Abstract Aims The Atrial Fibrillation Ablation Pilot Study is a prospective registry designed to
describe the clinical epidemiology of patients undergoing an atrial fibrillation (AFib) ablation�…

Background—In patients with atrial fibrillation (AF), the risk of thromboembolic events (TEs)
is variable and is influenced by the presence and number of comorbid conditions. The effect�…

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Patients with AF have up to
seven-fold higher risk of suffering from ischemic stroke. Better understanding of etiologies of�…

Background—Atrial fibrillation (AF) is frequently initiated from pulmonary veins (PVs), but
little is known of the electrophysiological properties of PVs. Methods and Results—Two�…

Many patients with atrial fibrillation have substantial symptoms despite ventricular rate
control and require restoration of sinus rhythm to improve their quality of life. Acute�…

PURPOSE: To evaluate and classify the various drainage patterns of the pulmonary veins as
depicted with thin-section chest computed tomography (CT). MATERIALS AND METHODS�…

Methods and apparatus are provided for thermally-induced renal neuromodulation.
Thermally-induced renal neuromodulation may be achieved via direct and/or via indirect�…

Aims To investigate the effectiveness of additional substrate modification (SM) by left atrial
(LA) linear lesions as compared with pulmonary vein isolation (PVI) alone in patients with�…

Methods and apparatus are provided for treatment of heart arrhythmia via renal
neuromodulation. Such neuromodula tion may effectuate irreversible electroporation or�…

Background—It has recently been recognized that atrial fibrillation can originate from focal
sources in the pulmonary veins (PVs). However, the mechanisms of focal atrial fibrillation�…
