Cryoballon Versus Radiofrequency Ablation for Persistent Atrial Fibrillation

A randomized trial has recently demonstrated non-inferiority of cryoballoon vs. radiofrequency (RF) catheter ablation in patients with drug-refractory paroxysmal atrial fibrillation (AF). ...

Radiofrequency Ablation of Drivers of Atrial Fibrillation

The purpose of this study is to assess the value of ablation of high frequency sources following circumferential pulmonary veins isolation in patients with paroxysmal and persistent atrial...

Effects of Catheter Ablation on Burden of Atrial Fibrillation (MRICEMAN)

The study will assess the atrial fibrillation burden recorded By implantable loop recorder at 12 and 24 months compared to baseline. The patients with clinical indication fo catheter ablat...

Study of Statin for Reduction of Postoperative Paroxysmal Atrial Fibrillation

The study will select all recruited patients with paroxysmal atrial fibrillation will be randomly allocated to receive oral rosuvastatin 20mg/day or blank control from 7 days before ablati...

Radiofrequency Ablation (RFA) Versus Antiarrhythmic Drug Treatment in Paroxysmal Atrial Fibrillation

Atrial fibrillation is the most common heart arrhythmia afflicting approximately 1% of the Danish population. Medical antiarrhythmic treatment is only moderately effective and has the risk...

Percutaneous versus thoracoscopic ablation of symptomatic paroxysmal atrial fibrillation: a randomised controlled trial - the FAST II study.

The most efficient first-time invasive treatment, for achieving sinus rhythm, in symptomatic paroxysmal atrial fibrillation has not been established. We aimed to compare percutaneous catheter and vide...

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 ...

Pulmonary vein volume predicts the outcome of radiofrequency catheter ablation of paroxysmal atrial fibrillation.

Catheter ablation of atrial fibrillation (AF) is an effective therapy for selected groups of patients. We evaluated whether quantification of left atrium (LA) or pulmonary vein (PV) by using multi-det...

Assessment of left atrial remodeling in paroxysmal atrial fibrillation with speckle tracking echocardiography: a study with an electrophysiological mapping system.

This study aimed to evaluate left atrial (LA) remodeling and fibrosis in paroxysmal atrial fibrillation (AF) using speckle tracking echocardiography (STE) based on the findings with radiofrequency ca...

Cryoballoon vs. radiofrequency ablation for atrial fibrillation: a study of outcome and safety based on the ESC-EHRA atrial fibrillation ablation long-term registry and the Swedish catheter ablation registry.

Pulmonary vein isolation (PVI), the standard for atrial fibrillation (AF) ablation, is most commonly applied with radiofrequency (RF) energy, although cryoballoon technology (CRYO) has gained widespre...

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.

The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.
