Filter by:This study aims to determine whether increasing atrial base rate pacing to achieve at least 75-80% atrial pacing in patients with sick sinus syndrome undergoing the implementation of dual-chamber pacemaker can be useful to prevent or decrease the atrial fibrillation during 6 months follow-up duration.
A prospective, multicenter, interventional study to collect confirmatory evidence on the safety and effectiveness of the TactiCath® percutaneous ablation catheter in the post approval setting for the treatment of symptomatic paroxysmal atrial fibrillation using contact force assisted irrigated radiofrequency ablation.
This is a pilot study designed to investigate the effectiveness of the nMARQ Pulmonary Vein Isolation system in the treatment of Paroxysmal Atrial Fibrillation (AF) at different ablation settings. AF is a common condition which causes a fast and erratic heartbeat. There are estimated to be 50,000 new cases diagnosed per year in the UK. The fast heart beat can cause symptoms such as palpitations, lightheadedness, chest pains, shortness of breath and fatigue. Catheter ablation is a technique used for the control of AF. In this procedure a catheter (a long thin wire) is passed into the chambers of the heart via a large blood vessel in a leg. The tip of the catheter can destroy tiny sections of heart tissue that may be the source or trigger of the abnormal electrical impulses. One of the challenges of AF ablation is to maximize success rates, as such there is currently rapid advances in technology to carry out this procedure. Different catheters exist which deliver this energy in different ways. This study uses one such system to perform this procedure. It is called the nMARQ system for Pulmonary Vein Isolation produced by Biosense Webster. Currently this system is used in practice in the UK for patients with this medical condition. What we seek to research is when ablating what is the optimum setting to perform ablation at. There is currently no data to guide best clinical practice in this area.
This study investigates impact of adenosine versus AF inducibility and subsequent termination on the acute and long-term outcome of paroxysmal AF ablation.
The One Freeze study is a prospective multi-center randomized controlled trial to assess the safety and efficacy of one vs. two cryoablations per pulmonary vein for the treatment of atrial fibrillation.
EFFICAS II proposes to test the hypothesis that treatment efficacy correlates to contact force parameters applied for pulmonary vein isolation (PVI) during AF ablation.
Prospective, randomized, controlled, multicenter, international clinical trial. The study population consist of patients with paroxysmal or persistent atrial fibrillation with out range hypertension or signs of sympathetic overdrive. Patient will be randomized into one of the following two groups. group 1 : patients will undergo pulmonary vein isolation, group 2: Patients will undergo pulmonary vein isolation and renal artery denervation.
This is a PI-initiated study that aims to evaluate the efficacy of two different methods of paroxysmal atrial fibrillation (PAF) ablation. There are currently two strategies for PAF ablation that are routinely performed by electrophysiology clinicians: (1) circumferential pulmonary vein ablation (CPVA) and (2) segmental pulmonary vein isolation (SPVI). However, it is not known if one approach is better than the other. This randomized study will evaluate and compare the efficacy of CPVA versus SPVI in subjects undergoing ablation for paroxysmal atrial fibrillation only. Subjects will have a 50/50 chance of receiving either the CPVA or SPVI ablation method.
A prospective, multicenter, interventional study to collect confirmatory evidence on the safety and effectiveness of the TactiCath® percutaneous ablation catheter for the treatment of symptomatic paroxysmal atrial fibrillation using contact force assisted irrigated radiofrequency ablation.
It has been demonstrated that successful cavotricuspid isthmus ablation may be effective in preventing paroxysmal atrial fibrillation. However, the effectiveness of only isthmus ablation on atrial fibrillation itself is unclear.
