Texas Health Dallas Cardiologist Joins International Panel of Experts at Summit

The two-day summit addressed leading issues surrounding the complex Ross procedure and included discussion of current peer-reviewed data about patient outcomes. The Ross procedure is a highly complex heart surgery, in which a patient’s diseased aortic valve is replaced with his or her own pulmonary valve. The patient’s pulmonary valve can then be replaced with a cryopreserved human valve.

“It’s a tremendous honor for Dr. Harper to be invited to such a prestigious conference,” said Jon Gardner, administrative director of the Heart & Vascular Service Line at Texas Health Dallas. “It reflects the high esteem in which he is held nationally. His skills and expertise are great assets to our patients and other physicians on our medical staff.”

The use of cryopreserved human pulmonary valves was cleared by the FDA in 2008 for use in cardiac reconstruction procedures, including the Ross procedure. In children and young adults, or older particularly active patients, this procedure offers several advantages over traditional aortic valve replacement with manufactured prostheses.

“Evidence suggests that it’s a good alternative to using manufactured prosthetic valves in some patients,” he said. “While there have been positive signs, we need to continue analyzing the latest information to ensure we’re doing what’s best for our patients.”

As a heart failure expert, Harper takes care of patients with cardiac valve problems, including diseased aortic valves, in addition to other types of heart disease.

The Ross Summit included cardiologists from the world’s leading medical centers, including the DeBakey Veterans Affairs Medical Center (Houston) University of Padova Medical School (Italy), Foch Hospital (France), Imperial College London Heart Science Center (United Kingdom), Emory University (Atlanta), German Heart Institute (Berlin), and the Cleveland Clinic (Ohio).
