Cardiac Ablation Clinical Trials

Summary: The main purpose of this study is to investigate the workflow of the clinical use of the pulsed field (PF) ablation system (VARIPULSE catheter and TRUPULSE generator) when used for cardiac ablation with the new VARIPULSE Pro software in participants with paroxysmal atrial fibrillation (PAF; irregular heartbeat where episodes start and stop on their own, usually within seven days, often resolving w...

Summary: The objective of the study is to collect data on the usability and integration of the VERAFEYE Imaging and Guidance System in adult patients indicated to undergo a standard of care catheter-based ablation procedure for the treatment of Atrial Flutter (AFL), paroxysmal AF (PAF) or persistent AF (perAF). Results from this study may be used to guide development and refinement the VERAFEYE Imaging and...

Summary: The objective of the study is to collect data on the use of the VERAFEYE Anatomical Guidance System in adult patients indicated to undergo a catheter ablation procedure for the treatment of Atrial Flutter (AFL), paroxysmal AF (PAF) or persistent AF (perAF). The study will collect specific information on management of AFL/AF ablation procedures with the commercial VERAFEYE Anatomical Guidance Syste...

Summary: This study explores the relationship between myocardial fibrosis and patient outcomes in Atrial Fibrillation (AF), specifically after catheter ablation. It aims to use Cardiac CT, an accessible tool, to measure left ventricular extracellular volume (ECV) as an indicator of fibrosis. The study will assess if higher ECV levels correlate with increased risks of AF recurrence, hospitalization, and poo...

Summary: Conquer-AF is a prospective, multi-center, interventional, non-randomized clinical study that will enroll up to 400 subjects at up to 30 sites across the United States, Europe, and Australia. Subjects diagnosed with symptomatic recurrent paroxysmal or persistent atrial fibrillation after a single prior ablation procedure will be enrolled in this study. Each subject will undergo a study index redo ...

Summary: Ventricular tachycardia (VT) is a life-threatening heart rhythm disorder. Special pacemakers called implantable cardiac defibrillators (ICDs) help treat VT episodes, however they do not prevent the VT episodes from occurring. Catheter ablation for VT is a minimally-invasive and established procedure for preventing VT recurrence. This involves placing wires in the heart to find the diseased areas t...

Summary: This randomised study will compare pulsed field ablation and cryoballoon ablation with respect to ablation lesion quality as assessed by late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) at 3 months post-ablation. Patients scheduled for first-time AF ablation will be randomised in a 2:1 fashion to receive PVI-only, either by pulsed field ablation (Farapulse Pulsed Field Ablation S...

Summary: Atrial fibrillation ablation is the most common intervention performed worldwide. Up to 20 to 45% of patients show recurrence of AF within 12 month after catheter ablation, however its determinant are incompletely understood. The aim of the PROSPECT-AF study is to assess the predictors of AF recurrence within the 3 years following ablation using clinical variables and innovative biomarkers in a pr...

Objective: This study aims to compare the safety and effectiveness of the AccuSafe guidewire with the traditional transseptal needle in performing X-ray-free transseptal puncture under ICE guidance. Through this study, we hope to provide a safer and more effective method for transseptal puncture, reduce X-ray exposure for both patients and physicians, improve surgical success rates, and decrease the incidenc...

Summary: The goal of this clinical trial is to investigate the efficacy and safety of Qidong Yixin Granules in preventing recurrence in patients after radiofrequency catheter ablation for atrial fibrillation. The main question it aims to answer is: Can Qidong Yixin Granules reduce the recurrence rate of atrial fibrillation within 1 year in patients undergoing radiofrequency catheter ablation for atrial fib...

Summary: Comparative effectiveness randomized clinical trial, comparing endocardial radiofrequency ablation alone vs radiofrequency ablation combined with venous ethanol in patients with ischemic ventricular tachycardia -Venous Ethanol for Left Ventricular Ischemic Ventricular Tachycardia -VELVET clinical trial

Summary: The aim of this study is to define the importance of non-invasive programmed stimulation (NIPS) in risk stratification of ventricular tachycardia (VT) recurrence after catheter ablation and to determine the optimal treatment strategy. The primary objective is to establish whether a new VT ablation based on NIPS inducibility will reduce the risk of VT recurrence compared to antiarrhythmic drug ther...
