“…Huang and colleagues 8 demonstrated that cryoballoon ablation is a feasible alternative modality for PVI in patients with LAAO devices. Interestingly, it was shown that high-amplitude LAA-like electrograms were present on the surface of Watchman device 9 months after implantation, suggesting endocardialization (coverage with myocardium) of the device surface had occurred.…”

“…Data regarding this issue are limited. A small number of case reports [ 8 , 9 , 10 ] and case series [ 11 , 12 , 13 , 14 , 15 ] with small samples have been carried out to investigate the feasibility and efficacy of LA CA in patients with LAAO devices. However, most patients in prior studies were implanted with nitinol cage devices (e.g., Watchman).…”

Background: Left atrial appendage occlusion (LAAO) is an alternative to oral anticoagulation for thromboembolic prevention in patients with atrial fibrillation (AF). Left atrial (LA) catheter ablation (CA) in patients with LAAO devices has not been well investigated. Here, we report on the safety and efficacy of LA CA in patients with nitinol cage or plug LAAO devices. Methods: A total of 18 patients (aged 67 ± 11 years; 14 males; 5 paroxysmal AF) with LAAO devices (nitinol cage, n = 10; nitinol plug, n = 8) and symptomatic LA tachyarrhythmias were included. Periprocedural and follow-up data were assessed. Results: A total of 20 LA CA procedures were performed at a median of 130 (63, 338) days after LAAO. The strategy of CA consisted of circumferential pulmonary vein isolation (n = 16), linear lesions (n = 14) and complex fractionated atrial electrogram ablation (n = 6). No major adverse events occurred periprocedurally. Repeated transesophageal echocardiography showed no device-related thrombus, newly developed peridevice leakage or device dislodgement. After a median follow-up period of 793 (376, 1090) days, four patients (22%) experienced LA tachyarrhythmias recurrence and two received redo LA CA. No patients suffered stroke or major bleeding events during follow-up. Conclusions: LA CA in patients with LAAO devices (either nitinol cages or nitinol plugs) seems to be safe and efficient in our single-center experience.

“…With increased utilization of LAAO devices, the need for pulmonary vein isolation (PVI) procedures in patients with prior LAAO devices is expected to increase. Several reports have discussed the safety and feasibility of radiofrequency (RF) ablation and cryoablation procedures for this group of patients 3–9 . Complications related to inadvertent ablation over the LAAO device have been associated with RF ablation.…”

Introduction: With the increasing adoption of left atrial appendage occlusion (LAAO) procedures and the eligibility of patients for pulmonary vein isolation (PVI) post device placement, we examined the feasibility and safety of laser balloon (LB) for PVI in patients with prior LAAO.Methods: We retrospectively examined consecutive patients with paroxysmal or persistent, drug-resistant atrial fibrillation (AF) who underwent LB PVI, after Watchman FLX device implantation at Rush University Medical Center between January 2020 and December 2021.Results: Seven patients (four persistent and three paroxysmal) with a mean age of 64 ± 11 years, predominantly male sex (86%), were included in the study. Two (29%) patients had prior cryoablation PVI with recurrence of AF. The mean CHA 2 DS 2 VASc is 2.6 ± 0.5 and the mean HAS-BLED score is 3.4 ± 0.8. The mean follow-up duration was 10 ± 7 months. The mean duration between Watchman FLX device implantation and LB PVI was 592 days. Acute first pass left pulmonary vein (PV) isolation was achieved in 100% of the procedures. There were no periprocedural complications such as death, pericardial tamponade or effusion, phrenic nerve injury, PV stenosis, device perforation or embolization, or worsening peri-device leak in any of the patients. None of the patients had AF recurrence after the blanking period. Conclusion:LB PVI was safe and effective with 100% acute isolation of left-sided veins in patients with prior LAAO device.
