Comparison of PVI Plus Catheter Ablation or PVI Alone for the Treatment of AFib for Patients With Paroxysmal Atrial Fibrillation

There is a need to compare the efficacy of PVI versus PVI plus catheter ablation, which includes ablation of complex fractionated atrial electrograms (CFAE) and linear lesions in the same ...

Catheter Ablation Versus Thoracoscopic Ablation to Patients With Permanent Atrial Fibrillation

Patents with atrial fibrillation can be treated with the purpose of curing the arrhythmia.This may be achieved by catheter ablation and Maze surgery where the latter includes open heart su...

Relationship Between Fibroblast Growth Factor 23 and Recurrence of Atrial Fibrillation After Catheter Ablation

Effect of Left Atrial Enlargement on Success Rates of Catheter Ablation of Atrial Fibrillation in Women.

Catheter ablation (CA) is a well-established therapeutic option for patients with recurrent symptomatic atrial fibrillation (AF). Data on gender-related differences are limited with regard to baseline...

Predictors of 30-day readmissions after catheter ablation for atrial fibrillation in the USA.

Catheter ablation is considered as the mainstay treatment for patients with symptomatic atrial fibrillation (AF). We aimed to determine the predictors of 30-day readmission after catheter ablation for...

A Genetic Risk Score for Atrial Fibrillation Predicts the Response to Catheter Ablation.

The association of susceptibility loci for atrial fibrillation (AF) with AF recurrence after ablation has been reported, although with controversial results. In this prospective cohort analysis, we ai...

Procedural Outcomes of Patients With Heart Failure Undergoing Catheter Ablation of Atrial Fibrillation.

Catheter ablation is being increasingly performed for rhythm control of atrial fibrillation (AF). Heart failure (HF) frequently coexists with AF because they share common risk factors.

Effect of Catheter Ablation vs Antiarrhythmic Drug Therapy on Mortality, Stroke, Bleeding, and Cardiac Arrest Among Patients With Atrial Fibrillation: The CABANA Randomized Clinical Trial.

Catheter ablation is effective in restoring sinus rhythm in atrial fibrillation (AF), but its effects on long-term mortality and stroke risk are uncertain.

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)

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).

Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
