Treatment Methods (Comprehensive Treatment for Ischemic Heart Disease, Valvuloplasty/Valve Replacement for Elderly Patients)

At Juntendo University Hospital Heart Center, we practice cardiovascular team medicine involving the collaboration of not only internists and surgeons, but also many other medical staff, offering high-quality, comprehensive treatment from initial therapy to rehabilitation based on the principles of sports medicine.

We are able to make the best choice for each individual patient from among the various surgical and medical options used to treat ischemic heart disease. In the Department of Cardiovascular Surgery, we are well known for performing off-pump coronary artery bypass (OPCAB) surgery, which although difficult, results in a reduced burden on the patient. Dr. Atsushi Amano, one of the world’s most renowned and experienced cardiac surgeons, has performed over 3,300 OPCAB surgeries with some of the best results in the world. He performs minimally invasive, highly curative treatment using long-lasting arterial grafts. The Department of Cardiovascular Medicine, directed by Dr. Hiroyuki Daida, performs a large number (500–600) of percutaneous coronary intervention (PCI) procedures each year, with a high success rate, making it the most effective choice among a variety of devices such as stents and rotablators in accordance with the state of the lesions to be treated.

Of the various types of valvular disease, aortic valve stenosis can be diagnosed at an early stage by cardiac ultrasound, enabling prognosis to be greatly improved by valve replacement. The department is currently attempting to increase safety and effectiveness by using original CT assessment techniques. The number of elderly patients with multiple organ failure has been increasing in recent years, and those at higher risk due to problems in other organs can undergo treatment for those conditions first in collaboration with other departments to lower their risk before valve replacement is carried out. The Department of Cardiovascular Medicine is in the preparatory stages of offering transcatheter aortic valve replacement (TAVR), in which a catheter is used to replace the aortic valve in a minimally invasive manner. In cases of aortic root dilation with no valvular abnormality, we proactively performs the David procedure, which conserves the patient’s own valves. It has also long been performing valvuloplasty in cases of mitral valve insufficiency, with impressive long-term results.

Juntendo, founded in 1838, was the first educational institution to teach Western medicine in Japan in combination with medical institutions, and boasts a long history and tradition dating back over 170 years.

The Departments of Cardiovascular Medicine and Cardiovascular Surgery are the oldest specialist departments in Japan, and the Heart Center was formed in 2006 to enable even closer collaboration of two departments, allowing them to offer optimum tests and treatment for each individual patient. A wide range of medical staff are also involved in the formation of specialist teams capable of determining the most efficient treatment strategy from the patient’s standpoint. In addition, patients transfer seamlessly to cardiac rehabilitation after surgery, with the aim of improving long-term prognosis, including secondary prevention.

Our center gathers and shares data on the long-term prognosis of patients, and this information is being utilized in the choice of more appropriate treatment options both today and for the future. A hybrid operating room for joint use by both departments for procedures such as endovascular treatment is currently under construction within the hospital. This will enable the adoption of more collaborative, complementary, and competitive approaches, and is expected to improve the quality of treatment even further. The introduction of robot-assisted surgery is also planned.

Infection control measures and collaboration with other departments are well in hand, with the aim of allowing our center to not only “cure” disorders, but to also increase patient satisfaction by taking factors such as appearance after the surgical scar has healed into account.

Juntendo's mission lies in the spirit of jin, which means “I exist as you exist, with a heart that is considerate and cherishes others.” At our center, the doctors as well as the nurses, clinical technicians, clerks, and entire staff are aware that they are members of a Heart Team. They are striving both to provide high-quality treatment and to maintain a comfortable therapeutic environment for patients. Our aim is to use our wealth of experience to provide uniformly high-quality treatment, and we hope international patients will continue to choose to undergo comprehensive treatment in our center, not only with a view to the short-term success of treatment, but also to achieve a more comfortable life over the long term.
