This heavily trafficked poster session featured posters focused on left atrial pressure waveform analysis, intracardiac echocardiography, pressure-guided cryoballon isolation of the pulmonary veins, radiofrequency ablation, atrial fibrillation due to mitral valve disease, a non-contact mapping system, and the mechanism of chronic atrial fibrillation. MDNG had the pleasure of meeting with some of the presenters, and summaries of their posters are provided below.

This brief presentation (roughly 25 minutes)—part of the “Groundbreaking Studies in the Practice of Cardiovascular Medicine: Circulation Editors’ Choices” session—featured Stefan H. Hohnloser, MD, who presented the results of a study that were published in the February 12, 2009 issue of the New England Journal of Medicine.

This abstract oral session featured several researchers who reviewed (quite quickly) the results of their studies, focused on such topics as spatiotemporal behavior of high dominant frequency, isoproterenol agents, mistakes in the use of amiodarone and anticoagulation management, and 3D transesophageal ultrasound. Highlights of these studies are provided below.
