institution.

Pietrasik et al. (2020) conducted a case report in Atrial fibrillation (n=1). Redo radiofrequency pulmonary vein isolation ablation was evaluated on Safety and feasibility. Redo radiofrequency pulmonary vein isolation ablation was presented in a case report to evaluate its safety and feasibility in a patient with a prior Amulet device implantation.
