Premier Health Hospitals Earn Highest Ratings for Heart Surgery

DAYTON, Ohio (June 30, 2025) – Premier Health’s Atrium Medical Center and Miami Valley Hospital have earned the highest possible rating — three stars — from The Society of Thoracic Surgeons (STS), placing them among the top-performing cardiothoracic surgery programs in the United States and Canada.

Atrium Medical Center earned its first-ever 3-star rating for coronary artery bypass grafting (CABG), commonly known as heart bypass surgery, a milestone that highlights exceptional outcomes and a team-based approach to care.

Miami Valley Hospital achieved a 3-star rating in aortic valve replacement combined with coronary artery bypass grafting (AVR-CABG), a recognition earned by only 4% to 7% of programs nationwide, according to STS.

Both hospitals also received 3-star ratings in overall multiprocedural cardiac surgery, a new and highly selective STS category that reflects performance in complex cases such as bypass surgery combined with multiple valve procedures.

“Receiving the STS three-star rating reflects Premier Health’s commitment to high-quality care and patient safety,” said Roberto Colón, MD, Premier Health chief medical officer. “It’s a meaningful recognition of the skill, compassion, and teamwork our caregivers bring to every patient, every day. When someone needs heart surgery, it can be an overwhelming time for them and their family. Knowing they have access to the highest-quality care right here in their community can bring a great deal of comfort. We’re proud to provide that peace of mind.”

The STS 3-star rating is the organization’s highest, reflecting superior outcomes in areas like mortality, complications, and adherence to best practices. Ratings are based on data submitted to the STS Adult Cardiac Surgery Database over a three-year period, from January 2022 through December 2024.
