Bleeding Complications in Patients Undergoing Pulmonary Vein Isolation without Discontinuance of Warfarin

Pulmonary vein isolation without left atrial mapping

BACKGROUND One of the crucial points during in most approaches developed for ablation of atrial fibrillation (AF) is the ability to identify the pulmonary vein (PVs) and to accurately locate their ostia. OBJECTIVES The purpose of this case series was to investigate a simplified method for fusion of the multislice computer tomography (CT) derived 3D dataset with the electroanatomical map in or...

How to Achieve Complete and Permanent Pulmonary Vein Isolation without Complications

The efficacy and safety of catheter ablation for the management of atrial fibrillation (AF) has been improved in recent years. Radiofrequency (RF) catheter ablation for maintaining sinus rhythm is superior to the current antiarrhythmic drug therapy in selected patients. Pulmonary vein isolation (PVI) is the cornerstone of various catheter ablation strategies. It is well recognized that pulmonar...

Complications of pulmonary vein angiography.

Aberrant Pulmonary Vein Draining to Left Atrial Roof in a Patient Undergoing Percutaneous Circumferential Pulmonary Vein Isolation

Implication for health policy/practice/research/medical education: In this image, we are trying to convey an important message regarding the detection of vascular anomaly in patients who are candidate for catheter LA ablation. Detection of the aberrant PVs is highly important because these PVs may be the origin of the ectopies initiating AF and it helps us to prevent important complications suc...

Spontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation.

A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.
