Catheter Ablation of Atrial Fibrillation (AF)

AF is the most common heart arrhythmia. Medications are only modestly effective, so we are working on catheter-based approaches to treat AF by directly cauterizing the tissue causing the problem. We are working with other approaches to do this catheter ablation procedure using laser energy or cryo energy (freezing tissue).

Left Atrial Appendage Closure

People with AF are at high risk for stroke-thus most people receive Warfarin Rx. We are working on approaches to use catheters to close the left atrial appendage. Then, patients would be protected from stroke without having to take Warfarin (Coumadin).

Catheter Ablation of Ventricular Tachycardia (VT)

Ventricular tachycardias are the most common cause of sudden death. The standard approach is to place defibrillators (ICDs) in patients at high risk for sudden death. We are working on approaches to use catheters to cauterize (ablate) the tissue responsible for these arrhythmias.
