Epicardial adipose tissue volume assessed by cardiac CT as a predictor of atria...
Teixeira, Bárbara Lacerda; Cunha, Pedro Silva; Jacinto, Ana Sofia; Portugal, Guilherme; Laranjo, Sérgio; Valente, Bruno; Lousinha, AnaIntroduction: In patients with atrial fibrillation (AF), up to one third have recurrence after a first catheter ablation (CA). Epicardial adipose tissue (EAT) has been considered to be closely related to AF, with a potential role in its recurrence. We aimed to evaluate the association between the volume of EAT measured by cardiac computed tomography (CT) and AF recurrence after CA. Methods: Consecutive AF patie...
A simplified single transseptal puncture approach using high-density 3D voltage...
Silva Cunha, Pedro; Teixeira, Bárbara Lacerda; Laranjo, Sérgio; Portugal, Guilherme; Valente, Bruno; Delgado, Ana Sofia; Pereira, MarianaBackground: An ablation catheter and a circular mapping catheter requiring a double transeptal puncture (TSP) for left atrial access have been conventionally used for atrial fibrillation (AF) ablation. Recently, different operators have combined a single transseptal puncture technique with 3D high-density mapping catheters for pulmonary vein isolation (PVI). Objective: This study aims to compare two strategies,...
The atrial fibrillation burden during the blanking period is predictive of time...
Silva Cunha, Pedro; Portugal, Guilherme; Laranjo, Sérgio; Alves, Marta; Luísa Papoila, Ana; Valente, Bruno; Sofia Delgado, Ana; Lousinha, AnaObjective: This study aimed to assess whether atrial fibrillation (AF) occurrence or its corresponding daily mean burden (in minutes/day) during the mid to late blanking period after pulmonary vein isolation (PVI), predicts AF recurrence. Methods: Analysis of consecutive first PVI ablation patients undergoing prolonged electrocardiogram (ECG) monitoring during the second and third months after PVI. The clinical...
