Prevention of Atrial Tachycardia After a Right Atriotomy II

Atrial Flutter

The investigators performed a prophylactic peroperative linear lesions connecting the tricuspid annulus with a right atriotomy and the atriotomy with the inferior caval vein to prevent atrial flutter on 15 consecutive adult patients undergoing surgery for congenital heart disease. Conduction time between electrodes placed on both sides of the lesions is measured on the second postoperative day. Coronary angiography and electrophysiology study using an electroanatomic mapping system to assess conduction across the line are performed three month after the operation.

APART: Prevention and Automatic Therapy of Atrial Arrhythmias in Patients With Paroxysmal Supraventricular...

Tachyarrhythmia

The goal of APART is the assessment of the therapeutic and preventive stimulation algorithms of the Medtronic AT500 and following devices in patients with atrial tachyarrhythmias and an indication for cardiac pacing according to the German guidelines. Medication is controlled throughout the study with a beta-blocker as the only antiarrhythmic drug.

Optimal Anti-tachycardia Therapy in Implantable Cardioverter-defibrillator (ICD) Patients Without...

Tachycardia

This study evaluates the impact of a new pacing mode avoiding unnecessary ventricular stimulation in combination with advanced dual chamber detection with slow VT management on the clinical outcome for hospitalization and mortality and inadequate therapy in medically stable, ICD-indicated patients with impaired left ventricular function (LVEF ≤ 40%) who do not have pacing indications and no indication for Cardiac Resynchronization Therapy (CRT). It compares a new pacing mode avoiding ventricular stimulation when not needed combined with dual chamber detection with a pure ventricular back up pacing and single chamber detection criteria with pure ventricular back up pacing. Therapies are compared in a prospective, randomized, single-blinded, parallel trial with a 24-month randomized treatment period. Randomization follows a 1:1 ratio. ICD therapy is enabled for all patients throughout the study. All patients receive optimal drug therapy for arrhythmia and heart failure treatment.

END - VT Cohort Study

Ventricular TachycardiaImplantable Defibrillator User1 more

Ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance which leads to sudden cardiac death (SCD), ventricular fibrillation, electrical storm, hemodynamic collapse, and syncope. VT patients with cardiomyopathy (diseased/scarred cardiac muscle) have the highest risk of SCD (<1-4%) and recurrent VTs (15-35%). Although an implantable cardiac defibrillator (ICD) is the most effective treatment option to prevent SCD, it does not eliminate it. Without VT prevention, recurrent VT and ICD shocks may increase the risk of heart failure and death. The primary objective is to determine the optimal treatment strategy to maximize event-free survival among cardiomyopathy patients with ventricular tachycardia (VT) by the creation of a prospective, multicenter, longitudinal cohort. Also, the investigators will evaluate the epidemiology of VT, adherence to guidelines, safety, effectiveness, and cost-effectiveness of current treatment options for secondary prevention of VT in the real-world Canadian VT population.

Ablation-Index Guided Ventricular Tachycardia Ablations

Ventricular TachycardiaVentricular Arrythmia1 more

Over the last decade, radiofrequency catheter ablation (RFCA) has become an established treatment for ventricular arrhythmias (VA). Due to the challenging nature of visualizing lesion formation in real time and ensuring an effective transmural lesion, different surrogate measures of lesion quality have been used. The Ablation Index (AI) is a variable incorporating power delivery in its formula and combining it with CF and time in a weighted equation which aims at allowing for a more precise estimation of lesion depth and quality when ablating VAs. AI guidance has previously been shown to improve outcomes in atrial and ventricular ablation in patients with premature ventricular complexes (PVC). However research on outcomes following AI-guidance for VT ablation specifically in patients with structural disease and prior myocardial infarction remains sparse. We aim at conducting a prospective observational multicenter registry investigating the efficacy and safety of AI-guided VA ablation in patient with ischemic and non-ischemic cardiomyopathy.
