Filter by:Atrial fibrillation (AF) is associated with impaired cognitive function (CogF) and/or dementia, but it is unclear whether rhythm control of AF improves CogF or brain perfusion. The hypothesis is rhythm control of AF improves CogF by increasing brain perfusion with hemodynamic amelioration compared to AF state. We will randomize the patients with persistent AF to rhythm control group and rate control group, and check baseline and 3rd month cognitive function (K-MOCA score) and brain perfusion CT. K-MOCA score and brain perfusion CT findings will be compared between rhythm control group and rate control group of persistent AF.
The study aims to compare the results of pulmonary vein isolation (PVI) with a single technology approach in patients suffering from paroxysmal atrial fibrillation (PAF) with patients who have persistent AF of less than 3 months. Many studies have shown that electrical reconnection of the pulmonary veins following the index procedure can occur in up to 40% of targeted veins leading to a recurrence of PAF. Endoscopically guided laser ablation utilising the HeartLight system (CardioFocus Inc., USA) has been shown to be safe and effective and has also shown promising rates of durable isolation compared to point by point radio frequency techniques. However, the impact of employing this technique for patients with persistent AF has not yet been reported. The study hypothesis is that there will be no statistically significant difference between the results of PVI in the two groups of patients.
The aim of this trial is to evaluate the effect of acupuncture on prevention of atrial fibrillation (AF) recurrence after electrical cardioversion (EC) for persistent AF patients resistant to the antiarrhythmic drugs (AADs).
The investigators have conducted a prospective, double-blind, randomized study to assess the comparative safety and efficacy of two different ablation strategies, PVI plus linear lesions (LL) plus botulinum toxin injection versus PVI plus linear lesions (LL), in patients with persistent or longstanding persistent AF. Results were assessed with the use of an implanted monitoring device (IMD).
The investigators have conducted a prospective, double-blind, randomized study to assess the comparative safety and efficacy of two different treatment strategies, PVI only versus PVI plus BT injection, in patients with persistent and paroxysmal AF. Results were assessed after follow-up of at least 1 years with the use of an implanted monitoring device (IMD).
This study aims to examine the long-term success rate of catheter ablation in non-paroxysmal atrial fibrillation patients using different ablation strategies such as : (i) pulmonary vein antrum isolation (PVAI) + isolation of left atrial posterior wall, (ii) PVAI plus scar homogenization, (iii) PVAI plus isolation of posterior wall plus ablation of non-PV triggers [ PVAI: Pulmonary Vein Antrum Isolation Non-PV triggers: Triggers arising from sites other than pulmonary veins]
The purpose of the study is to assess combining AF ablation, with AV node ablation and pacemaker implantation for patients suffering with 'irregular heartbeats' or atrial fibrillation. The study will last 13 months.
Experimental data suggest that angiotensin II-antagonists reduce the atrial expression of prothrombotic adhesion molecules and oxidative stress parameters. The present study is designed to investigate the effects on angiotensin II-antagonist irbesartan to reduce the amounts of circulating oxidative stress markers and adhesion molecules in patients with persistent atrial fibrillation.
