Many patients with successful atrial flutter (AFL) ablation will develop atrial fibrillation (AF) during follow-up. This study aimed to determine whether prolonged inter-atrial conduction time (IACT) ...
Functional mitral regurgitation (FMR) is not uncommon in atrial fibrillation (AF) patients. We sought to investigate the association between FMR and atrial substrate remodeling as well as the ablation...
Whether patients with asymptomatic atrial fibrillation (AF) could benefit from radiofrequency catheter ablation (RFCA) remains unclear. This study aimed to compare the outcomes of RFCA between asympto...
Radiofrequency (RF) and cryoballoon (CB) catheter ablation are effective for pulmonary vein isolation (PVI) in atrial fibrillation (AF). This report presents an updated meta-analysis comparing the eff...
As a new complication, new-onset ventricular arrhythmias (VAs) post atrial fibrillation (AF) ablation have not been well defined. This prospective study aimed to describe the details of new-onset VAs ...
The aim of this prospective randomized clinical trial was to evaluate the early and late outcome following left atrial radiofrequency ablation during MV surgery for the treatment of contin...
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...
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...
The objective of the study is to evaluate the efficacy of the epicardial or endocardial radiofrequency ablation in the treatment of atrial fibrillation. It is a multicentric, prospective,...
The purpose of this study is to determine the long-term efficacy of radiofrequency catheter ablation in patients with chronic atrial fibrillation.
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).
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)
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
A condition characterized by a combination of OSTIUM SECUNDUM ATRIAL SEPTAL DEFECT and an acquired MITRAL VALVE STENOSIS.
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
