In Cardiovascular Medicine, a total of 50 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 mild to severe cardiac failure with sense of mission that we serve as the last relief for patients in the cardiovascular medicine field in Japan. In particular, we focus on diagnosis, prognosis prediction and treatment of cardiomyopathy, including advanced efforts. 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.

Features

Our hospital, which is designated as a certified heart transplantation center, actively treats patients with severe heart failure. Using a wide range of diagnostic imaging techniques, we provide differential diagnosis of cardiomyopathy, drug treatments such as β blockers, biventricular pacing therapy, and ablation, as well as actively working to support ventricular assist device implantation and cardiac transplantation as a team 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 2018 was 1185 patients, with transfers referred from all over Japan (56 cases). In the care of heart failure, we have examined intractable diseases such as dilated cardiomyopathy (84 hospitalized cases) and hypertrophic cardiomyopathy (including dilated phase, 35 hospitalized cases), and we perform detailed examinations, focusing on myocardial biopsies (272 cases in 2018). For arrhythmia, we perform all kinds of treatments from pacemaker implantations (91 cases in 2018) to ablation treatment and electrophysiological examination (174 cases in 2018), and also perform lead extraction using an excimer laser for pacemaker infections (18 cases in 2018). In addition, for ischemic heart disease we perform coronary artery catheter treatment (213 cases in 2018), including highly difficult cases such as chronic total occlusion (15 cases in 2018), 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 (143 cases in 2017 and 123 cases in 2018). We also perform percutaneous myocardial septal ablation for obstructive hypertrophic cardiomyopathy (6 cases in 2018) and catheter treatment (MitraClip) for severe mitral insufficiency (13 cases in 2018).

Considerations in referring your patients to Cardiovascular Medicine

We widely accept first visit patients who are referred from other hospitals, and have established a first-visit outpatient clinic every morning in order to improve our service, such as reducing the waiting time on the day. In order to provide more specialized medical care to patients who need it, specialized outpatient care has been expanded to include heart failure, pulmonary hypertension, lipids, transplants and congenital heart disease, in addition to the previous care for ischemia, pacemakers and valvular disease. For details, please refer to the latest outpatient doctor's schedule.
