Efforts in Cardiovascular Surgery

For each disease, the heart team (cardiovascular surgery/cardiovascular internal medicine) selects the most suitable treatment method and provides medical care.We also actively pursue minimally invasive treatments.

Coronary artery disease

Angina pectoris and myocardial infarction are caused by obstruction of blood flow due to stenosis or blockage of blood vessels (coronary arteries) that supply blood to the heart.Coronary Artery Bypass Grafting (CABG) is performed as a surgical treatment to improve blood flow.At our hospital, we actively perform off-pump CABG (OPCAB) without a heart-lung machine to avoid complications from surgery using a heart-lung machine.
Since the heart does not stop, it is a less invasive surgery with less stress on the heart.

Valvular disease

Valvular disease is a condition in which the valves in the heart have problems and cannot function normally.
At our hospital, we perform aortic valve replacement with a catheter (Transcatheter Aortic Valve Implantation; TAVI) for aortic valve stenosis.For mitral regurgitation, we also perform mitral valvuloplasty without using an artificial valve, leaving the patient's own valve, which has the advantage of avoiding complications that occur with valve replacement.
We also introduce minimally invasive cardiac surgery (Minimally Invasive Cardiac Surgery; MICS).

Aortic disease

Due to causes such as arteriosclerosis, the aorta becomes aneurysm (abdominal aortic aneurysm, thoracic aortic aneurysm).
Since an enlarged aneurysm increases the risk of rupture, surgical treatment is required to prevent rupture.
Treatment methods include artificial blood vessel replacement and minimally invasive thoracic/abdominal stent graft treatment (Thoracic Endovasculal Aortic Repair; TEVAR/EVAR).In addition, we are striving for minimal invasiveness by using artificial blood vessel-based bypass surgery, hybrid treatment with TEVAR/EVAR, and fenestration-type stent grafts (Najuta®).

peripheral arterial disease

Stenosis or occlusion of the arteries of the lower extremities may cause pain in the calves when walking that is relieved when resting (intermittent claudication), pain at rest, and toe ulcers.Aggressive revascularization (endovascular treatment or bypass surgery) is required when resting pain or ulcers are observed.We offer optimal treatment methods such as distal bypass to the lower leg and hybrid treatment (simultaneous endovascular treatment and surgical treatment).

Approach No. 53 (issued in October 2014) "Doctor's Relay Lecture" "Do you know PAD?"

Varicose veins of the lower extremities

It is a disease that makes the veins of the legs look like bumps and bumps.
As treatments, we perform minimally invasive EndoVenous Laser Ablation (EVLA) and intravenous endovascular adhesive treatment (VenaSeal®) for one night and two days.

A word to patients

About outpatient consultation

The outpatient clinic for new patients is on Tuesday and Friday mornings.
If possible, please bring a letter of introduction from your family doctor or a nearby medical institution.Reservations are required for other outpatients.
Mondays, Wednesdays and Thursdays are surgery days.For emergency cases, please contact the emergency reception (hospital representative phone number).
The ward doctor or the emergency doctor will respond.
We also provide outpatient services for consultation on stent graft treatment for aortic aneurysms.
Since 2009, the Department of Cardiology has been in charge of outpatient services for pacemakers.
Second opinions are available at any time and are by appointment only.Please feel free to contact us.
