TriStar Centennial October 20, 2017

Nashville, Tenn. — TriStar Centennial Medical Center announced today the completion of Middle Tennessee’s first procedure utilizing the Tryton Side Branch Stent to treat a coronary bifurcation lesion involving a large side branch 2.5 mm or greater. The procedure was performed at TriStar Centennial Heart and Vascular Center led by Dr. Paul Myers in collaboration with Dr. Jeffrey Webber, interventional cardiologists with Centennial Heart.

“TriStar Centennial is a national leader in cardiovascular care, utilizing the latest heart stent technology to treat high-risk cases of coronary artery disease,” said Dr. Myers. “This innovative and comprehensive approach allows us to treat patients with complex and high-risk blockages that involve arteries with important larger branches off the main heart artery.”

Coronary artery disease, the leading cause of death in the United States in both men and women, often results in the buildup of plaque at a site where one artery branches from another, also known as a bifurcation. Approximately twenty to thirty percent of all patients undergoing percutaneous coronary intervention (PCI) to open blocked arteries have a bifurcation lesion. Provisional stenting of the main branch is the current standard of care, but in many cases the side branch is not stented and can be compromised by shift of plaque from the main vessel into the side branch.

Dr. Myers notes that the side branch stent allows for total accommodation of the anatomy of the bifurcation without blocking the blood flow to the smaller vessels. The end result is greater predictable patient outcomes with less likelihood of artery plaque shift into larger side branches after a stent implantation.

“The utilization of this new technology demonstrates our cardiac team’s commitment to being a leader in caring for the heart health needs of our community and improving the quality of life of our patients,” said Scott Cihak, President and Chief Executive Officer at TriStar Centennial. “Our physicians continue to provide excellent care in terms of compassion, patient satisfaction and quality outcomes.”

The Tryton Side Branch Stent is a cobalt chromium stent based on Tri-ZONE® technology engineered to provide complete lesion coverage. It is deployed in the side branch artery using a standard single wire balloon-expandable stent delivery system. A conventional drug eluting stent is then placed in the main vessel. In February 2017, the Tryton Side Branch Stent became the first dedicated bifurcation stent to receive regulatory approval in the United States.
