Onassis Cardiac Surgery Center

Since 1993, when it began operating thanks to a donation from the Onassis Foundation, the Onassis Cardiac Surgery Center (OCSC) has been a benchmark for cardiology and cardiac surgery in Greece. Having contributed decisively to reshaping the country’s cardiology landscape, it continues to set the standards for medical excellence to this day.

The OCSC is the largest specialized cardiology and cardiac surgery center in Southeast Europe, and the first hospital in Greece certified for the development and provision of healthcare services in these fields. Through a recent donation from the Onassis Foundation, its facilities have been fully upgraded with state-of-the-art, environmentally friendly infrastructure that not only serves the needs of patients but also fosters a functional and supportive environment for the medical and nursing staff.

At the OCSC, cardiac surgery is performed with the aid of hybrid operating rooms and minimally invasive techniques, reducing risk and accelerating recovery. At the same time, the Advanced Heart Failure and Mechanical Circulatory Support Department, unique in Greece, offers vital solutions for patients on the threshold of cardiac function.

The Center’s diagnostic approach is equally innovative: advanced imaging systems, fully digitized procedures, and real-time data analysis enable timely and accurate diagnosis. The integration of Artificial Intelligence into clinical practice enhances decision-making and tailors treatment strategies to the needs of each individual patient.

With a deep belief in the human dimension of medicine, the OCSC prioritizes the relationship of trust between doctor and patient. Each treatment path is accompanied by documented information and personalized guidance to empower patients and involve them in decisions concerning their own health.

The Onassis Cardiac Surgery Center, together with the Onassis National Transplant Center, constitute a national hub of medical innovation and expertise, placing Greece firmly on the global map of healthcare excellence.
