Does Atrial Fibrillation (AF) Termination Without Additional Ablation Influence Outcome?

Atrial Fibrillation

This prospective study aims to investigate if termination of atrial fibrillation (AF) after pulmonary vein antrum isolation (PVAI) without additional ablation of non-PV triggers, in long-standing persistent (LSP) AF, is enough to ensure long-term success.

PREdicting Atrial Fibrillation or Flutter

Atrial FibrillationAtrial Flutter

The purpose of this study is to determine, through continuous monitoring with a cardiac monitoring device placed under the skin, the incidence of atrial fibrillation or flutter (AF). The cardiac monitor will be placed in patients without symptoms but at risk for AF. It is hoped that this information may assist health care professionals in treatment decisions related to the early identification of patients at high risk for AF.

The purpose of this study is to determine choice of anticoagulant therapy during acute and chronic stages of ischemic stroke/TIA and short- and long-term outcomes, including stroke recurrence and bleeding complications, in patients having nonvalvular atrial fibrillation.

Silent Atrial Fibrillation - Screening of High-risk Groups for Atrial Fibrillation (The Silence...

Atrial Fibrillation

The primary aim of the present study is to screen high-risk type 2 diabetes patients and heart failure patients without any history of atrial fibrillation (AF), ongoing oral anticoagulation (OAC) treatment, implanted device or recent stroke/Transient Ischemic Attack (TIA), for silent AF. Moreover, we aim to establish the prevalence of two or more risk factors for stroke in patients with heart failure and diabetes mellitus type 2 (DM2) with the aim of assessing the feasibility for this group to undergo AF screening. Overall, the aim of the study is to prevent stroke in high-risk patients groups through identification of silent (asymptomatic) atrial fibrillation.

Atrial Fibrillation Detection Using Garmin Wearable Technology

Atrial Fibrillation

The purpose of this study is to evaluate the feasibility of detecting atrial fibrillation (AF) in patients with AF using a wearable wrist device/smart watch.

Evaluation of Optimal Ablation Index for Pulmonary Vein Isolation in Patients With AF Prospective...

Atrial Fibrillation

In this study, the investigators identify the optimal AI value for achieving good acute outcomes in PVI. Through the Phase 1 study, the investigators will prospectively analyze data including ablation parameters, AI and acute outcomes of 20 patients performed PVI with conventional ablation strategy (AI-blinded). After Phase 1 study results, optimal target AI value for each predefined PV segment will be determined. Then, by applying optimal AI values derived from the Phase 1 study, the investigators will evaluate the feasibility of the AI-guided procedure and verify the optimal AI value for acute PVI outcomes in the prospectively enrolled patients (n = 30) in the Phase 2 study.

Left Atrial Function Analysis for Patients With Persistent Atrial Fibrillation Undergoing Pulmonary...

Persistent Atrial FibrillationCatheter Ablation

This prospective observational study is designed to describe the factors determining the success of pulmonary vein isolation (PVI) for patients with persistent atrial fibrillation (AF). These factors - described as left atrial (LA) function - are simultaneously studied by multi-modal techniques in patients undergoing radiofrequency ablation. The simultaneous measurements are conducted before the PVI in AF and after the sinus rhythm converted due to PVI. These measurements include invasive LA pressure monitoring, LA voltage map creation, LA strain evaluation by transthoracal echocardiography, LA scar-mapping by cardiac MRI, defining biomarkers from blood samples. During the one year follow-up period rhythm monitoring is conducted by regular Holter-monitoring. Our aim is to define the predictive values of the above mentioned factors and to create a new score system for predicting PVI success in persistent AF population.

Transient Electrocardiogram Assessment in Stroke Evaluation

Atrial FibrillationStroke

In stroke survivors, atrial fibrillation is typically detected with short-term electrocardiogram (ECG) monitoring in the stroke unit. Prolonged continuous ECG monitoring is impractical and requires substantial resources while insertable cardiac monitors are invasive and costly. Chest and thumb-ECG could provide an alternative for atrial fibrillation detection post-stroke. The primary objective of our study is to assess the incidence of newly diagnosed atrial fibrillation during 28 days of chest and thumb-ECG monitoring in patients with cryptogenic stroke. Secondary objectives are to assess Health-related Quality of Life using Short Form-36 and the feasibility of the Coala Heart Monitor in patients with stroke.
