Special Issue Information

Dear Colleagues,

Atrial fibrillation (AF) is being increasingly recognized as the cardiovascular epidemic of the 21st century, impacting millions globally. The clinical and economic burden of AF is anticipated to increase with the ongoing population aging and rise in prevalence of risk factors such as obesity, hypertension, sleep apnea and others. Given its association with an increased risk of stroke, heart failure and mortality, an early diagnosis and effective management of AF are paramount. Over the past decade, significant advancements have been achieved in the field of AF, from innovative diagnostic tools that facilitate early detection, to changes in the paradigm of AF management, favoring patient-tailored rhythm control management to improve patient outcomes. In parallel, cutting-edge technologies that revolutionized AF management procedures, including novel electro-anatomical mapping systems, advanced ablation catheters and techniques and left atrial appendage occlusion devices, have been transforming patient care in the last two decades. This Special Issue aims to explore the most recent advancements in the diagnosis and treatment of atrial fibrillation. Researchers in the field of atrial fibrillation are encouraged to submit original articles or reviews to this Special Issue. With contributions from leading experts, this Special Issue intends to provide a valuable resource for clinical researchers and doctors involved in atrial fibrillation care, paving the way for improved outcomes for patients with this challenging arrhythmia.

Background/Objectives: Atrial fibrillation (AF) and flutter (AFL) are the most common cardiac arrhythmias worldwide. Cardiovascular complications are a common manifestation of acute and post-acute COVID-19 infection. We aimed to analyze the nationwide trends in clinical characteristics and outcomes of patients hospitalized for AF/AFL before and during the COVID-19 outbreak in the U.S. Methods: This study is a retrospective analysis of patients, aged 18 and older, hospitalized for AF/AFL in the U.S. between 2016 and 2020. We drew data from the National Inpatient Sample (NIS) database. Baseline sociodemographic and clinical data, as well as outcomes including stroke, acute coronary syndrome (ACS), and mortality, were analyzed. Multivariable analysis was performed to identify independent associations between the different clinical and demographic characteristics and the composite endpoint of Mortality/ACS/Stroke. Results: An estimated total of 2,163,699 hospitalizations for AF/AFL were identified. The hospitalization volume between 2016 and 2019 was stable, averaging 465,176 a year, followed by a significant drop to 302,995 in 2020. Patients’ median age was 72 years (IQR 62–80), 50.9% were male, and 81.5% were white. The composite endpoint steadily increased from 6.5% in 2016 to 11.8% in 2020 (Ptrend < 0.001). In a multivariable regression analysis, age > 75 (OR: 1.35; 95% CI 1.304–1.399, p < 0.001), ischemic heart disease (OR: 1.466; 95% CI: 1.451–1.481; p < 0.001), and chronic kidney disease (OR: 1.635; 95% CI: 1.616–1.653; p < 0.001) were associated with the composite endpoint. COVID-19 was associated with the composite endpoint outcome in the year 2020 (OR: 1.147; 95% CI: 1.037–1.265; p = 0.007). Conclusions: Hospitalization for AF/AFL dropped significantly during the first year of the COVID-19 pandemic outbreak, possibly due to patients’ avoidance of hospital visits. The composite endpoint of Mortality/ACS/Stroke uptrended significantly during the study period. COVID-19 was shown to be independently associated with the adverse composite outcome Mortality/ACS/Stroke. Full article

Introduction: Catheter ablation (CA) for atrial fibrillation (AF) has been proven to have the highest efficacy in maintaining sinus rhythm. Several studies have proposed different scores for predicting post-procedural success, but most have not been validated in prospective cohorts. Further research is required to determine the optimal formulae. Purpose: This study aimed to identify independent predictors of AF recurrence after CA and develop a composite score. Methods: Consecutive patients with persistent and paroxysmal AF who underwent CA were retrospectively analyzed. The independent predictors of recurrence were used to create a new predictive score. Results: The cohort included 263 patients with a follow-up of 37.6 ± 23.4 months. Persistent AF, f-waves < 0.1 mV, indexed left atrium volume, the presence of type 2 diabetes, and smaller height were independent predictors of recurrence and were used to create a new scoring model, VAT-DHF (V = Volume, AT = AF Type, D = Diabetes, H = Height, F = f waves). The ROC curve for this new score showed an AUC of 0.869, p < 0.0001, 95% CI [0.802–0.936], while those for APPLE and CHA2DS2-VASc showed an AUC of 0.765, 95% CI [0.637–0.893] and an AUC of 0.655, 95% CI [0.580–0.730], respectively. Patients who had a VAT-DHF score between 0 and 3.25, 3.25 and 6, and ≥6, had success rates of 95.7%, 76.3%, and 25% (p < 0.0001), respectively. Conclusions: The novel VAT-DHF score is easy to calculate and may be a useful clinical tool for identifying patients with a low, intermediate, or high risk of AF recurrence after CA. Full article

Aims: The discontinuation of oral anticoagulants (OACs) remains as a significant concern in the management of atrial fibrillation (AF). The discontinuation rate may vary depending on management strategy, and physicians may also discontinue OACs due to concerns about patient satisfaction with their care. We aimed to assess the incidence of OAC discontinuation and its relationship to patients’ health in an outpatient AF registry. Methods and Results: From a multicenter registry for newly recognized AF patients (n = 3313), we extracted 1647 (49.7%) patients with OACs and a CHA2DS2-Vasc score of ≥2. Discontinuation was defined as sustained cessation of OACs within a 1-year follow-up. We examined predictors associated with discontinuation and its relations to health status defined by the AFEQT questionnaire. Of the 1647 patients, 385 (23.6%) discontinued OACs after 1 year, with discontinuation rates varying across treatment strategies (15.3% for catheter ablation, 4.9% for rhythm control with antiarrhythmic drugs, and 3.0% for rate control). Successful rhythm control was associated with discontinuation in the catheter ablation (OR 6.61, 95% CI 3.00–14.6, p < 0.001) and antiarrhythmic drugs (OR 6.47, 95% CI 2.62–15.9, p < 0.001) groups, whereas the incidence of bleeding events within 1 year was associated with discontinuation in the rate control group. One-year AFEQT scores did not significantly differ between patients who discontinued OACs and those who did not in each treatment strategy group. Conclusions: OAC discontinuation was common among AF patients with significant stroke risk but varied depending on the chosen treatment strategy. This study also found no significant association between OAC discontinuation and patients’ health status. Full article

Left atrial appendage closure (LAAC) is an alternative approach to anticoagulants. Nonetheless, data regarding the outcomes of LAAC procedures in patients with thrombocytopenia remain lacking. The primary objective was to determine the incidence of the composite endpoint comprising ischemic stroke, intracranial hemorrhage, major bleeding, and cardiac cause of death among patients with atrial fibrillation (AF) and thrombocytopenia who were either undergoing LAAC or receiving oral anticoagulants. The secondary endpoint was the determination of total mortality. Data from a prospective, single-center registry of patients undergoing LAAC procedures were analyzed. A subset of 50 consecutive patients with thrombocytopenia were selected. Thrombocytopenia was defined as a thrombocyte count below 150,000. Subsequently, from patients hospitalized with AF receiving oral anticoagulants, 50 patients were further chosen based on propensity score matching, ensuring comparability with the study group. The primary endpoint occurred in 2% of patients in the LAAC group and 10% of patients in the non-LAAC group (p = 0.097). Additionally, a significant difference was noted in the occurrence of the secondary endpoint, which was observed in 0% of patients in the LAAC group and 10% of patients in the non-LAAC group (p = 0.025). In patients with thrombocytopenia the LAAC procedure improves prognosis compared with continued anticoagulant treatment. Full article

Left atrial appendage closure (LAAC) is a crucial intervention for stroke prevention in patients with non-valvular atrial fibrillation who are unsuitable for long-term anticoagulation. Amulet and Watchman are the most implanted devices worldwide for performing LAAC, and the aim of this review is to provide a comprehensive comparison focusing on their efficacy, safety, and short- and long-term outcomes. The Watchman device, the first to gain FDA approval, has been extensively studied and demonstrates significant reductions in stroke and systemic embolism rates. The Amulet device, a newer alternative, promises enhanced design features for more efficient appendage sealing. Current data highlight that both devices offer similar efficacy and safety for LAAC. While the two devices differ in terms of intraprocedural complication rates, they offer similar short- to long-term outcomes in terms of peri-device leaks, device-related thrombosis, and mortality. Both devices are indicated for patients who are unable to tolerate OAC, given their similar risk and safety profiles. Newer clinical studies are directed at establishing the efficacy of both devices as the primary method for stroke prevention in AF as an alternative to OAC. Full article
