Architecture of the pulmonary veins: relevance to radiofrequency ablation.
BACKGROUND Radiofrequency ablation of tissues in pulmonary veins can eliminate paroxysmal atrial fibrillation. OBJECTIVE To explore the characteristics of normal pulmonary veins so as to provide more information relevant to radiofrequency ablation. METHODS 20 structurally normal heart specimens were examined grossly. Histological sections were made from 65 pulmonary veins. RESULTS The lon...
متن کاملRandomized clinical trial of endovenous laser ablation compared with conventional surgery for great saphenous varicose veins.
BACKGROUND Endovenous laser ablation (EVLA) is a popular minimally invasive treatment for varicose veins. Surgical treatment, featuring junctional ligation and inversion stripping, has shown excellent clinical and cost effectiveness. The clinical effectiveness of both treatments was compared within a randomized trial. METHODS Some 280 patients were randomized equally into groups receiving eit...
متن کاملPredictors of Luminal Loss in Pulmonary Veins After Radiofrequency Ablation.
INTRODUCTION AND OBJECTIVES The reported incidences of stenosis after radiofrequency ablation of pulmonary veins are highly variable. Moreover, most studies have focused on severe stenosis and have overlooked mild stenosis. Our aims were to study postablation morphological changes in the pulmonary veins and to evaluate preablation magnetic resonance imaging predictors for stenosis. METHODS Ei...
متن کاملPulmonary veins: preferred site for catheter ablation of atrial fibrillation.
Atrial fibrillation (AF) is one of the most challenging arrhythmias to treat. Many patients have to accept this disorder and the medications required. Nonpharmacologic therapies have emerged as alternative methods of treatment. However, technical difficulty, low success rate, high recurrence, and complications still are obstacles. Pulmonary veins as the most common trigger foci of paroxysmal AF...
متن کاملLeft atrial ablation pendulum swinging back towards the pulmonary veins.
No cardiologist today is ignorant anymore of the fact that the pulmonary vein (PV) ostia and the surrounding left atrial (LA) tissue lie at the heart of atrial fibrillation (AF). The PVs may harbor rapidly firing foci that act as triggers for the initiation of paroxysms of AF. Moreover, the region certainly also plays a key role in its perpetuation towards persistent or even permanent forms by ...
