Dr. Valderrábano came to Houston from Los Angeles where he was director of the Implanted Devices Clinic at the UCLA Cardiac Arrhythmia Center and assistant professor of medicine at UCLA Medical Center.

Dr. Valderrábano received his medical degree from Universidad Autónoma de Madrid (UAM) School of Medicine in Madrid, Spain, and internal medicine training at UCLA. He completed his cardiology and electrophysiology training at Cedars-Sinai Medical Center in Los Angeles, where he was chief cardiology fellow. He then joined the faculty at the David Geffen School of Medicine at UCLA.

Description of Research

Dr. Valderrábano’s research and clinical interests focus on finding new and more effective treatments for atrial fibrillation, including epicardial mapping and ablation. His research has been funded by grants from the American Heart Association and the National Institutes of Health (NIH).
