Active clinical trials for "Arrhythmias, Cardiac"

The new BIOTRONIK implantable cardioverter defibrillator (ICD) family Lumax 540 is capable of measuring the intrathoracic impedance on a daily basis and transmission of impedance trend data via the Home Monitoring technology. In future, this will allow for automatic early detection of imminent decompensation at a presymptomatic stage and immediate initialization of clinical meaningful therapeutic interventions preventing heart failure (HF) related hospitalizations. The aim of this investigation is to record long-term impedance trends in heart failure patients with and without heart failure related events (hospitalizations due to acute decompensation) in order to develop algorithms for device-based early detection and warning of HF deterioration accompanied by pulmonary congestion.

Sedation for catheter ablation of atrial fibrillation should be performed to achieve analgesia, immobilization, and maintenance of airway. Various anesthetic agents such as propofol, dexmedetomidine, and midazolam were investigated to achieve this goal. However, propofol and midazolam causes respiratory depression and dexmedetomidine occasionally accompanies hypotension or hypertension and bradycardia. Therefore, anesthetic agent that does not induce respiratory depression with stable hemodynamics is needed. Propacetamol (Denogan®, Yungjin, Seoul, Korea) is injectable prodrug of acetaminophen and 1st line drug for fever and pain. In a previous study, paracetamol reduced morphine consumption after surgery. And paracetamol does not cause respiratory depression. Thus, the investigators hypothesized that addition of propacetamol to previously used sedatives midazolam-remifentanil will reduce opioid consumption during the catheter ablation. Therefore, the investigators designed this study to investigate the role of addition of propacetamol to previous used midazolam-remifentanil sedation. This study will compare the opioid consumption and respiratory effect of propacetamol with placebo-control for catheter ablation of atrial fibrillation.

Allura Clarity is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes and shorter pulses are used, which are known to positively influence image quality . The primary aim of this study is to verify if a significant reduction in total procedural X-ray dose during electrophysiological interventions can be achieved by using advanced image processing (Allura Clarity).

The goal of this registry/observational study is to collect data on the clinical utility of MediGuide™ system in cardiac resynchronization therapy (CRT) implantation and electrophysiology (EP) procedures.

Introduction: Recent studies have suggested that other medications may be superior to amiodarone in controlling ventricular arrhythmias. However, a prospective and randomized comparison with lidocaine has not yet been described. Objective: This study aims to evaluate the effectiveness and safety of the use of amiodarone versus lidocaine in patients with stable ventricular tachycardias. Methodology: For this, a unicentric, randomized and prospective study will be carried out, in which the two drugs will be administered in a comparative manner. Hospital data (test results, medical outcomes, arrhythmia reversal, complications) of patients will be analyzed for safety and effectiveness. Expected results: The use of lidocaine is not inferior to amiodarone in the tolerability and reversion of stable ventricular tachycardias.

This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopy approach using Ensite NavX as the only imaging modality with conventional fluoroscopic approach for the catheter ablation of idiopathic ventricular arrhythmias; conventional fluoroscopic approach use fluoroscopy plus Ensite NavX or plus Carto as the imaging modality.

Catheter ablation of atrial fibrillation with electrical isolation of the pulmonary veins in the left atrium carries risk of esophagus thermal lesion. EnsoETM is a device . This study evaluates the benefit of using the EnsoETM, a device device for esophageal temperature adjustments, during catheter ablation of atrial fibrillation. Half of participants will undergo esophageal temperature adjustment during pulmonary vein catheter ablation, while the other half will undergo catheter ablation with no esophageal temperature adjustment.

Study to evaluate the safety and procedural performance of the KODEX - EPD System when used in the treatment of cardiac arrhythmias. An additional objective is to develop patient specific optimized therapy (PSOT PMCF) via machine learning to improve future treatment of cardiac arrhythmias (PSOT).

The aim of this prospective observational study is to evaluate the performance of Amigo RCS in ablation procedures for most common arrhythmias as compared to a conventional manual approach.

This is a research study to evaluate the electrical properties of heart tissue. The purpose of this study is to determine the impedance (electrical resistance) of different tissues on the outer surface of the heart. This may be important for distinguishing scarred heart muscle from fat that can be seen on the surface of the heart. This information may eventually be utilized in patients that undergo a procedure (called catheter ablation) for the treatment of life-threatening heart rhythms. Investigators expect a detectable difference between the impedance of normal and infarcted myocardium (approximately 50 ohms).
