Catheter Ablation as Treatment for Atrial Fibrillation - 1/1/17
ثبت نشده
چکیده
Radiofrequency ablation (RFA) using a percutaneous catheter is a common approach to treat supraventricular arrhythmias. Atrial fibrillation (AF) frequently arises from an abnormal focus at or near the junction of the pulmonary veins and the left atrium, thus leading to the feasibility of more focused ablation techniques directed at these structures. Catheter-based ablation, using RFA or cryoablation, is being studied in the treatment of various types of AF.

Atrial fibrillation (AF) is associated with inflammatory and hypercoagulability state. Previous studies evaluated the safety and efficacy of dabigatran and warfarin in prevention of thrombothic complications. This study was intended to assess the influence of these drugs on hemostatic and inflammatory markers among patient underwent pulmonary vein ablation. A total of 100 patients with AF w...

BACKGROUND Catheter ablation of pulmonary vein ectopic foci is a potentially curative treatment strategy for patients with atrial fibrillation. However, identification of arrhythmogenic pulmonary veins with conventional mapping is difficult, especially in patients with rare focal activity, multiple active foci, or extrapulmonary foci. The present study was designed to investigate use of simulta...
متن کاملPulmonary Vein Stenosis After Catheter Ablation of Atrial Fibrillation
Catheter ablation around the pulmonary veins (PVs) has become the treatment of choice for symptomatic patients with atrial fibrillation (AF) who do not respond to pharmacological therapy [1–6]. Over the past few years, a variety of strategies have been developed to achieve cure of AF [7–16]. PV stenosis is a known potential complication of radiofrequency ablation (RF) around the PVs [17–24] and...

The era of catheter ablation for the treatment of arrhythmias began in 1981, when Dr. Melvin Scheinman performed the first atrioventricular junction ablation using direct-current shocks in a patient with drug-refractory atrial fibrillation and an uncontrolled ventricular rate.1 Because of the barotrauma associated with intracardiac high-energy shocks, direct-current catheter ablation played onl...
