Kathleen McDowell, a PhD student in the Dr. Natalia Trayanova's lab, was the winner of the Jos Willems Young Investigator Competition at the 2012 International Society for Computerized Electrocardiology (ISCE) meeting, in Birmingham, Alabama. Kathleen presented her recenty study, "Investigating the Arrhythmogenic Effects of Atrial Fibrosis in Patient-Specific Models". The study uses a novel computational model of the human left atrium, constructed from MRI scans of an atrial fibrillation patient. The model incorporates realistic structural and electrophysiological heterogeneity, including accurate fibrotic lesion geometry obtained from late gadolinium enhancement MRI. This model was used to investigate the mechanisms which underlie the breakup of pulmonary vein ectopic waves in the fibrotic atrium.

Jason Bayer, a PhD student in Dr. Trayanova's lab, has been awarded an American Heart Association predoctoral fellowship. Jason's research is part of an ongoing collaborative study with Dr. Sanjiv Narayan at the University of California, San Diego, that focuses on elucidating the underlying mechanisms of T-wave alternans in human heart failure. More specifically, he will be utilizing a combined clinical and computational modeling approach to investigate the role of cellular alternans in T-wave alternans that precede lethal ventricular arrhythmias. The overall goal of the research is to optimize T-wave alternans testing and risk stratification of arrhythmia vulnerability in patients to improve the success and economics of arrhythmia prevention. The duration of the award is from July 1, 2010 to June 30, 2012.
Jason Bayer has been selected as a finalist in the Young Investigator Competition at the International Congress of Electrocardiology in Lund, Sweden, June 2010. The title of his talk will be "Spacially discordant alternans in action potential voltage underlie T-wave alternans in human heart failure."

National Research Service Awards (NRSA) from NHLBI worth five years of research training support.
- Hermenegild Arevalo won the award to support his project "Image-based models that predict arrhythmia morphology in post-infarction hearts." The goal of the project is to examine the ventricular tachycardia reentrant pattern in the infarcted heart and its dependence on the morphology of the infarct scar.
- Jason Constantino's research project, "Image-based models of electromechanics in normal and failing hearts," aims to characterize the relation between electrical activation and mechanical contraction in normal and failing hearts under different loading conditions. The new insights gained from this project are expected to ultimately lead to rational optimization of cardiac resynchronization therapy (CRT) delivery and improvement in selection criteria for identifying viable CRT candidates.
