NCT ID: NCT05496088 Recruiting - Atrial Fibrillation Clinical Trials

Persistent AF Catheter Ablation: Re-PVI vs. Re-PVI + Continuous Complex Activity Mapping and Ablation - AF-CAM

Start date: June 3, 2021
Phase: N/A
Study type: Interventional

Major objective is to compare the efficacy of adding additional ablation step (targeting areas of complex, continuous electrical activity in LA) beyond Re-PVI during catheter ablation of Atrial Fibrillation (AF) in patients undergoing 2nd ablation procedure. Underlying hypothesis that in addition, to Re-PVI, an ablation step targeting areas of complex continuous activity will increase atrial arrhythmias freedom compared to Re-PVI only ablation.

NCT ID: NCT05494034 Not yet recruiting - Stroke Clinical Trials

Yield of Implantable Cardiac Monitoring Device in Patients With Acute Ischemic Stroke.

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

In this prospective cohort study, the investigators aim to investigate the incidence of ICM-detected AF in unselected ischemic stroke patients and its association with anticoagulation initiation and stroke recurrence.

NCT ID: NCT05493852 Not yet recruiting - Clinical trials for Paroxysmal Atrial Fibrillation

A RWS of the FARAPULSE in A Chinese Population With PAF

Start date: September 30, 2022
Study type: Observational

The real world study is a retrospective and/or prospective, single-center, single-arm observational study to observe the safety and effectiveness of the FARAPULSE Pulsed Field Ablation System for treatment of recurrent, symptomatic Paroxysmal Atrial Fibrillation (PAF) in a Chinese population.

NCT ID: NCT05492760 Not yet recruiting - Atrial Fibrillation Clinical Trials

Evaluation of Recurrence Risk of Atrial Fibrillation After Cryoballoon Ablation

Start date: August 1, 2022
Study type: Observational

The recurrence of atrial fibrillation(AF) after pulmonary vein ablation with cryoballoon is conducted by many factors . The previous studies found larger left atrial and longer AF duration are tied to higher risk of AF recurrence. The characters of ablation procedure is also of critical importance to durable clinical success such as temperature features and time-to-isolation (TTI). The aim of our study is to develop an tool of recurrence risk evaluation with both pre-procedure and procedure factors.

NCT ID: NCT05489445 Recruiting - Atrial Fibrillation Clinical Trials

All Inclusive Kodex - EPD Study

Start date: September 15, 2021
Study type: Observational

This is a post-market, prospective, observational study to evaluate the accuracy of KODEX 3D-imaging. The research study will collect pre-operative and post-operative cardiac imaging data from adult arrhythmia patients who are already undergoing catheter-based electrophysiological (EP) intervention (ablation procedures) using the FDA approved medical device KODEX - EPD™ system.

NCT ID: NCT05486364 Recruiting - Atrial Fibrillation Clinical Trials

DIGITAL fOllow uP for aTrial fIbrillation After pulMonary veIn iSolaTion (DIGITAL OPTIMIST)

Start date: December 20, 2021
Phase: N/A
Study type: Interventional

Recurrence of atrial fibrillation (AF) after a pulmonary vein isolation (PVI) procedure is frequent. Current follow up with Holter monitoring and electrocardiograms (ECG) during outpatient clinic consultations cover only short time stretches and require hospital visits. Mobile health solutions with rhythm monitoring using photoplethysmography (PPG) technology on a smartphone could extend rhythm monitoring time, while lowering hospital visits and cost. This study aims to compare the performance of a digital health solution using PPG technology on a smartphone versus the current standard of care to monitor for AF recurrence after a PVI procedure.

NCT ID: NCT05486221 Recruiting - Atrial Fibrillation Clinical Trials

Atrial Imaging and Cardiac Rhythm In Embolic Stroke

Start date: December 17, 2020
Study type: Observational

The ARIES study is an observational study in which patients with a recent acute ischemic stroke of cryptogenic aetiology are consecutively enrolled in order to perform a extensive cardiologic work-up. The main objective is to study parameters that could predict arrythmias on prolonged monitoring and also echocardiographic parameters of left atrial disfunction that could predict the presence of a hidden atrial fibrilation and recurrent ischemic events in patients with cryptogenic stroke.

NCT ID: NCT05481359 Not yet recruiting - Clinical trials for Cardiovascular Diseases

This Study is to Evaluate Ablamap Software in Patients Undergoing Ablation for Atrial Fibrillation.

Start date: August 2022
Study type: Observational [Patient Registry]

This post-market global registry will evaluate the ability of the Ablamap® Software to identify atrial fibrillation sources and guide ablation therapy in patients with atrial fibrillation.

NCT ID: NCT05477602 Not yet recruiting - Atrial Fibrillation Clinical Trials

The Automated Calculation of AF Cycle Length and Complexity Using a Novel EP Recording System

Start date: September 5, 2022
Study type: Observational

Collect electrophysiological data during atrial fibrillation (AF) ablation procedures to assess the performance of a Signal Complexity Visualization algorithm designed to be integrated into the CathVision ECGenius® System.

NCT ID: NCT05477147 Not yet recruiting - Atrial Fibrillation Clinical Trials

Re-Ablation Using a Tailored Approach Targeting EGM-Dispersion

Start date: November 1, 2022
Phase: N/A
Study type: Interventional

Multi-center, international, non-randomized clinical trial evaluating the use of Volta's VX1 algorithm as used in combination with repeat catheter ablation after AF recurrence after previous catheter ablation.
