Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Use of Cardiac MR before and after Electrophysiology Procedures

Sunday, March 14, 8:39 AM - 8:52 AM   In this state-of-the-art imaging symposium, Joao A. Lima, MD, from John Hopkins University will elucidate how cardiac MR can help EPs before and after procedures. Lima penned a state-of-the-art paper on this topic back in 2004 in the Journal of the American College of Cardiology. Since the publication of that article, many technological advances have taken place regarding MRI and Lima has been at the forefront of that field. Attendees will surely learn how to best use cardiac MR to enhance procedural success and patient safety. 

Ablation not Antiarrhythmic Drug Therapy Should Be the First Line Approach for Paroxysmal AF

March 14, Sunday 8:00 AM to 9:30 AM   This session might be one of the more exciting gatherings of electrophysiologists at ACC.10. It will pit experts against experts, debating the pros and cons of particular therapies on particular patients. Are there specific benefits of catheter ablation relative to drug therapy for some patients? How can EPs identify and distinguish which patients with paroxysmal atrial fibrillation (AF) are optimal candidates for ablation or drug therapy? While these questions may not be resolved, they will be thoroughly discussed, with antagonist and protagonist case witnesses lending their support. In addition, the audience can join the fun via the audience response system.

ACC Education Sessions Preview: Electrophysiology

The field of electrophysiology (EP), particularly pertaining to ablations, has been reported to be growing faster than coronary interventions, and there are no signs that it will slow down. While the volume of coronary cath procedures has remained somewhat flat over the past year, EP labs have been expanding and adding new technology. For this reason alone, it behooves attendees at ACC.10, which begins on Saturday, March 13, to take in some of the exciting EP lectures being presented at the conference.   One of the biggest topics in EP is whether transcatheter ablation should be the first-line treatment over anti-arrhythmic drugs in patients with atrial fibrillation (AF). First results of the pilot CABANA study, being released in a late-breaking clinical trial session, could potentially indicate a new direction for this debate (see below for session details).READ MORE

Radiology: Virtual colonoscopy safe, beneficial for patients with metallic stents

The use of CT colonography is usefuland safefor a preoperative exam of the proximal colon in patients who have been treated with metallic stents due to colon obstruction caused by colorectal cancer, according to a study published in the March issue of Radiology.

Circulation: ICD ventricular defibrillation testing affects cognitive function

A standard test of implantable cardioverter-defibrillators (ICDs) is linked to significant thought-processing problems that improve for most patients within a year after the device is inserted, according to a study published in the March 2 issue of Circulation: Arrhythmia and Electrophysiology.

Commentary: Atrial fibrillation strikes an electrophysiologist

Middle age introduces itself in many ways; one is atrial fibrillation (AF). My onset of AF seems to have coincided with a mountain bike accident in the woods of North Carolina that resulted in some cracked ribs.
