Background. Combined atrial fibrillation (AF) ablation and left atrial appendage closure (LAAC) has been practiced for management of both the symptoms and the high stroke risk of AF. Data of the combined procedure in selected patients with prior stroke are limited. The aim of this study is to compare the safety and efficacy of combined catheter ablation and LAAC between AF patients with and without prior stroke. Methods and Results. This retrospective study enrolled 296 patients who underwent combined procedures of AF ablation and LAAC. Patients were divided into two groups: 81 patients with prior stroke (Stroke group) and 215 patients without prior stroke (Control group). Combined procedures were successfully performed in all the patients. Patients in the Stroke group had higher CHA2DS2-VASc scores (4.9 ± 1.2 vs. 3.2 ± 1.0, P < 0.001 ) and higher HAS-BLED scores (3.5 ± 1.1 vs. 3.0 ± 1.0, P < 0.001 ) compared with those in the Control group. Procedure-related complications in the Stroke group included two pericardial effusions and two groin hematomas, which did not differ significantly fromthe Control group (4.9% vs. 4.2%, P = 0.778 ). After a mean follow-up of 20 months, the AF-free rate of the Stroke group was comparable with that of the Control group (64.2% vs. 68.4%, P = 0.495 ). The relative risk reductions in stroke and bleeding (observed rate compared to that predicted from the CHA2DS2-VASc and HAS-BLED scores) were 80% and 79%, respectively, in the Stroke group, and 62% and 62%, respectively, in the Control group. Conclusions. The combination of catheter ablation and LAAC is safe and efficient in selected AF patients with prior stroke. It was observed that patients with prior stroke may benefit more from risk reductions of stroke and bleeding following the combined procedure.

Combined Strategy

Introduction: Percutaneous left atrial appendage closure (LAAC) is an alternative to oral anticoagulant (OAC) in patients with non-valvular atrial fibrillation (AF) and contraindication to long-term OAC. Combined strategy with percutaneous LAAC at the same time of other cardiac structural or electrophysiological procedure has emerged as an alternative to staged strategy. Aim: To describe our experience of combined LAAC procedures using Watchman™ devices. Method: All patients with combined LAAC procedure using Watchman™ (WN) devices performed from 2016-2021 were included. The primary safety endpoint was a composite of periprocedural complications and adverse events during follow-up. The primary efficacy endpoint included strokes, systemic embolisms, major bleeding, and cardiovascular death. Results: Since 2016, among the 157 patients who underwent LAAC using WN devices, 16 underwent a combined strategy: 6 TEMVR (37%), 6 typical atrial flutter ablation (37%), 2 LP implantation (13%) and 2 atrial fibrillation ablation (13%). The WN device was successfully implanted in 98% and 100% for single and combined LAAC respectively (p = 0.63). Median follow-up was 13 months (IQR 25/75 3/24) in the whole cohort. Device related complications occurred in 6 out of 141 patients (4%) who underwent single LAAC and in no (0/16) patient in the combined LAAC procedure (p=ns). The procedural related complications did not differ significantly between groups (5% vs 12%, respectively in the single and combined group, p=0.1). Conclusion: Combined procedure combining LAAC using the Watchman™ devices and one other structural or electrophysiological procedure is safe and effective. Larger series are needed to confirm these results.

Background: Simultaneous atrial fibrillation (AF) catheter ablation and left atrial appendage closure (LAAC) is sometimes recommended for both rhythm control and stroke prevention. However, the advantages of intracardiac echocardiography (ICE) guidance for this combined procedure have been scarcely reported. To evaluate the clinical outcomes and safety of ICE guided LAAC within a zero-fluoroscopy catheter ablation procedure. Methods and Results:From April 2019 to April 2020, 56 patients with symptomatic AF underwent concomitant catheter ablation and LAAC. ICE with a multi-angled imaging protocol mimicking the TEE echo windows was used to guide LAAC. Successful radiofrequency catheter ablation and LAAC was achieved in all patients. Procedure-related adverse event rate was 3.6%. During the 12-month follow-up, 77.8% of patients became free of arrhythmia recurrences and oral anticoagulants were discontinued in 96.4% of patients. No ischemic stroke occurred despite two cases of device-related thrombosis versus an expected stroke rate of 4.8% based on the CHA2DS2-VASc score. The overall major bleeding events rate was 1.8%, which represented a relative reduction of 68% versus an expected bleeding rate of 5.7% based on the HAS-BLED score of the patient cohort. The incidence of iatrogenic atrial septal defect secondary to a single transseptal access dropped from 57.9% at 2 months to 4.2% at 12 months TEE follow-up. Conclusion:The combination of catheter ablation and LAAC under ICE guidance was safe and effective in AF patients with high stroke risk. ICE with our novel protocol was technically feasible for comprehensive and systematic assessment of device implantation.
