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

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 …

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

Background In the US Food and Drug Administration (FDA) clinical trials of left atrial
appendage (LAA) closure, a postimplantation peridevice leak (PDL) of ≤5 mm (PDL≤5) was …

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

Purpose Catheter ablation of atrial fibrillation (CAAF) using the cryoballoon has emerged as
an alternate strategy to point-by-point radiofrequency. However, there is little comparative …

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, …

Recent studies have suggested that early repolarization (ER) might be associated with up to
1/3 of idiopathic ventricular tachycardia/ventricular fibrillation (VT/VF) cases (“malignant” ER)…
