In Cardiovascular Medicine, a total of 55 physicians specialized in cardiovascular medicine are committed to diagnosis, treatment, and prevention of all cardiovascular diseases, making full use of advanced medical techniques. We also accept emergency patients with acute myocardial infarction, cardiac failure, etc., on the basis of a 24-hour emergency system in cooperation with the Trauma and Acute Critical Care Center. Minimally-invasive examinations including multi-slice computed tomography and myocardial scintigraphy are first performed for diagnosis of coronary artery diseases on patients with ischemic heart disease, followed by coronary arteriography and percutaneous coronary intervention. Our section, which is designated as a certified heart transplantation center, treats all the patients with minor to severe cardiac failure with sense of mission that we serve as the last relief for patients in the cardiovascular medicine field in Japan. We actively treat patients with intractable arrhythmia by catheter ablation, pacemaker implantation, and defibrillator implantation. Many physicians specialized in various cardiovascular areas work in this section, making the highest-quality consultation in the individual areas in Japan. Please feel free to contact us to treat cardiovascular diseases including acute-stage diseases.


Our hospital, which is designated as a certified heart transplantation center, actively treats patients with severe heart failure. We make full use of a variety of diagnostic imaging techniques to provide a wide range of medical care services from medications including β blockers to advanced non-pharmacological treatments such as biventricular pacing (CRT) and catheter ablation, as well as ventricular assist device implantation and cardiac transplantation in cooperation with Cardiovascular Surgery. We also perform numerous and various clinical trials in our own facilities, and in collaboration with national and overseas facilities.
Total number of inpatients in our department in 2016 was 1217 patients, with transfers referred from all over Japan (80 cases). In the care of heart failure, we have examined intractable diseases such as dilated cardiomyopathy (83 hospitalized cases) and hypertrophic cardiomyopathy (including dilated phase, 27 hospitalized cases), and we perform detailed examinations, focusing on myocardial biopsies (275 cases in 2016). For arrhythmia, we perform all kinds of treatments from pacemaker implantations (92 cases in 2016) to ablation treatment (104 cases in 2016), and also perform lead extraction using an excimer laser for pacemaker infections (14 cases in 2016). In addition, for ischemic heart disease we perform coronary artery catheter treatment (246 cases in 2016), including highly difficult cases such as chronic total occlusion (24 cases in 2016), and use new diagnostic and treatment methods which actively incorporate the up-to-date diagnostic imaging (320-raw of multi-slice CT, intravascular ultrasound, OCT, MRI). We also actively incorporate metabolic approaches to preventing coronary artery disease and its recurrence, and aim for a fundamental therapy against the accumulation of arteriosclerosis risk factors represented by metabolic syndrome. Further, as a heart team together with Cardiovascular Surgery, we are top ranked in Japan in the annual number of transcatheter aortic valve implantations (TAVI) performed on high-risk patients with inoperable severe aortic (valve) stenosis (96 cases in 2015 and 96 cases in 2016).

Considerations in referring your patients to Cardiovascular Medicine

Outpatient Clinic specialized for First-time visitors has been expanded, which now opens daily morning. Also, the outpatient specialty teams including "Hearrt Failure", "Plumonary Hypertension", "Hyperlipidemia", and "Structural Heart Diseases" has been launched in addition to current teams for "Ischemia", "Valvular disease", and "Arrhythmia". Other outpatient teams perform examinations and treatment on patients with all cardiovascular diseases.
