Cardiac Surgery Department
About Us
With about 400 cardiac and thoracic great vessel surgeries performed annually, the Department of Cardiac Surgery is one of the leading institutions of Japan. Minimally invasive techniques such as off-pump bypass surgery without using a heart-lung machine have been applied to many patients.

Treatment plans are determined at clinical conferences based on detailed examination and discussion.
Joint conferences are also held regularly with the Department of Cardiovascular Medicine and/or the Department of Pediatrics to discuss cases referred by other institutions.
Medical services
Prescheduled surgeries are performed three days each week along with emergency surgeries.
The department consists of three teams specializing in different areas: adult heart disease (ischemic heat disease, valvular heart disease, arrhythmia disorders, severe heart failure), aortic disease (thoracic aneurysm, aortic dissection, etc.); and congenital heart disease.
Outpatient services are provided every week day.
Areas of expertise
Diseases
- Ischemic heart disease
- Valvular heart disease
- Severe heart failure (such as idiopathic and ischemic cardiomyopathies)
- Infective endocarditis and aneurysms
- Thoracic aortic aneurysms and dissection
- Congenital heart diseases (neonate, infant, child and adult)
- Complex cardiac anomalies, such as hypoplastic left heart syndrome
Treatment methods
- Off-pump or beating-heart coronary artery bypass grafting
- Mitral valvuloplasty and valve-sparing aortic root replacement
- Cardiac transplantation and auxiliary artificial heart
- Curative treatment of infection, using allograft heart valves and blood vessels
- Arch replacement and low-risk surgical procedures for extensive aortic aneurysms
- Norwood and Fontan procedures
In our department, about 90% of patients requiring coronary-artery bypass surgery undergo off-pump coronary artery bypass (OPCAB) surgery. In almost all patients with mitral insufficiency, valvuloplasty is performed.
The Maze procedure is also frequently performed to treat arterial fibrillation. Our department is one of the departments in Japan where valve-sparing aortic root replacement is most frequently performed to treat annuloaortic ectasia.
Graft replacement for aortic arch and thoracoabdominal aortic aneurysm that protects the brain and spinal cord are also performed in many patients. Using these procedures, highly successful surgical results have been achieved in patients aged 75 and older as well as in serious cases with complications.
As for congenital heart disease, many surgical procedures such as the Norwood procedure, the Jatene procedure, and the Fontan procedure have been performed successfully for complex heart malformations. Minimally invasive surgery that takes appearance into consideration and surgery without blood transfusion are also performed.
Our department has been approved as a heart transplant facility and has performed heart transplants for 59 patients (48 in Japan and 10 at overseas facilities) as well as ventricular assist device (VAD) surgery. We have the most successful VAD implantation record in Japan.
