Abstract
Atrial fibrillation (AF) is associated with an increased risk of stroke and systemic embolism, and the left atrial appendage (LAA) has been identified as a principal source of thromboembolism in these patients. While oral anticoagulation is the current standard of care, LAA closure (LAAC) emerges as an alternative or complementary treatment approach to reduce the risk of stroke or systemic embolism in patients with AF. Moderate-sized randomized clinical studies have provided data for the efficacy and safety of catheter-based LAAC, largely compared with vitamin K antagonists. LAA device iterations, advances in pre- and peri-procedural imaging, and implantation techniques continue to increase the efficacy and safety of LAAC. More data about efficacy and safety of LAAC have been collected, and several randomized clinical trials are currently underway to compare LAAC with best medical care (including non-vitamin K antagonist oral anticoagulants) in different clinical settings. Surgical LAAC in patients with AF undergoing cardiac surgery reduced the risk of stroke on background of anticoagulation therapy in the LAAOS III study. In this review, we describe the rapidly evolving field of LAAC and discuss recent clinical data, ongoing studies, open questions, and current limitations of LAAC.

Left atrial appendage closure in very elderly patients in the French National Registry. Heart 2024; 110:245-253. [PMID: 37813560 DOI: 10.1136/heartjnl-2023-322871] [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: 04/23/2023] [Accepted: 08/19/2023] [Indexed: 10/17/2023] Open
Abstract
OBJECTIVE Left atrial appendage closure (LAAC) is recommended to decrease the stroke risk in patients with atrial fibrillation and contraindications to anticoagulation. However, age-stratified data are scarce. The aim of this study was to provide information on the safety and efficacy of LAAC, with emphasis on the oldest patients. METHODS A nationwide, prospective, multicentre, observational registry was established by 53 French cardiology centres in 2018-2021. The composite primary endpoint included ischaemic stroke, systemic embolism, and unexplained or cardiovascular death. Separate analyses were done in the groups <80 years and ≥80 years. RESULTS Among the 1053 patients included, median age was 79.7 (73.6-84.3) years; 512 patients (48.6%) were aged ≥80 years. Procedure-related serious adverse events were non-significantly more common in octogenarians (7.0% vs 4.4% in patients aged <80 years, respectively; p=0.07). Despite a higher mean CHA2DS2-VASc score in octogenarians, the rate of thromboembolic events during the study was similar in both groups (3.0 vs 3.1/100 patient-years; p=0.85). By contrast, all-cause mortality was significantly higher in octogenarians (15.3 vs 10.1/100 patient-years, p<0.015), due to a higher rate of non-cardiovascular deaths (8.2 vs 4.9/100 patient-years, p=0.034). The rate of the primary endpoint was 8.1/100 patient-years overall with no statistically significant difference between age groups (9.4 and 7.0/100 patient-years; p=0.19). CONCLUSION Despite a higher mean CHA2DS2-VASc score in octogenarians, the rate of thromboembolic events after LAAC in this age group was similar to that in patients aged <80 years. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry (NCT03434015).

Clin Cardiol 2024; 47:e24169. [PMID: 37804320 PMCID: PMC10766124 DOI: 10.1002/clc.24169] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Revised: 09/19/2023] [Accepted: 09/26/2023] [Indexed: 10/09/2023] Open
Abstract
BACKGROUND Catheter ablation (CA) combined with left atrial appendage closure (LAAC) has emerged as a promising method to relieve symptoms while reducing the incidence of stroke in selected high-risk patients with atrial fibrillation (AF). HYPOTHESIS We aimed to investigate the clinical outcomes of combined CA and LAAC in elderly patients. METHODS A total of 316 patients with symptomatic drug-refractory AF who underwent combined CA and LAAC between January 2016 and December 2020 were retrospectively included. Baseline characteristics, periprocedural complications, and clinical events during follow-up were recorded and compared between patients aged ≥ 75 years (n = 66) and <75 years (n = 250). RESULTS Pulmonary vein isolation and satisfactory LAAC were achieved in all patients. No patients experienced death or stroke/transient ischemic stroke periprocedurally. After a median follow-up of 12.2 (6.7-24.4) months and 11.9 (5.5-23.6) months, the rate of sinus rhythm maintenance was comparable between the two groups (≥75 years: 78.8% vs. <75 years: 80.8%; log-rank test, p = 0.674). The median follow-up periods for clinical outcomes were 27.9 (9.3-44.8) months and 25.2 (10.8-45.7) months, respectively. In patients aged ≥ 75 years, one suffered ischemic stroke, and one experienced major bleeding event. In patients aged < 75 years, four had ischemic stroke, and eight had major bleeding events. Two patients aged < 75 years died during follow-up, while none of the patients aged ≥ 75 years died. CONCLUSIONS Combining CA and LAAC was feasible, safe and effective in elderly patients with AF.

Diagnostics (Basel) 2022; 12:diagnostics12123174. [PMID: 36553181 PMCID: PMC9777302 DOI: 10.3390/diagnostics12123174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/08/2022] [Accepted: 12/10/2022] [Indexed: 12/23/2022] Open
Abstract
Background: Left atrial appendage closure (LAAC) is an established therapy for patients with atrial fibrillation (AF); however, there is a limited understanding of LAAC in elderly patients (≥75 years old). We conducted a meta-analysis to investigate the procedural complications and long-term outcomes after LAAC in the elderly versus the non-elderly. Methods: We screened PubMed, EMBASE, Cochrane Library, and Web of Science. Procedural endpoints of interest included successful implantation LAAC rates, in-hospital mortality, major bleeding events, pericardial effusion/tamponade, stroke, and vascular access complications related to LAAC. Long-term outcomes included all-cause mortality, major bleeding events, and stroke/transient ischemic attack (TIA) during follow-up. Results: Finally, 12 studies were included in the analysis; these included a total of 25,094 people in the elderly group and 36,035 people in the non-elderly group. The successful implantation LAAC rates did not differ between the groups, while the elderly patients experienced more periprocedural mortality (OR 2.62; 95% CI 1.79−3.83, p < 0.01; I2 = 0%), pericardial effusion/tamponade (OR 1.39; 95% CI: 1.06−1.82, p < 0.01; I2 = 0%), major bleeding events (OR 1.32; 95% CI 1.17−1.48, p < 0.01; I2 = 0%), and vascular access complications (OR 1.34; 95% CI 1.16−1.55, p < 0.01; I2 = 0%) than the non-elderly patients. The long-term stroke/TIA rates did not differ between the elderly and the non-elderly at least one year after follow-up. Conclusions: Even though successful implantation LAAC rates are similar, elderly patients have a significantly higher incidence of periprocedural mortality, major bleeding events, vascular access complications, and pericardial effusion/tamponade after LAAC than non-elderly patients. The stroke/TIA rates did not differ between both groups after at least one-year follow-up.

Abstract
The mean age in clinical trials of percutaneous left atrial appendage occlusion (LAAO) has been <75 years. We aimed to better understand the safety of LAAO in older patients. National Inpatient Sample and International Classification of Diseases, Tenth Revision codes were used to identify patients with atrial fibrillation who underwent LAAO during the years 2016-2018. Patients were grouped by age <75 and ≥75 years. Baseline characteristics; length of stay; cost; hospital mortality; and other adverse events, including hematoma, vascular complications, perforation/tamponade, and stroke/ transient ischemic attack, were compared for the 2 groups. A total of 6,877 patients were identified, of whom 4,160 (60.4%) were aged ≥75 years. Length of stay and hospitalization costs were similar for the 2 groups. There were 10 deaths in patients aged ≥75 years and 1 death in patients aged <75 years (p = 0.059). The incidence of perforation/tamponade was 1.3% in patients aged ≥75 years versus 0.6% for those <75 years (p = 0.008). This difference persisted on multivariate analysis (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.01 to 3.07). The risk of perforation/tamponade was also higher in female patients (OR 2.74, 95% CI 1.63 to 4.59). There was a trend toward higher combined procedure-related adverse events (OR 1.46, 95% CI 0.99 to 2.15) in patients ≥75 years. There was no difference in the individual components of hematoma, vascular complication, and stroke/transient ischemic attack between both groups. In conclusion, percutaneous LAAO was associated with a higher risk of perforation and tamponade in older patients, particularly women.

Abstract
The prevalence of atrial fibrillation (AF) is increasing as the population ages. AF treatment-related complications also increase markedly in older adults (defined as ≥75 years of age for this review). The older AF population has a high risk of stroke, bleeding, and death. Syncope and fall-related injuries are the most common reasons for nonprescription of oral anticoagulation (OAC), and are more common in older adults when OACs are used with antiarrhythmic drugs. Digoxin may be useful for rate control, but associations with increased mortality limit its use. Beyond rate and rhythm control considerations, stroke prophylaxis is critical to AF management, and the benefits of direct OACs, compared with warfarin, extend to older adults. Invasive procedures such as AF catheter ablation, pacemaker implantation/atrioventricular junction ablation, and left atrial appendage occlusion may be useful in appropriately selected cases. However, older adults have generally been under-represented in clinical trials.

Abstract
INTRODUCTION Atrial fibrillation (AF) is the most common cardiac sustained arrhythmia, whose incidence and prevalence increase with age, representing a significant burden for health services in western countries. Older people contribute to the vast majority of patients affected from AF. EVIDENCE ACQUISITION Although oral anticoagulant therapy represents the cornerstone for the prevention of ischemic stroke and its disabling consequences, several other interventions - including left atrial appendage occlusion (LAAO), catheter ablation (CA) of AF, and rhythm control strategy (RCS) - have proved to be potentially effective in reducing the incidence of AF-associated clinical complications. Scientific literature focused on the three items will be discussed. EVIDENCE SYNTHESIS Practical treatment of older AF patients is presented, including approach and management of patients with geriatric syndromes, selection of the most appropriate individualized drug treatment, clinical indications and potential clinical benefit of LAAO and CA in selected older AF patients. CONCLUSIONS Older people carry the greatest burden of AF in real world practice. Within a shared decision making process, the patient centered approach need to be put in the context of a comprehensive assessment, in order to gain maximal net clinical benefit and avoid futility or harm.
