Atrial FibrillationAtrial Flutter

No randomized head-to-head comparison between the individual Non-vitamin K Antagonist Oral Anticoagulants (NOAC) exists. The DANNOAC-AF study is a nationwide cluster randomized cross-over study comparing efficacy and safety of the four NOACs, edoxaban, apixaban, rivaroxaban and dabigatran for oral anticoagulation in atrial fibrillation and atrial flutter across Danish hospitals and cardiology clinics.

Effect of Oral and Intravenous Diltiazem Protocol for Emergency Department Atrial Fibrillation

Atrial FibrillationAtrial Flutter

The primary objective of the study is to reduce hospital admission and decrease time to disposition through establishing an effective treatment protocol for AF and Atrial Flutter in the Emergency Department of Spectrum Health Lakeland. Secondary outcome is to measure if oral diltiazem is an effective HR controlling agent in AF RVR and Flutter.

Suture Closure AFtEr VEIN Access for Cardiac Procedures (SAFE-VEIN) Trial

Atrial FibrillationAtrial Flutter6 more

Primary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.

Cryoballoon Ablation as First Line Treatment of Atrial Flutter

Atrial Flutter Typical

Current guidelines recommend radiofrequency catheter ablation of the cavotricuspid isthmus as treatment for symptomatic/drug-refractory atrial flutter, in spite of the fact that recurrences of flutter and incidence of post-ablation atrial fibrillation are common. In this study, the investigators assess the hypothesis that the use of cryoballoon Pulmonary Vein Isolation ('novel' treatment) to achieve the electrical disconnection between the pulmonary veins and the heart will lead to higher rates of freedom from abnormal heart rhythms (atrial flutter, atrial fibrillation, or atrial tachycardia) and more improved quality of life than treatment using heat energy (radiofrequency ablation) directed at the cavotricuspid isthmus ('conventional treatment').

Prospective Observational Cohort Study of Fetal Atrial Flutter & Supraventricular Tachycardia

Atrial FlutterTachycardia11 more

The FAST Trial Registry is a prospective observational cohort study of fetuses with a new diagnosis of atrial flutter (AF) or supraventricular tachycardia (SVT) that is severe enough to consider prenatal treatment (see eligibility criteria below). Aims of the Registry include to establish a large clinical database to determine and compare the efficacy and safety of different prenatal treatment strategies including observation without immediate treatment, transplacental antiarrhythmic fetal treatment and direct fetal treatment from the time of tachycardia diagnosis to death, neonatal hospital discharge or to a maximum of 30 days after birth.

Fluoroscopic, Contact Force and Local Impedance With Ultra-high Density Mapping Guided Radiofrequency...

Typical Atrial Flutter

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: 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. 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. 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.

Clinical Cohort Study - TRUST

ArrhythmiasCardiac11 more

The "Long-term Outcome and Predictors for Recurrence after Medical and Interventional Treatment of Arrhythmias at the University Heart Center Hamburg" (TRUST) study is an investor-initiated, single-center, prospective clinical cohort study including patients treated with cardiac arrhythmias or at high risk for cardiac arrhythmias. The design enables prospective, low-threshold, near complete inclusion of patients with arrhythmias treated at the UHZ. Collection of routine follow-up data, detailed procedural information and systematic biobanking will enable precise and robust phenotyping.
