Legacy Heart Center was formed more than 25 years ago, when Dr. Waenard Miller and Dr. David A. Schwartz combined their practices to create the Texas Regional Heart Center. In anticipation of a planned expansion to a new facility in Plano’s Legacy Park in April of 2005, the medical practice renamed itself Legacy Heart Center in 2003. Legacy Heart Center has grown from two cardiologists over 25 years ago to today’s staff of 17 cardiologists and more than 100 health and administrative professionals.

With its move to a new, 43,000 square-foot facility on Preston Road, the Center added a LightSpeed computed tomography (CT) system to its array of advanced cardiac diagnostic testing and treatment services, becoming the first private cardiology practice in North Texas with the innovative CT scanner.

The LightSpeed scanner, which is manufactured by GE Medical Systems, allows Legacy Heart Center cardiologists to non-invasively capture exceptionally high-resolution images of vascular structures, the heart and coronaries in fewer than five heartbeats.

It provides images that allow cardiologists to complete a thorough, non-invasive cardiac exam that will show blockages in the coronary arteries, the pumping action of the heart, the blood flow in the heart muscle and provides a coronary calcium score that can be used to assess a heart disease risk, and do it all in less than five heartbeats.

Legacy Heart Center’s nuclear laboratory is accredited by the Intersocietal Commission for the Accreditation of Nuclear Laboratories (ICANL), the echocardiography lab is accredited by the Intersocietal Commission for the Accreditation of Echocardiography Laboratories (ICAEL), and the Computed Tomography lab is certified by Intersocietal Commission for the Accreditation of Computed Tomography Laboratories (ICACTL).

Both the nuclear and the echocardiography labs are among the first laboratories in the United States, Canada and Puerto Rico to be recognized for a “commitment to high quality patient care and diagnostic testing,” according to both ICANL and ICAEL.

The cardiologists at Legacy Heart Center strive to be leaders in the advancement of cardiovascular care. They participate in many research trials and studies to help ensure the most innovative care is available to their patients. These research trials involve a variety of new pharmaceuticals, medical devices and procedures related to advanced cardiac care.

Our board certified cardiologist are on staff at Baylor Regional Medical Center at Plano, The Heart Hospital Baylor Plano, and Baylor Medical Center at McKinney.​
