Discover yourself and find your place here at MMAH.
3 EndoVascular Treatment
At our hospital, using the techniques we inherited from PCI (Percutaneous Coronary Intervention) we carry out about 250-300 peripheral vascular intervention (EVT: Endovascular Treatment) procedures every year, covering 70% of cases within Miyazaki.
With new devices and improved outcome, we have seen continuously increasing demand for EVT, not only for simple case, but highly demanding complex cases as well. in the treatment and successful results of EVT, particularly in the lower limb arteries.
Even if you have never taken part in an EVT procedure before, you will be given lots of opportunities to learn, from the fundamentals of endovascular disease to all the treatment options, to how to conduct an EVT procedure to how to be an operator yourself, all here at MMAH with the help of specialists
At MMAH, you can learn not only PCI techniques, but also EVT techniques which will bring positive impact on your PCI skills, setting you with breadth of knowledges and skillsets.
4 TREATMENT of ARRHYTHMIAS: Heart Rhythm Abnormalities
Our Commitment to Miyazaki Citizens
At our facility we annually perform 490 ablation procedures (2019). We are currently accepting patients who are recommended for ablation treatment by their primary care doctor. At MMAH ablation operations are scheduled from Monday to Friday, except for Tuesday when we have outpatient examination scheduled.
Our cardiovascular specialists at MMAH can treat most atrial fibrillation cases by a noninvasive catheter ablation, rather than a surgical approach. There are also other treatments available for patients who have a wide range of arrhythmia types, including atrial tachycardia, ventricular arrhythmia, paroxysmal supraventricular tachycardia, and ventricular tachycardia.
Through these experiences our arrhythmia team has successfully treated many complex procedures, and have actively been involving young cardiology physicians in the ablation procedure. This training allows them to investigate arrhythmia and learn therapy procedures in depth, leading to enthusiasm and understanding for their future career prospects.
It is often said that heart institutes to use only one of two possible cardiac mapping devices: CARTO or ENSITE, for ablation procedure. At MMAH, we have both systems on site. Since two systems have both strengths and weaknesses, we make use of both systems, to perform cutting edge treatment, while also to provide learning experience of both 3D cardiac mapping devices for young physicians.
Recently, we have also started using RHYTHMIA, which is the very latest treatment system. Options for arrhythmia treatment will continue to expand in the future, making it possible to provide even higher quality medical care.
We have a strong focus on pioneering medical devices for the heart’s electrical system for our patients. New physicians can anticipate training in implantation of pacemakers, ICD, and CRTD, under the guidance of board certified members of the Japanese Heart Rhythm Society, and Fellows of Japanese Circulation Society (FJCS).
We have highly motivated and active team, and are always open to young physicians seeking advice. Join us at MMAH, and let’s raise the bar of ablation therapy in Miyazaki.
5 STRUCTURAL HEART DISEASE
For the next level of intravascular interventions for coronary arteries or peripheral vessels at MMAH, noninvasive catheter treatment for structural heart disease is centered in the hybrid operation room in recent years. We mainly treat Valvular disease, a structural heart disease (SHD) intervention that is spreading rapidly in Japan. In this era of new technology, a cardiac operation called TAVI is becoming our major mission for us to improve the QOL of elderly cardiac patients with severe valve condition.
Our SHD intervention therapy includes TAVI (Transcatheter Aortic Valve Implantation) approved in October 2013, “MitraClip” for TMVR (Transcatheter Mitral Valve Repair) approved in April 2018, and “WATCHMAN” (left atrial appendage closure system) to prevent cardiogenic embolism, approved in September 2019.
In October 2015, we installed a hybrid operation room (HOR) in cooperation with PHILIPS Co. Since then, MMAH has introduced TAVI from April 2016, MitraClip from December 2018, and WATCHMAN from December 2019. As of May 2020, we have demonstrated excellent outcome, with zero peri-operative mortality.
At our brand new hospital relocation in August 2020, a hybrid operating room equipped with the latest X-ray angiography system (Azurion7 C20 with FlexArm, Philips) is set in operation, and an echo image is obtained on the X-ray fluoroscopic image. This latest system provides the cutting-edge technologies like “real-time fusion imaging”, enabling us to give the patients the latest treatment options.
In SHD intervention, the existence of a Heart Team including imaging specialists, cardiovascular surgeons, anesthesiologists, and medical staff is extremely important. Cross-functional discussion within the heart team is necessary for preoperative evaluation and case selection. Daily joint conferences with cardiologists and cardiovascular surgeons with different expertise are also critical. This joint conferences provides the team with platform to openly discuss each patient care strategy, and decide on the best therapy options available. To seek best outcome for our patients, we continue to hold conferences, such as weekly echocardiographic case reviews and preoperative case conferences within the Heart Team, to learn and educate ourselves.
Our dedication to enhancing the treatment of structural heart disease is our commitment to the citizens of Miyazaki.
6 Our Determinations in Heart Failure Community
According to a 2018 survey report by the Statistics Bureau of the Ministry of Internal Affairs and Communications, Japan has the highest percentage of the total population of the elderly in the world (28.1%). In fact, the number of patients with heart failure due to the aging factor is ever increasing. Correspondingly, this fact can suggest a “pandemic of heart failure—leading to a global pandemic" in the not far future.
This potential pandemic calls for not only treatment of heart failure in general, but also comprehensive intervention by multi-disciplinary teams at each medical institution. Heart failure prevention, recurrence prevention, and rehabilitation are three important elements for the treatment of heart failure patients.
In Miyazaki, we strive to establish a comprehensive collaboration care system for heart failure patients including three institutions: first acute care medical institutions like MMAH, secondly recovery-stage care medical institutions that perform rehabilitation during convalescence, and lastly the importance of home-doctors who can visit anytime should be more widely acknowledged.
Our mission is to build a collaborative system for heart failure medical treatment that matches the regional characteristics of Miyazaki.
In particular, heart failure in the elderly has many peculiar problems not limited only to the heart, but also of frailness (physical or mental infirmity due to aging), sarcopenia (natural loss of muscle tissue in the aging process), dementia, as well as economic and social background.
It is necessary to build a community team that comprehensively cares for elderly heart failure patients in a regional manner by strengthening cooperation not only with medical institutions but also with geriatric health facilities and home nursing care. We have created and are following the heart failure handbook for Miyazaki, stating our own clinical path for regional cooperation for heart failure, and utilize it for the development of advanced medical care for heart failure.
Aiming at heart failure treatment and regional medical cooperation that is appropriate for Miyazaki Prefecture, we hold seminars and research meetings about twice a month with multiple experts from both inside and outside the hospital.
Catheter therapy for coronary artery disease and Valvular disease is in the limelight treating for heart disease. However, the diagnosis of heart failure is of paramount importance because cardiovascular disease can result in heart failure. Heart failure collaboration is the field of the future, and we hope you join us at MMAH, where you will be exposed to very unique and rewarding experiences through multi-professional cooperation and regional coordination.

Target cardiac disease and its numbers, 2019
In 2019, 761 cardiac patients underwent rehabilitation for recovery. The graph shows the breakdown of 590 cases from cardiology and 171 cases from cardiovascular surgery. Most cases were indicated with heart failure or acute myocardial infarction.
The need for cardiac rehabilitation has been increasing yearly. We have constantly been conducting more than 700 cases annually in recent years.
Our medical rehabilitation plans are based on a cardiac physician’s prescription, especially for patients with heart failure or myocardial infarction. In the acute phase the physical therapist in charge will provide one-on-one instruction at the bedside. While confirming the condition with the cardiac physician, exercise will be increased, and finally proceed to the next stage such as group rehabilitation or CPX. If problems arise, consultations are held in the cardiac rehabilitation conference to enable patients to return home as soon as possible.
Cardiopulmonary exercise testing; CPX
This is a test that simultaneously measures cardiopulmonary function, skeletal muscle function, etc. during exercise. A gas analyzer measures how much oxygen is being inhaled and how much carbon dioxide is being exhaled in one minute, and the anaerobic threshold (AT), which is an index of cardiopulmonary function, is calculated. This enables heart disease patients to enjoy efficient exercise in a safe range of intensity. Additionally, it can be a tool for determining the possibility of heart disease, such as coronary artery disease, and a measurement for the severity of the disease using an electrocardiogram. Since it is possible to evaluate the degree of heart failure by measuring the cardiac reserve, it is also used as a stress test for cardiac rehabilitation.
At MMAH, the cardiac physician attends the CPX and conducts examinations with the physiotherapist in charge, to make it possible to have a more effective CPX
Cardiac Rehabilitation Conference
A weekly meeting is held on Tuesday mornings to check the current status of rehabilitation and discuss issues regarding ongoing cases. Professionals from various fields, including physiotherapists, cardiologists, nurses, medical technical staff, social workers, and medical clerical workers participate and comprehensive care and medical strategies from various perspectives are planned for each case. The physical therapists share information on daily rehabilitation and CPX, and concentrate on the physical (and often psychiatric) problems of each case. Nurses and social workers will focus on the patients’ social background. This leads to the construction of a concrete treatment plan.
For your career
Cardiac rehabilitation, along with pharmaceutical therapy, cardiac catheterization, and cardiovascular surgery, are very important aspects of treatment for patients with cardiac disease. It is important to provide comprehensive care for patients with heart disease, because it is often necessary to take a social approach as well as treating the physical and psychiatric concerns. At MMAH an environment is in place where professionals with different expertise can share information and exchange their opinions. The staffs of the rehabilitation division are strongly committed to helping shape advanced cardiac rehabilitation therapy for Miyazaki citizens. We welcome you to join us in this task!
8 Our cardiovascular intensive care unit
At MMAH, we have 12 CCU (Cardiovascular Intensive Care Unit) beds. In 2019, the CCU team took care of 178 out of the 233 emergent patients with acute coronary syndrome. The number of emergent cardiac patients who are transferred to, and accepted at our hospital is one of the highest in Japan. The Open CCU allows each attending physician and cardiac specialist to be involved in the treatment, and to become well versed in acute hemodynamic management and cardiovascular/respiratory assistance devices. In addition, we have a unified team treatment system based on the daily rounds and conferences.
