September 01, 2020

Chattanooga, TN – Parkridge Health System today announced the opening of two cardiac specialty practices: Centennial Heart at Parkridge, a full-service multispecialty practice specializing in diagnosing, managing and treating the full spectrum of cardiac and vascular disorders, and Centennial Cardiovascular and Thoracic Surgery at Parkridge, a surgical specialty group focusing on the surgical treatment of conditions affecting the heart and lungs. The practices will be located on the second floor of the Diagnostic Center at 2205 McCallie Ave., Chattanooga, TN, 37404.

The multispecialty practices are comprised of cardiologists, interventional cardiologists, cardiac imaging specialists, cardiothoracic surgeons and electrophysiologists, who will offer a wide range of treatments, ranging from medical management of cardiac disease and ablation for atrial fibrillation (Afib) to specialized interventional procedures for treating chronic total occlusion, leading-edge surgical techniques and percutaneous left atrial appendage closure device implantation to prevent stroke in patients who cannot take blood thinners. The addition of these two practices will allow Parkridge Health to treat the majority of cardiac conditions.

“It is a significant milestone to welcome such an esteemed group of physicians to a health system,” said Tom Ozburn, president and CEO of Parkridge Health System. “Centennial Heart at Parkridge is a tremendous win for the Chattanooga area, in terms of heart and vascular care, and we believe this group will reshape the landscape of cardiac care in our community. As heart disease continues to be the leading cause of death in the United States, we are thrilled to welcome this group of world-class specialists who are among the highest regarded physicians in our area. They will elevate the level of care we are able to provide and position us for continued growth in the coming years.”

“Centennial Heart at Parkridge marks a new era of cardiac care in Chattanooga,” said Alison L. Bailey, MD, FACC, chief of cardiology for Centennial Heart at Parkridge. “We have assembled a team of elite specialists who not only have the expertise to use the full spectrum of treatment options but also are committed to partnering with their patients to improve their cardiovascular health.”

Centennial Heart at Parkridge connects Chattanooga to the Centennial Heart network, which is based in Middle Tennessee and is also affiliated with HCA Healthcare. Such alignment brings a wider array of services and access to leading-edge technology to the community.
