4/1/2014 ECGI IMAGING Benefits Ablation for Ventricular Tachycardia

By Mary Jo Blackwood, RN, MPH

This procedure, called three-dimensional electroanatomic mapping, is effective
at identifying the target area, but it is invasive and requires a series of ventricular tachycardia beats to isolate the target. Washington University electrophysiologists, who perform more than 100 cases of ablation for VT every year, are now studying a new mapping technology that was developed in CBAC Director Yoram Rudy's laboratory.

This piece was published as a cover story for the Barnes Jewish Hospital's winter 2014 newsletter and features CBAC members Mitchell Faddis, M.D., Ph.D., Dan Cooper, M.D. with figures by graduate student Junjie Zhang

Gene testing for heart diseases now available

According to CBAC member Philip Cuculich, MD and one of the cardiologists involved in the development of the test, “Results from this test can help us refine diagnoses and allow us to personalize management and treatment of our patients... The results also may help family members of affected patients decide if they want to be tested to see if they are at risk for developing the disease.”

What’s Next: Beyond the EKG, to a Hypersensitive Heart Monitor

by Anne Eisenberg (NY Times)

Dr. Yoram Rudy, former professor of Biomedical Engineering at Case Western Reserve University, and current Director of the Cardiac Bioelectricity and Arrhythmia Center (CBAC) at Washington University in St. Louis, has, over the past 20 years, developed a unique method of electrocardiographic imaging (ECGI) that provides a noninvasive and detailed technique for recording electrical activity of the heart. This new method has great potential of one day helping to identify and diagnose patients at high risk of sudden cardiac death and life-threatening arrhythmias.
