About Dr. Leon

Research Focus:

Dr. Leon directs his investigational activities toward developing, testing and applying new diagnostic and therapeutic techniques for management of heart rhythm disorders.  Specific techniques include catheter ablation of ventricular tachycardia, supraventricular tachycardia, and atrial fibrillation.  He has also been extensively involved in the evolution of device therapy for the treatment of congestive heart failure and life threatening arrhythmia.  Some of this research also includes analyzing outcomes of various treatment strategies that utilize new technologies.  His clinical research activities have resulted in being selected to the following positions:

1. Primary National Investigator:  Primary Defibrillator Study, Guidant Corp. 1992

2. Co-Primary National Investigator:  InSync III Clinical Evaluation, Medtronic Corp. 1993

3. Executive Committee and co-Primary Investigator:  PROSPECT, Medtronic Corp. 2004

4. Steering Committee, ESTEEM Clinical Research Trial, Guidant Corp. 2005

5. National Co-Chair, Cardiac Resynchronization in Narrow QRS, Guidant Corp. 2006
