Background: Social status is an important predictor of poor health. Most studies of this issue
have focused on the lower echelons of society. Objective: To determine whether the …

Background— It is common practice to empirically limit the radiofrequency (RF) power when
ablating the posterior left atrium during atrial fibrillation ablation to avoid thermal injury to …

Background The initial experience with left atrial esophageal fistula (LAEF) secondary to atrial
fibrillation (AF) ablation procedures revealed a near-universal mortality. A comprehensive …

Second‐Generation Cryoballoon versus RF Introduction There are limited comparative data
on catheter ablation of atrial fibrillation (CAAF) using the second‐generation cryoballoon (…

Background Surgical exclusion of the left atrial appendage (LAA) can frequently yield incomplete
closure. Objective We evaluated the ischemic stroke/systemic embolization (SSE) risk …

Background While prior work has suggested that a high-grade atrioventricular block (HAVB)
in the setting of an acute coronary syndrome (ACS) is associated with in-hospital death, …

background Limited data exist on procedural and biophysical indicators of pulmonary vein (PV)
isolation durability after the cryoballoon ablation of atrial fibrillation (AF). Objective The …

Background— Percutaneous left atrial appendage (LAA) occlusion and novel pharmacological
therapies are now available to manage stroke risk in patients with nonvalvular atrial …

Background— Studies assessing the presence of a residual iatrogenic atrial septal defect (iASD)
after transseptal catheterization with 8F transseptal sheaths have suggested that the …

Background— Catheter ablation of left-sided atrial arrhythmias generally is performed using
a transfemoral venous approach through the inferior vena cava (IVC). In this report, we …
