The shape of the heart cavities and the angle at which the pulmonary veins reach them are not always the same; rather, they vary according to the anatomical characteristics of each subject. Recently, ...

Veins in the lungs, or pulmonary veins, play a critical role not only in lung functioning but also in maintaining sufficient oxygen in tissues throughout the body. When a person sustains a pulmonary ...

In patients with paroxysmal AF originating from the PVs, extensive monitoring will frequently document coexisting paroxysms of both AT and AF. Similarly at electrophysiological evaluation, many ...

Over the past 5 years, catheter ablation of atrial fibrillation (AF) has evolved from an experimental procedure to one that is performed in most large medical centers throughout the world. The rapid ...

Deep vein thrombosis (DVT) is a condition where blood clots develop usually in the deep veins of the legs. Pulmonary embolism (PE) occurs when these clots break away and block the pulmonary artery.

BARCELONA, Spain—A comprehensive ablation strategy—a three-step approach that systematically targets the anatomical atrial structures known to be proarrhythmogenic—is superior to pulmonary vein ...

Catheter ablation is less successful for persistent atrial fibrillation than for paroxysmal atrial fibrillation. Guidelines suggest that adjuvant substrate modification in addition to pulmonary-vein ...

Although varicose veins and deep vein thrombosis (DVT) both affect the veins, these two conditions have different causes, involve different kinds of veins, and have unique symptoms. One is also more ...

Recent years have seen an enormous amount of experimental and clinical research into role of the pulmonary veins (PVs) in atrial fibrillation (AF). Advanced imaging techniques have confirmed the ...
