Radiofrequency ablation (RFA) is an important therapeutic modality for atrial fibrillation (AF), widely utilized in clinical practice due to its safety and significant efficacy. This case report describes a unique instance of a patient developing AEF following AF ablation, accompanied by ischemic stroke and myocardial infarction.
It can be associated with reduced quality of life and complications such as heart failure and stroke. Atrial fibrillation is the most prevalent arrhythmia with a lifetime risk of nearly 30%. Pulmonary vein isolation (PVI) is the most effective treatment for rhythm control. It has initially been performed with fluoroscopic catheter guiding.
Outcomes of ablation with the FARAPULSE PFA System – a nonthermal treatment in which electric fields selectively ablate heart tissue – will be compared to outcomes following use of anti-arrhythmic drug (AAD) therapy, which is commonly prescribed for patients living with persistent AF. The company now anticipates U.S. Circulation.
Titled "Real-world Data Affirms Safety and Effectiveness of Low/Zero Fluoroscopy Atrial Fibrillation Ablation," the study was presented as a late-breaker at the 29th Annual International AF Symposium. Biosense Webster's zero fluoroscopy workflow is the first and only such workflow available in a radiofrequency (RF) cardiac ablation device.
Methods All patients undergoing convergent PsAF ablation at our centre were retrospectively analysed. The Atricure Epi-Sense® system was used to perform surgical radiofrequency ablation of the LA posterior wall followed by endocardial ablation. All were longstanding persistent. There were no endocardial procedure complications.
What is the incidence of the embolic and bleeding complications in relation to pre- and post- periprocedure antithrombotic regimens in patients undergoing ventricular arrhythmia radiofrequency ablation (RFA)?
Objective Catheter ablation of atrial fibrillation effectively reduces symptomatic burden. However, its long-term effect on mortality and stroke is unclear. We investigated if patients with atrial fibrillation who undergo catheter ablation have lower risk for all-cause mortality or stroke than patients who are managed medically.
In this study we investigated the impact of ABC stroke score on the recurrence of paroxysmal atrial fibrillation (PAF) following radiofrequency catheter ablation (RFCA).
This condition can lead to various complications, including stroke and heart failure, making it essential to understand its causes, symptoms, and AFib treatment options. Complications Associated with AFib One of the most severe complications of untreated AFib is stroke. If a clot travels to the brain, it can result in a stroke.
Left atrial appendage closure (LAAC) in patients at moderate to high risk for stroke who were undergoing catheter atrial fibrillation (AFib) ablation resulted in significantly less bleeding compared with oral anticoagulation, based on findings from the OPTION trial presented at AHA 2024 and simultaneously published in NEJM.

Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups. vs 81.5%, p=0.02). 95% CI 0.19
Stroke) The American Society. (MedPage Today) -- Magnesium's hemostatic effects in intracerebral hemorrhage were supported by reduced hematoma expansion in FAST-MAG participants who achieved higher serum magnesium levels with magnesium treatment.
Strokes and silent ischemia remain a serious complication of atrial fibrillation catheter ablation (AFCA). This is mainly due to extensive ablation lesions in the left atrium that create large areas of endothelial injury that produces prothrombotic states during and after AFCA.
IntroductionAtrial fibrillation (AF) is a prevalent cardiac arrhythmia and a significant contributor to cardioembolic stroke, a condition closely linked to cognitive decline. However, research reveals that AF itself is independently associated with an increased risk of cognitive impairment.
ResultsWe identified 11 significant intervention-requiring complications associated with LAAC with or without Ablation procedure. The pericardial effusion or tamponade likely resulted from damage to the atrial appendage during LAAC device insertion.

Abbott Announces First Global Procedures in a Clinical Trial of its Volt Pulsed Field Ablation System to Treat Patients with Abnormal Heart Rhythms A Dietary Supplement Leads to Remarkable Regression in Atherosclerotic Lesions 2.
Atrial fibrillation (AF) affects millions worldwide, leading to significant healthcare costs, stroke, and heart failure. The most common treatment option, radiofrequency (RF) ablation, has limitations including poor contact and suboptimal thermal coupling.
The 2023 ACC/AHA guidelines recommend anticoagulation for three months post-catheter ablation for atrial fibrillation (AF) and lifelong anticoagulation for patients with CHA2DS2VASc score 2.1
The coexistence of these conditions can further induce structural changes and result in worsened outcomes such as stroke, HF decompensation, poorly controlled AF, and mortality [1]. However, the real-world data on the impact of AF ablation in heart failure with preserved ejection fraction (HFpEF) is not well-established.
ABSTRACT Background Catheter ablation improves symptoms and quality of life in atrial fibrillation patients, but its effect on adverse cardiovascular outcomes and mortality remains uncertain. that ablation is superior in reducing adverse cardiovascular outcomes and mortality, respectively.
Patients suffering from heart rhythm disorders are now being successfully treated with robotic ablation procedures using this advanced technology, and Hospital Santa Maria della Pietà is the first hospital in Italy to adopt the cutting-edge Genesis Robotic Magnetic Navigation (RMN) system.
Left atrial appendage occlusion device (LAAOD) has emerged as an alternative to anticoagulation for stroke prevention in NVAF patients. AF ablation and LAAOD implant done concomitantly has not been adequately studied. Early non randomized data suggests this combination procedure can be done safely.
Robotic Magnetic Navigation introduces the benefits of robotic precision and safety to cardiac ablation, a common minimally invasive procedure to treat arrhythmias. When left untreated, arrhythmias may significantly increase the risk of stroke, heart failure, and sudden cardiac arrest.
ABSTRACT Introduction Pulmonary vein isolation (PVI) by cryoballoon ablation (CBA) is considered an effective primary strategy for early persistent atrial fibrillation (AF). However, data regarding CBA for long-standing persistent AF (PeAF) are limited. We evaluated the efficacy and safety of CBA for long-standing PeAF compared to PeAF.
Abstract Introduction Despite advanced ablation strategies and major technological improvements, treatment of persistent atrial fibrillation (AF) remains challenging and the underlying pathophysiology is not fully understood. Randomized studies are necessary to evaluate long-term efficacy of dispersion-guided ablation using AI.
Stroke, Volume 56, Issue Suppl_1 , Page ADP26-ADP26, February 1, 2025. The function of these novel RNAs within the post-stroke brain remains virtually unexplored. Select eSINE-RNAs were ablated via intracerebroventricular injection of antisense oligonucleotides followed by 1h MCAO and 24h reperfusion.
ABSTRACT Introduction Left atrium epicardial adipose tissue (LA-EAT) is an atrial cardiomyopathy marker associated with ischemic stroke. This study investigated the effect of EAT on the risk of SCI after atrial fibrillation catheter ablation (AFCA). However, the relationship between EAT and silent cerebral infarcts (SCI) is unclear.
If untreated, AFib can lead to or exacerbate heart failure, and it significantly increases a person’s risk of stroke. Catheter ablation was given the highest Class 1 treatment recommendation for appropriately selected patients, including those with heart failure with reduced ejection fraction.
