Clinical Usefulness of Virtual Ablation Guided Catheter Ablation of Atrial Fibrillation: Virtual Rotor Mapping and Catheter Ablation
Radiofrequency catheter ablation is effective in the treatment of patients with paroxysmal atrial fibrillation. In order to reduce the recurrence rate after catheter ablation, the investigators propose to apply 'virtual' ablation on patient-specific atria by simulating 3D atrial computer model. The investigators will conduct virtual rotor mapping in the patient …
Smartwatch and External Holter Monitoring to Detect Atrial Fibrillation in Patients With Cryptogenic Stroke
Stroke recurrence largely depends on the detection of the cause and the control of vascular risk factors, with occult atrial fibrillation (AF) being one of the most important. Prolonged ambulatory cardiac monitoring is recommended for detecting occult AF. Currently, there are non-invasive monitoring devices such as the textile Holter that …
Computed Tomogram Myocardial Thickness Map Guided pulmOnary Vein iSolaTion vs. Empirical Pulmonary Vein Isolation in Cryoballoon Ablation for Paroxysmal Atrial Fibrillation (UTMOST AF II)
New parameters or methods, such as ablation index, have been developed for the quantification of high-frequency energy used in pulmonary vein isolation, but there is no known method for atrial fibrillation considering individual differences in atrial tissue. The atrium is only 1/3 of the thickness of the ventricle and is …
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
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 …
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 …
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).
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.
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) …
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.
