Pivotal Clinical Study of the CardioFocus Endoscopic Ablation System - Adaptive Contact (EAS-AC) (HeartLight) in Patients With Paroxysmal Atrial Fibrillation (PAF)
The purpose of this study is to demonstrate the safety and effectiveness of the CardioFocus Endoscopic Ablation System with Adaptive Contact (HeartLight) in the treatment of atrial fibrillation by creating electrical isolation of the pulmonary veins.
A randomized, controlled trial designed to demonstrate the safety and effectiveness of the experimental device to deliver pulmonary vein isolation as a treatment for symptomatic atrial fibrillation.

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).
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)
A condition characterized by the recurrence of HEMOGLOBINURIA caused by intravascular HEMOLYSIS. In cases occurring upon cold exposure (paroxysmal cold hemoglobinuria), usually after infections, there is a circulating antibody which is also a cold hemolysin. In cases occurring during or after sleep (paroxysmal nocturnal hemoglobinuria), the clonal hematopoietic stem cells exhibit a global deficiency of cell membrane proteins.
An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.
Removal of tissue by vaporization, abrasion, or destruction. Methods used include heating tissue by hot liquids or microwave thermal heating, freezing (CRYOABLATION), chemical ablation, and photoablation with LASERS.
The investigators have recently shown that anatomic ganglionated plexi (GP) ablation is inferior to circumferential pulmonary vein (PV) ablation for the treatment of paroxysmal AF. In this...
This is a randomized controlled study of the Bard High Density Mesh Ablation System for treatment of paroxysmal atrial fibrillation. This study will determine if the HD Mesh Ablation Syst...
Atrial fibrillation (AF) is a chaotic heart rhythm of the top chambers of the heart. AF occurs in up to 10% of the population over the age of 60. It is associated with tiredness, impaired...
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 chronic atrial fi...
This is a demonstration of safety and efficacy of the ablation for pulmonary vein isolation in the treatment of paroxysmal atrial fibrillation.
Catheter ablation for paroxysmal atrial fibrillation is a meanwhile established therapy option, which is most frequently performed using radiofrequency ablation. Mid-term success rate of 70 % are ac...
There are limited data comparing radiofrequency catheter ablation with antiarrhythmic drug therapy as first-line treatment in patients with paroxysmal atrial fibrillation.
The gold standard in ablation of paroxysmal atrial fibrillation (PAF) is radiofrequency (RF) based point by point pulmonary vein isolation (PVI). In the majority of patients with PAF (80 %) PVI can...
Development of atrial fibrillation is one of the primary indicators of cor triatriatum in adults. Here we describe a case of a patient suffering cor triatriatum coexistent with frequent paroxysmal atr...
BACKGROUND: Atrial fibrillation (AF) recurrence after ablation is difficult to predict. The development of AF is associated with inflammation, and inflammatory markers such as big endothelin-1 (big ET...
