Filter by:Catheter ablation is a first-line treatment for patients with cavotricuspid isthmus (CTI) dependent atrial flutter (AFL; also known as typical AFL), a common arrhythmia. This is done using radiofrequency (RF) catheters and single-procedure success is approximately 95%. Ablation is often done using one of three methods: 1. fluoroscopically, using X-rays to guide the operator to visualise catheter position within the heart. This method involves the most radiation exposure to patient and operator. Ablation is generally performed for a set time-period (eg. 30-60secs) to ensure each ablation lesion is successful. 2. using a 3-dimensional mapping system which allows the catheters to be magnetically located and visualised on a monitor without X-rays, and using "contact force" (CF) sensing catheters. This requires minimal X-ray use, and by ensuring a minimum degree of force between catheter tip and the heart before applying RF for a set time-period (eg. 30 seconds), operators can be more confident of successful lesions. 3. using an ultra-high density mapping system which uses magnetic tracking as above, but allows higher resolution visualisation of the cardiac electrical system with potential for improving procedure success; this has not yet been formally evaluated for AFL. Catheters using this method use "local impedance" (LI) instead of CF. This is a direct measure of heart tissue impedance with real-time changes during ablation. A minimum drop or plateau in the LI value during ablation allows confidence of lesion success, without the need to ablate for a pre-defined time-period. This could potentially reduce ablation time and subsequent complications, but has also not yet been formally compared to the above for this indication. This prospective randomised study aims to compare these three standard of care procedures to determine if differences in ablation metrics, efficacy and safety exist.
Anticoagulants are a leading cause of acute injury from adverse drug events, leading to ~20,000 serious injuries reported to the Food and Drug Administration per year and more than 220,000 emergency department visits annually. Therefore, we propose to implement a health information technology (HIT) population management tool at two distinct anticoagulation clinics that will allow the care team to assign and track tasks essential for timely patient monitoring. We will examine its effect on anticoagulation management outcomes through a randomized trial, hypothesizing that such interventions can be effective as well as cost-effective strategies to improve patient safety in the context of anticoagulation management services.
This study is an observational study without any hypothesis testing. It intended to observe the clinical application of electrophysiological mapping and catheter ablation of atrial tachycardia post atrial fibrillation ablation or cardiac surgery guided with Rhythmia System.
Demonstrate the safety, feasibility and usability of the EPD D700 system, for the first time in humans, in subjects undergoing ablation for the treatment of atrial flutter. Prospective, single-center, non-randomized, open label, single arm study. Ten consented subjects who are scheduled to undergo ablation due to atrial flutter. All subjects will undergo baseline assessment; intervention (standard fluoroscopy guided RF ablation procedure) and post procedure follow up. All subjects will have a follow up visit within 24 hours post procedure.
The purpose is to compare long term occurrence of atrial arrhythmias including atrial fibrillation (AF) and thromboembolic complications including cerebrovascular events (CVE) in patients with typical atrial flutter (AFLT) undergoing cavo-tricuspid isthmus (CTI) ablation alone versus CTI ablation combined with pulmonary vein isolation (PVI).
