MedStar Washington Hospital Center secured the highest possible distinction across three specific categories: coronary artery bypass grafting, mitral valve repair and replacement, and multiprocedural composite measures. Simultaneously, MedStar Union Memorial Hospital in Baltimore achieved three-star status for its performance in bypass surgery and combined procedures.

The Society of Thoracic Surgeons manages a national database containing over 10 million surgical records, representing more than 95% of adult cardiac surgeries performed domestically. This registry acts as a benchmark for clinical excellence, providing a transparent metric for patients navigating complex medical decisions.

Dr. Thomas MacGillivray, physician executive director of cardiac surgery at MedStar Health and a former president of the society, emphasized that the ratings validate the surgical teams' daily precision. By maintaining these standards, the hospitals solidify their position within a system that requires rigorous adherence to outcomes-based care.
