Pre-existent left atrial scarring in patients undergoing pulmonary vein antrum isolation: an independent predictor of procedural failure.
OBJECTIVES The goal of this study was to assess the impact of left atrial scarring (LAS) on the outcome of patients undergoing pulmonary vein antrum isolation (PVAI) for atrial fibrillation (AF). BACKGROUND Left atrial scarring may be responsible for both the perpetuation and genesis of AF. METHODS A total of 700 consecutive patients undergoing first-time PVAI were studied. Before ablation,...
متن کاملLeft atrial-pulmonary vein reentrant tachycardia following pulmonary vein isolation.
Pulmonary vein isolation has become the cornerstone of ablation for atrial fibrillation. However, it is sometimes followed by the development of left atrial macro-reentrant tachycardia. There is evidence to suggest that the myocardial sleeves within the pulmonary veins may be implicated in the mechanism of the tachycardia. Here we present a case of a post-ablation macro-reentrant tachycardia, i...
متن کاملPulmonary 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...
متن کاملSegmental pulmonary vein antrum isolation using the "large-size" lasso catheter in patients with atrial fibrillation.
BACKGROUND The limited efficacy and complications of segmental ostial pulmonary vein isolation (PVI) for treating atrial fibrillation (AF) have been discussed so, in the present study the feasibility and efficiency of performing segmental pulmonary vein (PV) antrum isolation to treat AF were assessed. METHODS AND RESULTS A total of 187 patients with drug-refractory AF (paroxysmal 120, persist...
متن کاملAtrial fibrillation with a giant left atrial appendage can be successfully treated with pulmonary vein antrum isolation
A congenital giant left atrial appendage (LAA) is a rare condition only described in case reports [1]. Supraventricular tachycardias, including atrial fibrillation (AF), and systemic embolisation are the most common clinical findings [1, 2]. Almost all reported cases are treated by resection of the giant LAA [1]. A few cases are treated conservatively [3, 4]. Catheter ablation has not been repo...
