The Department of Cardiovascular Surgery provides surgical care
for adult heart and thoracic aortic diseases.
We understand that heart disease can be a source of great concern for patients and
their families, and we are committed to offering safe, reliable, and
patient-centered care.
Our treatment approach balances effective disease management with minimizing
physical stress. Not all patients require surgery; depending on the condition,
medical treatment or careful follow-up may be the best option. We place great
importance on clear communication so that patients can make well-informed decisions
about their care.
Cardiovascular treatment is delivered by a multidisciplinary Heart Team, working
closely with cardiologists, anesthesiologists, intensive care specialists, and
allied health professionals. Transcatheter aortic valve implantation (TAVI) is also
available, allowing us to tailor treatment strategies to each patient’s condition.
We collaborate closely with referring physicians and community hospitals to ensure
continuous care before and after treatment.
We offer comprehensive surgical treatment for adult cardiovascular diseases,
including ischemic heart disease, valvular disease, and aortic disease. Our main
procedures include coronary artery bypass surgery, valve surgery, and aortic
surgery.
Treatment plans are individualized based on each patient’s medical condition,
overall health, and lifestyle. For ischemic heart disease, we work closely with
cardiologists to determine the most appropriate timing and method of surgical
intervention. In valvular disease, valve repair is performed whenever feasible to
preserve native valve function.
For aortic stenosis, both surgical treatment and transcatheter approaches (TAVI) are
considered through Heart Team discussion. Aortic diseases such as aneurysm and
dissection are managed with open and endovascular techniques as appropriate.
Our care extends beyond surgery. We emphasize long-term follow-up and close
coordination with cardiologists and community physicians to support patients
throughout their recovery.
Depending on the condition, patients may be managed primarily by cardiology.
When needed, we work in collaboration with the Saitama Medical University
International Medical Center to provide optimal treatment.
Symptoms of major cardiovascular disease are shown below. Even if
one has some of these, it does not always imply surgery is indicated.
chest pain, anterior chest discomfort, shortness of breath, palpitation, dyspnea,
irregular pulse, back pain, etc.
enlarged cardiac silhouette on X-ray, abnormal findings on electrocardiogram, etc.

(1) Documents with as much information as possible are appreciated.
(2) Please feel free to fax or make a booking in advance, but they are not necessary.
Postoperatively, stable patients are usually referred back. Limited number of patient with special needs (physical condition, discretion, etc.) can be followed up at institutions we regularly visit or, rarely, at our Cardiology department.
Our department specializes in treatment for cardiac and thoracic
aortic diseases in the adult. Since workforce is still insufficient in comparison to
case volume, you can get bunch of clinical experience in this field if you become a
member. To be accredited as a board cardiovascular surgeon, however, experiences in
other fields (congenital, peripheral vascular) are also required. As this is a
member of Tokyo University cardiac surgery group, you can work for some other member
hospitals for a while.
You can get a degree of medical doctor (PhD).
On weekday, we usually start to work at 7:30 AM. There is no regular overnight duty.
On Sundays and holidays, stuffs take turn for daytime shift.
