Cryotherapy Versus Radiofrequency Catheter Ablation Research Program

Atrial FibrillationAtrial Tachycardia2 more

A program of research has been set up at St. George's Hospital, London studyng the practicalities of catheter ablation. The current practice of catheter ablation is being studied for a range of arrhythmias including PAF, persistent AF, advanced persistent AF and resistant WPW.

PASO Automated Template Matching for PVC Ablation

PVC - Premature Ventricular ComplexCardiomyopathies2 more

Pacemapping is an essential tool during ablation of idiopathic PVC and VT. Automated template matching has been shown to have a significant influence on PVC ablation procedures, but the PASO module of CARTO3 has not been studied in a randomized trial. The Aim of this study is to evaluate the additional benefit of PASO template matching on PVC ablation procedure with regard to procedural parameters and outcome when compared with conventional pace mapping. A total of 144 pts will be randomised in a 1:1 fashion to PVC ablation guided by conventional pacemapping vs PVC ablation guided by PASO pacemapping. Patients will be follow up with Holter-ECG and TTE after 3 and 12 months.

Optimal Pharmacological Therapy In Implantable Defibrillator Patients (OPTIC)

Ventricular Tachycardia

This is an open parallel design randomized trial of amiodarone plus a beta blocker vs a beta blocker alone vs sotalol for the prevention of ICD shocks in patients receiving an ICD for spontaneous or inducible ventricular tachycardia or fibrillation

Right Ventricular Defibrillation Lead Select Site Study

Heart FailureCongestive2 more

This study will compare single coil right ventricular defibrillation leads for implanted cardioverter/defibrillators (ICDs) in the apical and high septal locations. It is hypothesized that RV septal positions are at least as good as apical positions using formally measured defibrillation thresholds(DFTs), and that they may have long term advantages in reducing left ventricular dysfunction.

Contrast ICE for Myocardial Scar in VT Ablations

Ventricular TachycardiaIschemic Cardiomyopathy

There is a high correlation between scar areas identified by contrast-enhanced ICE and scar areas identified by conventional electroanatomic mapping. Therefore, the investigators will assess the utility of contrast-enhanced ICE to identify and localize myocardial scar real-time during VT ablation procedures.

DOACs for Stroke Prevention Post Ventricular Tachycardia Ablation

Ventricular TachycardiaPremature Ventricular Contraction1 more

The purpose of this study is to learn if taking a drug called direct oral anticoagulant after an ablation procedure keeps blood clots from forming and lowers the chance of having a stroke in patients with ventricular tachycardia or arrhythmia (VT).

Inducibility and Stability of Ventricular Tachycardia Inpatients Undergoing VT Ablation Under General...

Ventricular Tachycardia

This research study is being done to see whether general anesthesia (GA) affects our ability to start ventricular tachycardia (VT) during an VT ablation procedure. Data collected during this research study will help electrophysiologists and anesthesiologists to make the best decisions about the best anesthetic conditions to use to perform VT ablations. This research study is a "pilot" study. Pilot studies are done on a small group of subjects to learn if a larger study would be useful.

Supraventricular Tachycardia

The supra ventricular tachycardia is the most common symptomatic arrhythmia in pediatrics. Amiodarone is an antiarrhythmic drug used in this indication. Pharmacokinetic, efficacy and safety data are not known in the pediatric population due to the lack of a suitable specialty available on the market. The development of an amiodarone oral solution formulation adapted to this age group should provide a therapeutic alternative and collect data on the pharmacokinetics, efficacy, acceptability and tolerability of the drug.

Prospective Cardiac Ultrasound Imaging Study With Demonstrator

Ventricular Tachycardia

The Prospective Cardiac Ultrasound Imaging Study is a single center, single arm, feasibility study. The study aims at collecting cardiac ultrasound data from patients diagnosed with ventricular tachycardia, during rest and short breath hold sequences. This study is part of the engineering studies linked to the CardioKit-Minimum Viable Product project. The CardioKit prototype used in the study can monitor cyclical heart-beat motion, cyclical respiratory motion and non-cyclical heart position changes while the patient is lying in supine position.

Atropine in Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)

Catecholaminergic Polymorphic Ventricular Tachycardia

To test the hypothesis that increasing the sinus node rate with atropine treatment prior to exercise will reduce exercise-triggered ventricular ectopy compared to baseline in patients with CPVT.
