Atrial Fibrillation After Patent Foramen Ovale Closure: Incidence, Pathophysiology, and Management. J Am Heart Assoc 2024; 13:e034249. [PMID: 38639354 PMCID: PMC11179870 DOI: 10.1161/jaha.124.034249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 02/06/2024] [Indexed: 04/20/2024]
Abstract
This comprehensive review explores the incidence, pathophysiology, and management of atrial fibrillation (AF) following percutaneous closure of patent foramen ovale (PFO). Although AF is considered a common adverse event post PFO closure, its incidence, estimated at <5%, varies based on monitoring methods. The review delves into the challenging task of precisely estimating AF incidence, given subclinical AF and diverse diagnostic approaches. Notably, a temporal pattern emerges, with peak incidence around the 14th day after closure and a subsequent decline after the 45th day, mimicking general population AF trends. The pathophysiological mechanisms behind post PFO closure AF remain elusive, with proposed factors including local irritation, device-related interference, tissue stretch, and nickel hypersensitivity. Management considerations encompass rhythm control, with flecainide showing promise, and anticoagulation tailored to individual risk profiles. The authors advocate for a personalized approach, weighing factors like age, comorbidities, and device characteristics. Notably, postclosure AF is generally considered benign, often resolving spontaneously within 45 days, minimizing thromboembolic risks. Further studies are required to refine understanding and provide evidence-based guidelines.

Kasner SE, Sondergaard L, Nakum M, Gomez Montero M, Hashim M, Landaas EJ. A matching-adjusted indirect comparison of results from REDUCE and RESPECT-two randomized trials on patent foramen ovale closure devices to prevent recurrent cryptogenic stroke. J Med Econ 2024; 27:337-343. [PMID: 38373018 DOI: 10.1080/13696998.2024.2320604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 02/15/2024] [Indexed: 02/20/2024]
Abstract
AIMS Two randomized clinical trials, REDUCE and RESPECT, demonstrated that patent foramen ovale (PFO) closure in combination with antithrombotic therapy was more effective for the prevention of recurrent ischemic stroke compared with antithrombotic therapy alone. The aim of this study was to determine the relative efficacy and safety of the PFO closure devices used in REDUCE (HELEX and CARDIOFORM Septal Occluders) compared with the device used in RESPECT (Amplatzer PFO Occluder). METHODS An unanchored matching-adjusted indirect comparison (MAIC) of the PFO closure arms of the REDUCE and RESPECT trials was performed using patient-level data from REDUCE weighted to match baseline characteristics from RESPECT. Comparisons of the following outcomes were made between the devices assessed in the trials: risk of recurrent ischemic stroke; recurrent ischemic stroke one year after randomization; any serious adverse event (SAE) related to the procedure or device; and atrial fibrillation or atrial flutter as an SAE related to the procedure or device. RESULTS After conducting the MAIC, baseline characteristics were well-matched between the two trials. Compared to RESPECT, PFO closure using the devices from REDUCE resulted in a hazard ratio of 0.46 (95% confidence interval [CI] 0.15-1.43; p = 0.17) for the risk of recurrent stroke. For the recurrence of stroke after one year, SAE related to the procedure or device, and atrial fibrillation or atrial flutter as SAE related to the procedure or device, the MAIC resulted in a rate difference of -0.68 (95%CI -2.06 to 0.70; p = .34), -1.29 (95%CI -3.82 to 1.25; p = .32), and -0.19 (95%CI -1.16 to 0.78; p = .71), respectively. These findings were consistent across scenario analyses. CONCLUSIONS This MAIC analysis found no statistically significant differences in efficacy and safety outcomes between PFO closure with the HELEX and CARDIOFORM Septal Occluders versus the Amplatzer PFO Occluder, as used in the REDUCE and RESPECT trials.

Pharmgenomics Pers Med 2023; 16:303-312. [PMID: 37051559 PMCID: PMC10083142 DOI: 10.2147/pgpm.s404663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Accepted: 03/31/2023] [Indexed: 04/07/2023] Open
Abstract
Background The apolipoprotein E (ApoE) genetic variation may contribute to the development of Cerebral Infarction (CI). Serum lipid levels are known risk factors for CI, but the effect of the ApoE gene polymorphism on lipid metabolism remains unclear. This retrospective cohort study was designed to determine the role of ApoE genotypes in CI risk and the relationships between ApoE gene polymorphism and serum lipid levels among the population of northwest China. Patients and Methods 517 CI patients and 517 non-CI controls were enrolled in the study. Polymerase chain reaction and hybridization were utilized to determine the ApoE gene polymorphisms. Results The ε3/ε4 genotype and ε4 allele frequency were significantly higher in CI patients than in controls. When stratified by age and sex, statistically significant differences in the distribution and frequency of the ε3/ε4 genotype and ε4 allele were found between patients and controls. Compared to ε2 carriers, ε4 carriers had significantly lower ApoE levels and higher low-density lipoprotein cholesterol (LDL-C), ApoB and ApoB/ApoA-I levels in both two groups. Additionally, control participants with ε4 carriers had significantly higher levels of lipoprotein and total cholesterol (TC) levels than ε2 carriers, while CI patients with ε4 carriers had a significantly lower level of ApoA-I. After adjusting for other established risk factors, drinking, hypertension, lipoprotein, triglycerides (TG) and ε4 allele were significant independent risk factors for CI, which was shown to be associated with a nearly two-fold CI risk. Conclusion This study demonstrated that ε4 allele is independent risk factors for CI among patients in Northwest China. ApoE polymorphism was associated with CI, which was partly mediated through blood lipids and may also be mediated through non-lipid pathways. These data might be of great clinical significance in individualized preventive and therapeutic strategies.

Kolokathis K, Thomopoulos C, Tsioufis K. Net clinical benefit of PFO closure versus medical treatment in patients with cryptogenic stroke: A systematic review and meta-analysis. Hellenic J Cardiol 2022; 70:46-52. [PMID: 36584788 DOI: 10.1016/j.hjc.2022.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 12/02/2022] [Accepted: 12/23/2022] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND The ideal treatment for patent foramen ovale (PFO) in patients with cryptogenic stroke remains controversial and is being evaluated. The objective of this study was to evaluate the net clinical benefit (NCB) between PFO closure and medical treatment. METHODS We searched three electronic databases from inception until January 2022. The primary outcomes were the NCB-1, defined as the cumulative incidence of stroke, major bleeding, atrial fibrillation/flutter, and serious procedural or device complications; the NCB-2 and NCB-3 were defined as NCB1 but using a weighted factor of 0.5 and 0.25 for atrial fibrillation/flutter events, respectively. We also evaluated each component outcome of NCB as a secondary outcome. Risk ratios (RR) and 95% confidence intervals (CI) of each outcome were calculated (random-effects model). RESULTS Our analysis included six RCTs (n = 3750 patients). The rates of NCB-1, NCB-2, and NCB-3 were not different between PFO closure and medical treatment. The heterogeneity between trials was low to moderate. Stroke showed a significant relative decrease of 44% (95% CI, 21-60%), favoring the PFO closure arm. Atrial fibrillation/flutter increased by 4.04 times (95% CI, 1.57-8.89) in the PFO closure compared with the medical treatment group. In a meta-regression analysis, the reduction in NCB-1 with PFO closure increased as the proportion of patients treated with the Amplatzer device increased (p = 0.02), and the reduction in NCB-1, NCB-2, and NCB-3 with PFO closure increased as the proportion of patients treated with substantial PFO size increased (p = 0.03). CONCLUSION The NCB between PFO closure and medical treatment was not different, suggesting individualized treatment to maximize benefit.

Atrial fibrillation screening on systematic ambulatory electrocardiogram monitoring after percutaneous patent foramen ovale closure: A prospective study. IJC HEART & VASCULATURE 2021; 37:100919. [PMID: 34849392 PMCID: PMC8609133 DOI: 10.1016/j.ijcha.2021.100919] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 11/02/2021] [Accepted: 11/14/2021] [Indexed: 11/17/2022]
Abstract
Incidence of atrial fibrillation (AF) following patent foramen ovale (PFO) closure is low (<5%) AF occurs early following PFO closure and is not associated with an increased risk of embolic complications. Symptomatic atrial ectopic beats are frequent following PFO closure and not associated with AF.
Background Increased risk of new-onset atrial fibrillation (AF) after patent foramen ovale (PFO) closure was observed in randomized trials without however systematic AF screening. We aimed to evaluate the incidence of AF within 6-month following PFO closure with serial 24-hour ambulatory electrocardiogram (AECG) monitoring. Methods All patients undergoing PFO closure were prospectively included in 2 centers. AF was defined as irregular rhythm without discernible P waves > 30 s on AECG at day 0, 1-month and 6-month follow-up. Primary endpoint was the incidence of AF within the study period. Secondary endpoints evaluated clinical outcomes within 6-month follow-up. Results Between February 2018 and March 2019, 62 patients underwent PFO closure including 40 male (64.5%) with a mean age of 48 ± 9.5. Atrial septal aneurysm was observed in 37 patients (64.9%), 57 patients (91.9%) received an Amplatzer Occluder device (Abbott Vascular) and 5 (8.1%) an Occlutech device (Occlutech). After a mean follow-up of 7.7 ± 2.8 months, new-onset AF occurred in 3 patients (4.8%), all within the first month following PFO closure, including one per-procedural, all were asymptomatic and paroxysmal. Two patients with AF (3.2%) required chronic oral anticoagulant therapy. No adverse outcomes occurred at follow-up. No predictive factors of AF were highlighted. A total of 16 patients (25.8%) reported palpitations without AF on the AECGs. Conclusion In highly selected patients, incidence of AF, evaluated with 3 systematic 24-hour AECG within 6-month following PFO closure, was low (<5%). Always paroxysmal, AF occurred within the first month after the procedure and was not associated with adverse outcomes.

Abstract
OBJECTIVES To describe the occurrence of postprocedural atrial fibrillation (AF) among patients with cryptogenic stroke undergoing patent foramen ovale (PFO) closure in the REDUCE clinical study and analyze for potential risk factors for the development of postprocedural AF. BACKGROUND AF is an adverse event that might potentially counterbalance the stroke prevention benefit from PFO closure. Data on AF after transcatheter PFO closure are sparse. METHODS We evaluated data from patients having PFO closure (Gore HELEX or Gore Cardioform Septal Occluder) in the REDUCE clinical trial (n = 408) in at post hoc explorative analysis. Median follow-up was 5.0 years. RESULTS AF occurred in 30 patients (7.4%) after PFO closure with a total of 34 AF events. Most were reported as non-serious (68%), detected within 45 days post-procedure (79%), and resolved within 2 weeks of onset (63%). One subject with AF had recurrent stroke. Postprocedural AF occurred more frequently among subjects with higher age and large device sizes. Male sex was the only independent predictor of postprocedural AF. We found no association between the type of occluder (HELEX or Gore Cardioform Septal Occluder) or PFO anatomical characteristics and post-procedural AF. CONCLUSION In the REDUCE clinical study, postprocedural atrial fibrillation was mostly early onset, transient and with no later recurrence. Postprocedural AF occurred more frequently among patients with higher age and larger devices. Male sex was the only independent predictor of postprocedural AF.
