CFAEs Guided Ablation Versus PVI in Persistent AF

Objective: The purpose of this study is to compare the efficacy and safety of complex fractionated atrial electrocardiograms (CFAEs) guided ablation to pulmonary vein isolation based ablat...

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, we propose t...

Utilizing a Novel Method to Map Sources of Atrial Fibrillation

This is an electrogram mapping study that tests the ability of a new signal processing technique called electrogram morphology recurrence mapping to locate drivers in participants with atr...

FAST Mapping During Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide with a prevalence of 8% in the elderly. AF is responsible for frequent hospitalizations, stroke, heart failure and ...

Mapping Electrogram Morphology Recurrence for Atrial Fibrillation Ablation

The overall goal of this project is to test the feasibility of performing real-time electrogram morphology recurrence (EMR) mapping in patients with persistent atrial fibrillation (AF) to ...

Ablation of atrial fibrillation: Facts for the referring physician.

Radiofrequency ablation has become a safe and effective treatment for atrial fibrillation. We believe that referral to an electrophysiologist for consideration of ablation may allow for better rhythm ...

Biomarkers determining prognosis of atrial fibrillation ablation.

Catheter ablation for rhythm control is recommended in specific patient populations with paroxysmal, persistent, or long-standing persistent atrial fibrillation. Pulmonary vein isolation is the corner...

Additional cavotricuspid isthmus ablation may reduce recurrent atrial tachyarrhythmia after total thoracoscopic ablation for persistent atrial fibrillation.

Unlike catheter ablation, little is known about the benefits of cavotricuspid isthmus (CTI) ablation in total thoracoscopic ablation (TTA) of atrial fibrillation (AF). This study aimed to investigate ...

Disease progression after ablation for atrial flutter compared with atrial fibrillation: A nationwide cohort study.

The aim of this study was to study the risk of death and development of arrhythmia and/or subsequently heart failure after an atrial flutter ablation procedure compared with an atrial fibrillation (AF...

Approaches to Catheter Ablation of Nonparoxysmal Atrial Fibrillation.

We describe the technical aspects and outcomes of several different ablation strategies for nonparoxysmal (persistent and long-standing persistent) atrial fibrillation (AF) and discuss our ablation st...

Medical and Biotech [MESH] Definitions

Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).

Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.

A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)

Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.

A THROMBIN inhibitor which acts by binding and blocking thrombogenic activity and the prevention of thrombus formation. It is used to reduce the risk of stroke and systemic EMBOLISM in patients with nonvalvular atrial fibrillation.
