In the past, open heart surgery for heart valve repair required opening the patient’s chest. Today, world-class surgeons at CHI St. Luke’s Health–Baylor St. Luke’s Medical Center use minimally invasive techniques to make small “keyhole” incisions, which result in shorter surgeries, reduced hospital stays, faster healing, and minimal scarring.

Specializing in minimally invasive cardiac surgery, experts in the world-renowned Division of Cardiothoracic Surgery treat diseases within the heart and chest, which include the treatment of aortic aneurysms, heart valve disease, aortic valve stenosis, aortic valve regurgitation, mitral valve regurgitation and stenosis, and coronary artery disease (coronary bypass surgery). In addition, we:

  • Provide unparalleled clinical care and service in an environment consistent with the rapidly changing medical landscape.
  • Initiate, foster, and enlarge innovative cardiothoracic research programs.
  • Conduct educational programs that enrich the local, national, and worldwide surgical communities as well as produce the academic and clinical leaders of tomorrow.
