Left atrial diverticula in patients referred for radiofrequency ablation of atrial fibrillation: assessment of prevalence and morphologic characteristics by dual-source computed tomography.
BACKGROUND The anatomic features of left atrial diverticula (LAD) are still unclear in patients with atrial fibrillation (AF). The purpose of this study was to evaluate the prevalence and morphological characteristics of LAD in patients referred for radiofrequency transcatheter ablation of AF with dual-source computed tomography. METHODS AND RESULTS Dual-source computed tomography images were...

متن کاملAnatomical Characteristics of Pulmonary Veins for the Prediction of Postoperative Recurrence after Radiofrequency Catheter Ablation of Atrial Fibrillation
BACKGROUND The relationship between focal pulmonary vein potential and atrial fibrillation (AF) has been confirmed. Pulmonary vein (PV) isolation and circumferential pulmonary vein ablation have been the most commonly used procedures of radiofrequency ablation. However, few studies have investigated the relationship between anatomical characteristics of PV and AF recurrences after radiofrequenc...
متن کاملLeft Atrial, Left Atrial Appendage and Pulmonary Veins Anatomical Variants in Patients with Atrial Fibrillation versus Patients in Sinus Rhythm.
The aim of the study is to evaluate by multidetector computed tomography (MDCT) the prevalence, location and size of LA (left atrial) diverticula and accessory appendages, the prevalence of PVs anatomical variants and LAA (left atrial appendage) shapes in patients with atrial fibrillation (AF) compared to patients in sinus rhythm (SR). Images obtained by MDCT in a group of 100 patients with <1 ...
متن کاملEffects Of Fast Pathway Ablation On The Concealment Zone And Electrophysiological Behavior Of AV-Node During Atrial Fibrillation.
Objectives: Dual pathways have a determinant role in the occurrence of atrio nodal tachyarrhythmia (AVNRT). The aim of present study is to determine the role of slow pathway (SP) in the concealment zone and protective role of AV node during atrial fibrillation (AF). Material &Methods: In 7 isolated nodal rabbit preparation zone of concealment and concealed conduction is quantified by Specif...
