Catheter Ablation of Atrial Fibrillation: Emerging Technologies
November 18th 2009This abstract poster session featured the topics of left atrial scar remodeling, closure of gap lesions, incidence of complete circumferential scar of the pulmonary vein antra, contact force mapping and ultrasound, antral isolation of pulmonary veins, radiofrequency ablation versus visutally guided laser balloon ablation, regional differences in left atrial wall thickness, and more. Highlights of these research posters are offered below.

Atrial Fibrillation: Bench to Bedside
November 17th 2009This session focused on the current state of practice for atrial fibrillation (AF) ablation; the pathophysiology of AF, including genetics, atrial structure, and neurologic input; and clinical and epidemiological insights into imaging AF substrate.

Echocardiography in Clinical Syndromes: Atrial Fibrillation
November 17th 2009This abstract oral session, featuring presenters who were given 15 minutes to review their research, provided attendees with information on the E/e’ ratio as a prognostic predictor in patients with atrial fibrillation (AF), the association between atrial and ventricular ECG findings and cardiac circulating biomarkers, stiffness of the left atrium, left atrial function as a predictor of first AF in older adults, and the mechanism of improvement of cardiac function in patients with AF. The studies are reviewed here.

Atrial Fibrillation: Mechanisms and Implications for Ablation
November 17th 2009This abstract session featured presenters for studies that focused on the importance of atrial surface area and refractory period in sustaining atrial fibrillation (AF), mechanisms of CFAE formation in the posterior left atrium during induced AF, the left atrial ganlionated plexus, and complex fractionated atrial electrogramm versus liner ablation for persistent AF.
