The Cardiology division provides state-of-the-art medical care for children with heart disease and is pushing the frontiers to find improved diagnostic and treatment modalities for the future.  There are approximately fifteen board-certified pediatric cardiologists in the division, each with a special area of expertise within cardiology.  The Division provides services at Children’s Medical Center Dallas in an outpatient clinic (~6,500 visits/year), a 22-bed inpatient floor dedicated to cardiac patients, a 17-bed dedicated Cardiac Intensive Care Unit, two cutting edge catheterization labs for non-surgical intervention in children, and an echocardiography suite, including special areas for fetal echocardiography.  All electrocardiographic procedures are available including radiofrequency ablation of pediatric arrhythmias.  The Division has also enjoyed one of the highest success rates in heart transplantation.  Together with our surgical colleagues, we cared for children having nearly 450 open-heart surgeries in 2003.  The recent recruitment of Dr. Joseph Forbess as the new Director of the Division of Pediatric Cardiothoracic Surgery and the addition of Dr. Thomas Yeh to the surgical staff bring great excitement to the future of pediatric cardiology at UTSW. In addition to the full range of clinical activities, the Division has numerous prominent prospective clinical trials ongoing or recently completed.  Finally, we have been at the forefront of understanding the genetic control of congenital heart defects and maintain one of the leading efforts in the basic science of heart disease in children.
