Filter by:This clinical investigation is intended to demonstrate safety and effectiveness of the Volt™ Pulsed Field Ablation (PFA) Catheter Sensor Enabled™, the Volt™ PFA Generator, Agilis™ NxT Steerable Introducer Dual-Reach™, and EnSite™ X EP System EnSite™ Pulsed Field Ablation Module (for simplicity of reference this device collection will hereafter be referred to as the Volt™ PFA system) for the treatment of symptomatic, recurrent, drug-refractory paroxysmal and persistent atrial fibrillation.
The goal of this Observational Prospective Multi-center Study is to observe the acute and long-term safety and performance outcomes after spatiotemporal dispersion-based AF/AT ablation utilizing the Volta Medical AI software in "real-life" clinical practice, without any imposed clinical workflow. Moreover, this study will allow to collect medico-economic data related to the tailored ablation strategy guided by the Volta Medical AI software.
Demonstrate the safety and effectiveness of the Ablacath™ Mapping Catheter and Ablamap® System in patients with all types of atrial fibrillation (AF) including paroxysmal or persistent or long-standing persistent, undergoing and De Novo or Redo procedures. Phenotype patients and demonstrate the prognostication power of Electrographic Flow (EGF®) maps among all subjects using 12-month follow-up outcomes following EGF-guided mapping and ablation.
A prospective cohort study to evaluate the association between various triggers encountered in daily life and induction of atrial arrhythmias (atrial fibrillation, atrial flutter, atrial tachycardia and premature atrial contractions) with the use of long-term monitoring devices. The collected data of personalized triggers and risk factors will be used to define the individual phenotype of atrial arrhythmia.
The LINQ QT Study is a prospective, non-randomized, multi-center, observational, post-market clinical study investigating QT interval changes due to antiarrhythmic drug loading.
This post-approval study is designed to provide continued real-world clinical evidence to confirm the safety and long-term effectiveness of atrial fibrillation (AF) radiofrequency (RF) technologies (e.g. TactiCath™ Contact Force Ablation Catheter, Sensor Enabled™ (TactiCath SE)) for the treatment of AF.
A randomised controlled trial to assess the efficacy of staged hybrid ablation when compared with standard catheter ablation in patients with non-paroxysmal atrial fibrillation (AF)
An observational, prospective, cohort study aiming to assess the potential predictive role of cardiopulmonary exercise testing in the prognosis of paroxysmal atrial fibrillation, in combination with echocardiographic indices and plasma biomarker values.
Precise identification of the atrial fibrosis is essential for successful catheter ablation of atrial arrhythmias in patients with atrial fibrillation. Voltage mapping of endocardial electrograms is currently used to delineate the anatomical substrate, but this is influenced by the direction of the activation wave front and is limited by the patient-specific thresholds. Mapping of local myocardial electrical impedance may overcome these limitations.
The study aims to evaluate and compare the incidence of atrial arrhythmias (including Post-Operative Atrial Fibrillation (POAF), atrial flutter, and atrial tachycardia) stratified by baseline Utah fibrosis stages and overall fibrosis (%) of the left atrial wall area. The investigators hypothesize that patients with a higher baseline Utah fibrosis staging will experience a higher incidence of POAF. The study also aims to evaluate and compare the in-hospital mortality, length-of-stay (LOS), complication rates (strokes, pneumonia, respiratory failure etc.) of the different Utah fibrosis stage cohorts. Perform cost analysis and compare between patients with POAF and patients without POAF. The investigators hypothesize that patients experiencing POAF will have a higher mortality rate, longer LOS, greater complications, and therefore, additional hospital costs.
