Greetings
Cardiology offers cutting-edge medical care. We offer the world's most advanced CT, MRI, nuclear medicine, and ultrasound imaging. In the coronary artery area, we offer cutting-edge treatment using world-leading intravascular ultrasound (IVUS) and optical coherence tomography (OCT) imaging equipment. Our nationally leading physicians provide interventional procedures for coronary artery (PCI), peripheral vascular (EVT), carotid artery (CAS), and renal artery (PTRA). Our arrhythmia treatments include atrial fibrillation ablation and implantable cardioverter defibrillators. We also actively treat structural heart disease, primarily with percutaneous aortic valve replacement and catheter-assisted mitral valvuloplasty. We are also seeing an increase in the number of catheter-assisted atrial septal defect closures and chronic thrombotic pulmonary arterial hypertension (CTEPH) cases. We are attracting attention from around the world, attracting many international physicians seeking guidance and observation, making us undoubtedly Japan's leading department in the field of catheter-assisted treatment. Please feel free to consult us if you require catheter-assisted treatment.

Treatment details
Cardiology provides advanced medical care for acute, severe cardiovascular diseases. We accept patients with acute coronary syndromes (acute myocardial infarction and unstable angina) requiring emergency care 24 hours a day, providing emergency coronary artery treatment. For life-threatening arrhythmias, we offer catheter ablation or implantable cardioverter-defibrillators. For patients with severe heart failure and severe ventricular arrhythmias, we implant implantable cardioverter-defibrillators with biventricular pacing. In our outpatient department, we provide a wide range of cardiovascular care, including ischemic heart disease, arrhythmias, heart failure, pericardial myocardial disease, valvular disease, congenital heart disease, carotid artery stenosis, renal artery stenosis, and obliterative arteriosclerosis. We particularly welcome referrals from nearby medical institutions. We provide care based on the request written on the referral letter, providing results as quickly as possible and reporting them to the referring physician. For example, patients with unexplained chest pain are screened using a coronary CT scan (FFR-CT) using dual-source CT and photon-counting CT, both of which are installed at Tokai University Hospital. CT scans provide images similar to those obtained with coronary angiography, and can also provide quantitative evaluation using FFR-CT, making them extremely useful.
In cases where cardiac catheterization is required, cardiac catheterization is performed on an outpatient basis. Because a very thin catheter is used via the radial artery approach, cardiac catheterization, which previously required hospitalization, can now be performed on an outpatient basis. There are still few hospitals in Japan that perform same-day cardiac catheterization, but depending on the case, it can be performed on an outpatient (same-day) basis.
Main target diseases
1. Coronary artery disease - myocardial infarction, angina pectoris
In acute myocardial infarction, the sooner the time from onset to opening the coronary artery is, the lower the mortality rate. In our department, we strive to shorten the time from when a patient arrives at the hospital to when a coronary intervention is performed. Recently, it has been said that shortening the time from onset to intervention is important, so if acute myocardial infarction is suspected, please refer the patient to our department as soon as possible.
Drug therapy is the first treatment for angina pectoris, but if drug therapy does not improve quality of life, coronary intervention is effective. At our department, we use thinner catheters and perform the procedure via the radial artery approach, reducing the burden on patients. Diagnostic catheterization is performed on an outpatient basis at our hospital, eliminating the need for hospitalization. While the use of a device called a rotablator, which cuts into the coronary arteries, is not available everywhere, our department has obtained facility certification. We are also certified as a facility for cutting-edge advanced medical treatments such as lasers and shockwaves.
2. Arrhythmic disorders
We perform catheter ablation, including pulsed field ablation, for a variety of tachyarrhythmias, including atrial fibrillation, which has been increasing in Japan in recent years. We also provide a wide range of arrhythmia treatments, led by arrhythmia specialists, including permanent pacemakers for bradyarrhythmias, implantable cardioverter defibrillators for life-threatening ventricular arrhythmias, biventricular pacemakers (cardiac resynchronization therapy) for refractory heart failure, left bundle branch pacing therapy, and implantable electrocardiograms for early diagnosis of latent atrial fibrillation in patients with unexplained syncope and cerebral infarction of unknown embolic origin. Additionally, for refractory ventricular tachycardia that is difficult to treat with catheter ablation, we offer minimally invasive arrhythmia treatment using external beam radiation (X-rays), making us one of the leading facilities in Japan for this treatment.
3. Peripheral vascular disease
Carotid artery stent placement for carotid artery stenosis is effective in preventing cerebral infarction. As a leader in Japan, our department has provided guidance to specialists across the country. We have ample know-how to safely perform carotid artery stents. We also actively perform catheter treatments for lower limb occlusive arteriosclerosis, particularly comprehensive severe chronic lower limb ischemia (CLTI).
4. Structural heart disease
We actively accept patients who are suspected of having structural heart disease as well as undergoing catheter treatment for valvular disease, and we consider the optimal treatment method in a heart team centered around Cardiology, Cardiovascular Surgery, and Department of Anesthesiology. The main target patients are as follows.
1) Aortic valve disease (aortic valve stenosis (AS), aortic regurgitation (AR))
2) Mitral valve disease (mitral stenosis (MS), mitral regurgitation (MR))
3) Other valvular diseases (pulmonary valve (PS/PR), tricuspid valve (TR))
4) Atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA)
5) Hypertrophic cardiomyopathy (HCM)
6) After cardiac surgery
7) Chronic thromboembolic pulmonary hypertension (CTEPH)
8) Patients with atrial fibrillation who are at high risk of bleeding/who cannot undergo anticoagulation
We perform procedures such as transcatheter aortic valve implantation (TAVI), percutaneous aortic balloon angioplasty (BAV), transcatheter mitral valvuloplasty (MitraClip), and mitral commissurotomy (PTMC) for the above valvular diseases. As our hospital is a specialized transcatheter aortic valve replacement facility certified by the Council of Societies Related to Transcatheter Valvular Disease Treatment, we also perform TAVI for dialysis cases and TAVI (valve-in-valve) for valvular insufficiency after surgical aortic valve replacement. Our hospital also provides safe treatment using alternative approaches for cases where TAVI via the standard femoral artery approach is not possible.
We have also performed transcatheter atrial septal defect closure for atrial septal defect (ASD), transcatheter foramen ovale closure for patent foramen ovale (PFO) that has developed paradoxical cerebral embolism, and transcatheter left atrial appendage closure (LAAO, Watchman) for patients with atrial fibrillation who are at high risk of bleeding or who are unable to undergo anticoagulation, with good results. Pulmonary artery angioplasty (BPA) for chronic pulmonary thromboembolic pulmonary hypertension (CTEPH) and percutaneous transluminal septal ablation (PTSMA) for hypertrophic obstructive cardiomyopathy are also extremely effective in improving symptoms.
5. Heart failure and cardiogenic shock
For severe cardiogenic shock, in addition to conventional intra-aortic balloon pumping (IABP) and extracorporeal cardiopulmonary bypass (ECMO), we have introduced Impella, a left ventricular assist pump, and can handle even the most severe cases.
As the number of cases of chronic heart failure continues to increase, we have established a multidisciplinary heart failure team to examine each case and are actively incorporating outpatient cardiac rehabilitation and hospitalization for heart failure education in an effort to improve prognosis.
Main medical achievements
We offer cutting-edge treatments, including coronary artery rotablization, laser angioplasty, and carotid artery stents. Diagnostic coronary catheterization is also available on an outpatient basis. We have consistently achieved results with implantable treatments for arrhythmias and implantable Holter monitors. PCI for multivessel disease is performed all at once, so although the number of elective PCI cases appears low, patients are pleased with the service.
