Our department provides medical care for patients with heart disorders, vascular disorders, hypertension, congenital heart disease, etc. Please check our website https://cardiovasc.m.u-tokyo.ac.jp/ for further details.
Medical services
One resident and two specialist doctors are assigned to each patient. At night or during holidays, two doctors are on duty for emergency patients. Our facility is a member of the CCU network; therefore, we provide round-the-clock emergency services for conditions such as acute myocardial infarction.
Diagnosis and treatment policy
An accurate assessment of the pathophysiology followed by prompt diagnosis and treatment are important when caring for patients with cardiovascular disorders. Following the guidelines in combination with advanced treatment, we also provide comprehensive treatment and care in close cooperation with other departments, with particular emphasis on the individual patient-oriented approach.
Specialties
Our department’s strength lies in the diversity of specialists in the cardiovascular field. Our hospital is a heart transplant center, and there are special outpatient clinics for pulmonary hypertension, congenital heart disease, valvular heart disease, cardiomyopathy, and Marfan’s syndrome.
Target diseases
Heart failure, ischemic heart disease, cardiomyopathy, arrhythmia, valvular heart disease, congenital heart disease, hypertension, pulmonary hypertension, aortic diseases, peripheral vascular disease, etc.
Advanced treatments/ Specialized treatments
Severe heart failure, Heart transplantation
We make a special effort to treat patients with severe heart failure, including assessing the indication for heart transplantation, using a ventricular assist device, and treating patients after heart transplantation. Therapeutic strategy is discussed by “Heart team” comprising cardiac surgeons, nurses and medical engineers.
Catheter ablation method
Radiofrequency energy emitted from the tip of the catheter is used to remove areas that are cause arrhythmia.
Special percutaneous coronary intervention
The Rotablator, a coronary angioplasty system that uses a highspeed rotating diamond-tipped burr to abrade hardened lesions. Excimer Laser Coronary angioplasty system can vaporize thrombi and ablate plaques.
Transcatheter Aortic Valve Replacement (TAVR)
Patients with severe aortic valve stenosis, particularly those at intermediate to high risk, are treated by TAVR.
Left Atrial Appendage Closure (LAAC)
LAAC is a proven one-time procedure that reduces the risk of stroke in patients with non-valvular atrial fibrillation, and the risk of bleeding that comes with a long term oral anticoagulant use.
Implantable cardioverter defibrillator (ICD)
A device that is implanted in the patient’s chest to deliver electrical therapy immediately when serious arrhythmia is detected.
Excimer laser lead extraction
When needed, such as during device infection, the laser technique is used for lead extraction by vaporizing the scar surrounding the device lead.
Percutaneous closure of atrial septal defect (ASD)/ Percutaneous closure of patent foramen ovale (PFO)
Transcatheter closure for ASD and transcatheter closure for PFO related with cerebral embolism are available at our hospital.
