Background: Fluoroscopy is commonly used during atrial fibrillation (AF) ablation to guide catheter navigation and placement. Technology improvements have significantly reduced fluoroscopy time, and subsequent radiation dose, necessary to perform successful ablations. However, there is still no amount of radiation exposure known to be completely safe.

Objectives: This study aimed to evaluate the progression of electrophysiological phenomena in a cohort of patients with paroxysmal atrial fibrillation (PAF) and persistent atrial fibrillation (PsAF).

Background: Electrical remodeling has been conjectured to determine atrial fibrillation (AF) progression.

Methods: High-density electroanatomic maps during sinus rhythm of 20 patients with AF (10 PAF, 10 PsAF) were compared with 5 healthy control subjects (subjects undergoing ablation of a left-sided accessory pathway).

Cigarette smoking is a major risk factor in the progression of atherosclerosis and has been shown to cause endothelial dysfunction, inflammation, and modification of lipid profile. However, its role in the pathogenesis of vulnerable coronary plaque remains unknown. We investigated the relationship between cigarette smoking and the development of vulnerable coronary artery plaque using virtual histology intravascular ultrasound (VH-IVUS).
