We protect your heart with our 24-hour-available team medical care system

The Department of Cardiac Surgery is one of the leading institutions of Japan in the filed of cardiovascular surgery . Approximately 300 Cardiac, or thoracic aortic surgeries were performed annually by the department. Minimally invasive techniques may be applied in selected patients. Some surgeons were trained abroad, and fluent in English. Professional translators were also available.

Medical Care System

We provide 24-hour quick response service with our team medical care system consisting of 15 staff members; an on-duty doctor is always available both during the day shift and the night shift.
