POLARx Post Approval Study (POLARx PAS)
To collect clinical data on safety, effectiveness and procedural success of Boston Scientific's Cardiac Cryoablation System (includes all BSC commercially available POLARx/POLARx Fit catheters) when used to perform pulmonary vein isolation (PVI) in the ablation treatment of de novo Atrial Fibrillation (AF).
The Impact of Expandable Cryoballoon on Autonomic Control of the Heart
Approximately 40% of patients following cryoballoon ablation show signs of parasympathetic denervation. The presence of such effect is related to better outcomes in terms of clinical efficacy (freedom from atrial fibrillation). It could be hypothesized that larger sized balloon (POLARxFIT system) because of more antral position within the left atrium …
Pulmonary Vein Isolation Strategy of Very High Power Short Duration in Patients With Paroxysmal Atrial Fibrillation
This study aims to investigate the effect of reducing ablation time for a hybrid approach of vHPSD and AI-guided ablation using the QDOT Micro catheter in PVI among patients with PAF.
Biomarker-Guided Optimization of Transcutaneous Vagal Stimulation for Atrial (BiG tVNS-AF)
This proposal aims to determine the effects of tVNS on autonomic tone, atrial substrate and neuromodulators in patients with paroxysmal atrial fibrillation (AF), investigate the chronic effects of optimal tVNS on AF burden in patients with paroxysmal AF over a 6-month period, compared with sham stimulation, and identify physiological and …
BEAT AF - Braking Ectopic Atrial Trends In Atrial Fibrillation
Paroxysmal AF subjects with a documented ECG event of AF will be recruited to the study To assess the efficacy of CardiaCare™ RR2 wearable home-care neuromodulation system in reducing AF burden and symptoms in Paroxysmal AF patients
Evaluation of the Impact of Pulsed Field Ablation on Autonomic Nervous System Modulation in Paroxysmal Atrial Fibrillation
The objective of this clinical trial is to evaluate the impact of pulse field (PF) energy, both alone and in combination with radiofrequency (RF) energy, on vagal modulation during point-by-point pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (PAF). The effect of PF energy on ganglionated plexi (GP) …
FIH Study of PFLotus in Persistent Atrial Fibrillation
Single-shot pulsed-field ablation (PFA) catheters maximize pulmonary vein isolation (PVI) efficiency but are limited for focal or linear ablation. The goal of this clinical trial is to evaluate the safety and effectiveness of a novel, PFA catheter that transitions between large 'petals' (single-shot), and a small, spherical 'bud' (large-focal/linear), enabling …
A Study Assessing Arrhythmia Mapping With a Multi-Electrode Mapping Catheter
The purpose of this study is to assess the safety and feasibility of the investigational catheter for mapping the atrial and ventricular regions of the heart.
Waveform Periodicity Analysis in Patients With Persistent Atrial Fibrillation
STUDY DESIGN A prospective study. OBJECTIVE A single center clinical trial on the analysis of intracardiac atrial electrogram waveform periodicity for catheter ablation of persistent atrial fibrillation with OCTARAY™ Mapping Catheter, as prospective randomized controlled study. HYPOTHESIS The critical atrial substrates in maintaining persistent atrial fibrillation could be identified by …
Shock Energy for Electrical Cardioversion of Persistent Atrial Fibrillation
The goal of this clinical trial is to compare the efficacy of a maximum output shock for cardioverting atrial fibrillation between two commonly used defibrillators in New Zealand . These machines have different maximum energy outputs, and to date no head-to-head comparison cardioverting atrial fibrillation between the two has been …
