A highly respected surgeon and gifted researcher, Dr. Horvath is the director of cardiothoracic surgery for Suburban Hospital. He is a graduate of the University of Chicago Medical School. He did his postgraduate surgical training at Brigham and Women's Hospital in Boston and was appointed director of the Cardiothoracic Surgery Research Laboratory at the National Heart, Lung, and Blood Institute of the National Institutes of Health. Dr. Horvath's clinical investigation interests include mitral valve repairs and aortic surgery.
"By collaborating with NIH and Johns Hopkins, Suburban Hospital assures patients that the care provided will be the most advanced available," says Dr. Horvath. "This is a true combination of high-tech and high-touch."
Originally from Boston, Dr. Corcoran, cardiothoracic surgeon at Suburban Hospital, received his undergraduate degree magna cum laude from Harvard University and completed his medical training and surgical residency at Georgetown University. Following his cardiothoracic surgery residency at Walter Reed, he remained there for 11 years, expanding and improving the clinical services, training opportunities and research endeavors. Dr. Corcoran also served as a senior policy advisor to the Office of the Surgeon General of the United States Army on all cardiothoracic surgery matters.
Dr. Corcoran has received numerous national awards, among them the LTG Claire L. Chenault Award for outstanding achievement in clinical practice and education in the NCA Tri-Services (Army/Navy/Air Force). He is a member of the Alpha Omega Alpha Honor Medical Society.
Dr. Greg Kumkumian
As the medical director of the Coronary Care Unit (CCU), Dr. Kumkumian leads the CCU staff in process improvement, focusing on core measures gathered by the State of Maryland, CMS and TJC. He also provides continuing education opportunities for CCU nurses and educators. A graduate of the George Washington University School of Medicine and trained at the University of Maryland in medicine and cardiovascular medicine, Dr. Kumkumian is board certified in internal medicine, cardiovascular diseases and interventional cardiology. Dr. Kumkumian recently joined the Bethesda-based cardiology practice of Maryland Heart, PC.
Dr. Siegenthaler is a cardiovascular surgeon at Suburban Hospital. He has more than 15 years of clinical and research experience in the field of cardiovascular surgery. Dr. Siegenthaler attended medical school at the University of Bern, Switzerland, completed a surgical residency at the University of Connecticut School of Medicine and completed a cardiothoracic surgery residency at the Texas Heart Institute in Houston. Besides the numerous cardiovascular and thoracic stent graft procedures he performs regularly, he also serves as a scientific and clinical volunteer at the National Heart, Lung, and Blood Institute of the National Institutes of Health.
NIH-Suburban MRI Center
Dr. Andrew Arai’s research focuses on advanced cardiovascular imaging to improve our understanding of myocardial ischemia and infarction. His special expertise is in cardiovascular magnetic resonance (CMR) imaging and close collaborations with physicists and engineers have led to a series of technical developments that are of interest to a wide range of cardiovascular problems. With respect to Pompe disease, real-time cine MRI methods have been developed that can rapidly assess relative contributions of diaphragmatic motion versus chest wall excursion with respect to breathing. Real-time cine MRI methods have been developed that can feature retrospective sorting of raw k-space data and the recorded ECG to automatically create high-quality, high temporal resolution, gated cine MRI without the need for breatholds. These methods will be useful in assessing cardiac response to treatment of Pompe disease and other conditions.
