Cardiovascular Medicine

Cardiovascular Medicine

The Department of Cardiovascular Medicine provides medical care for patients with heart disorders such as angina pectoris, myocardial infarction, heart failure, valvular heart disease, cardiomyopathy and arrhythmia; disorders of the aortas and peripheral vessels; and hypertension

Medical services

Approximately 1,700 patients are admitted to our department each year. A group of three doctors, including two specialists, are assigned to each patient. Each morning and afternoon, there are seven to eight doctors providing outpatient cares.

Diagnosis and treatment policy

An accurate assessment of the pathophysiology followed by prompt diagnosis and treatment are important in the care of patients with cardiovascular disorders. To meet this need, the Department of Cardiovascular Medicine provides roundthe-clock emergency services. The department also provides comprehensive treatment and care in close cooperation with other departments, with a particular emphasis on an individual patient-oriented approach.

Specialties

The department’s strength lies in the diversity of specialists in the cardiovascular area. Our hospital has been approved as a heart transplant center. Coronary angioplasty and catheter ablation for the treatment of arrhythmia are also provided

Target diseases

Ischemic heart disease (angina pectoris, myocardial infarction), cardiomyopathy (dilated, hypertrophic, etc.), heart failure, valvular heart disease, congenital heart disease, arrhythmia, hypertension, aortic diseases, peripheral vascular disease, etc.

Advanced treatments/ Specialized treatments

Severe heart failure, Heart transplantation

We are making a special effort to treat severe heart failure patients. Pre- and post-operative treatment is provided to heart transplant patients in cooperation with the Department of Cardiac Surgery.

Catheter ablation method

Radiofrequency energy emitted from the tip of the catheter is used to remove areas that are causing an arrhythmia.

Rotablator

The Rotablator, a coronary angioplasty system that uses a highspeed rotating diamond-tipped burr to abrade hardened lesions, is only employed at a limited number of hospitals.

Transcatheter aortic valve implantation (TAVI)

Severe aortic valve stenosis patients, especially with high risk, are treated by TAVI.

Implantable cardioverter defibrillator (ICD)

A device that is implanted in the patient’s chest to deliver electrical therapy immediately when serious arrhythmia is detected.

AMPLATZER Septal Occluder

A device, which is a standard of care for minimally- invasive atrial septal defect (ASD) closure is available.

The Marfan, pulmonary hypertension and adult congenital heart disease outpatient clinic

Outpatient care is available for patients with Marfan syndrome , pulmonary hypertension and adult congenital heart disease.
