Jonas Cooper, MD, MPH, FACC
Jonas Cooper, MD, MPH, FACC, is a board-certified cardiac electrophysiologist with extensive experience in the diagnosis and treatment of arrhythmias (irregular heartbeats). His electrophysiology expertise includes surgical placement and management of pacemakers, defibrillators and cardiac resynchronization devices, as well as minimally-invasive ablation of cardiac arrhythmias such as atrial fibrillation, supraventricular tachycardia (SVT) and extra heart beats (PVCs).

Dr. Cooper received his medical degree at Washington University School of Medicine and his public health degree from Harvard University. He completed his clinical cardiac electrophysiology fellowship at Barnes-Jewish Hospital, was on faculty in the Department of Medicine at Washington University School of Medicine and has lectured and published various scholarly articles on electrophysiology.

Dr. Cooper's practice specialties include: heart electrical illness, home heart monitoring, heart palpitations, pacemakers, defibrillators, cardiac resynchronization, devices for heart failure, rhythm devices, cardiac ablation, atrial fibrillation, atrial flutter, supraventricular tachycardia (SVT), premature ventricular contractions (PVC), cardiac arrest and prevention of sudden cardiac death.

J. Mauricio Sanchez, MD, FHRS
J. Mauricio Sanchez, MD, FHRS, is board certified in cardiovascular disease, cardiovascular electrophysiology and internal medicine. He is a Fellow of the Heart Rhythm Society and the American College of Cardiology.

Following graduation from Vanderbilt University as a Chancellor Scholar, Dr. Sanchez received a medical degree from The University of South Florida College of Medicine in 2000, where he earned the Academic Excellence Award, the Internal Medicine Award, and the Semmelweis Award, and was inducted into the Alpha Omega Alpha Honor Medical Society.

He completed his internship, residency, cardiology fellowship and electrophysiology fellowship at Barnes Hospital - Washington University School of Medicine. He was awarded the Rising Star Award in Cardiovascular Research by Washington University School of Medicine and The Clinical Scientist Training & Research Program award, and was an American College of Physicians Research Poster Competition and American Heart Association Laennec Society Young Clinician Finalist. He has authored numerous articles and abstracts in medical journals, and has testified as an expert to the FDA regarding the Watchman left atrial appendage occluder device. Dr. Sanchez has been elected a St. Louis Best Doctor annually since 2009.

Dr. Sanchez' interests include atrial fibrillation and complex ablation for ventricular tachycardia and stroke prevention without anticoagulation using left atrial appendage occluder devices.

One treatment option for atrial fibrillation is catheter ablation, in which heat or cryotherapy can help fix an irregular heartbeat. St. Luke's electrophysiologist J. Mauricio Sanchez, MD, FHRS, uses fluoroless catheter ablation to treat arrhythmias in patients with atrial fibrillation. Instead of the fluoroscopic imaging traditionally used to guide catheter positioning, Dr. Sanchez uses advanced three-dimensional mapping technology.

Fluoroless catheter ablation is a groundbreaking technique that significantly reduces exposure to radiation for patients, physicians and staff. Since 2014, Dr. Sanchez has performed more than 1,000 ablations without fluoroscopy, and he's authored two chapters in the recently published cardiology book Fluoroscopy Reduction Techniques for Catheter Ablation of Cardiac Arrhythmias.
