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 350 Major 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.

Target Diseases

Valvular heart disease (aortic stenosis / regurgitation, mitral stenosis / regurgitation), ischemic heart disease, thoracic and thoracoabdominal aortic aneurysm, adult congenital heart disease, arrhythmia, TAVI and heart failure(VAD, cardiac transplantation)

Strong Fields

Our department specializes Cardiac and thoracic aortic surgery. We perform about 350 surgeries per year mainly for valvular heart diseases, ischemic heart disease, and thoracic aortic aneurysm. We also perform ventricular asist device implantation and heart transplantation for patients with severe heart failure.
Transcatheter aortic valve replacement (TAVR) Transcatheter mitral valve repair, hybrid aortic repair(combination of open surgery and stentgrafting) and removing of pacemaker leads with laser sheath has also been performed. We establish large scale clinical database and perform clinical research works in order to improve surgical outcomes. Many manuscripts have been published on worldwide journals about clinical studies for thoracic aortic surgery, valvular surgery, or surgery for atrial fibrillation. Retrograde cerebral perfusion as brain protection for aortic arch surgery is our original work, which has confirmed first in the world.

Clinical Results

Introduction to Nagoya university Departments of cardiac surgery Vascular surgery and Cardiology / Heart and aortic team

Cardiac surgery represents the final line of defense in protecting the heart. In our department, we specialize in addressing valvular heart disease, ischemic heart disease, aortic disease, and congenital heart disease.

We excel in minimally invasive cardiac surgery (MICS), incorporating robotic techniques when applicable. Additionally, our services include transcatheter aortic valve replacement (TAVI, TAVR, or mitraclip) and aortic stent graft surgery. Moreover, transcather closure of ASD is also available in our hospital. Conversely, we actively pursue complex surgeries for intricate heart diseases where minimally invasive approaches prove insufficient. With each treatment modality carrying its own set of advantages and disadvantages, we ensure transparent, understandable explanations and tailor the optimal treatment plan for each patient.

Furthermore, as the largest general hospital in the Nagoya Area, we offer comprehensive care for patients with comorbidities alongside their cardiac or aortic conditions.

The majority of our department's staff surgeons are proficient in English, with some having received training overseas.

As a general rule, when foreign patients without Japanese public medical insurance wish to receiv medical services from our hospital, we ask that they contact us through the organizations listed below,in order to proceed with diagnostic and treatment processes in a safe manner, and to facilitate the smooth completion of various administrative processes such as immigration procedures.
