Dr. Packer is also the International Principal Investigator of the recently funded NIH CABANA Pivotal Study. In this capacity he leads the consortium of centers directing the trial.
Dr. Packer is a Mayo Clinician Investigator. His translational work focuses on the mechanisms and ablation of atrial fibrillation and other cardiac arrhythmias, autologous fibroblast modulation of electrical impulse propagation in the heart, and the development of carbon particle catheter-free ablation of arrhythmias. His clinical work investigates 4/5 dimensional integrated image guided ablation, and the development of new energy sources for the modification of cardiac tissue. His work has been funded in part by private foundations, the American Heart Association, and the NIH. Dr. Packer holds US and European patents in the development of intracardiac ultrasound and 4/5D imaging.
