AboutAbout the lab
Treating the heart and great vessels by surgery
The lab works on surgical methods for treating diseases of the heart and great vessels.
Its targets are coronary artery disease, valvular heart disease, arrhythmia, aortic disease, severe heart failure, congenital heart disease, and chronic thromboembolic pulmonary hypertension.
It also handles ventricular assist devices and heart transplantation for severe heart failure, covering a wide range of cardiovascular surgery.
It also participates in clinical research, such as a nationwide survey on how drugs are used to suppress acute rejection after transplantation.
Key terms
- Coronary arteries
- The blood vessels that supply blood to the heart muscle itself. A blockage causes angina or myocardial infarction
- Valve repair
- Surgery that repairs and preserves a damaged heart valve instead of replacing it with an artificial valve
- Aortic aneurysm
- A condition in which part of the aorta bulges like a balloon. It carries a risk of rupture as it grows larger
ResearchResearch themes
The lab treats diseases of the heart and great vessels surgically, from coronary artery disease to valvular disease, arrhythmia, aortic disease, and severe heart failure. For valve disease it performs valve repair whenever possible, and it continues multicenter studies on surgery for atrial fibrillation.
*Illustrative imageCoronary Artery Disease
When the coronary arteries narrow or become blocked due to arteriosclerosis, angina or myocardial infarction results. The lab's first choice is off-pump, beating-heart coronary artery bypass grafting, aiming for durable bypasses that use arteries wherever possible.
*Illustrative imageValvular Heart Disease
A disease in which one of the heart's four valves narrows or leaks. The lab performs valve repair, which gives a better quality of life after surgery, whenever possible, and has made repair the standard operation even for complex mitral valve cases considered difficult.
*Illustrative imageArrhythmia
For patients with atrial fibrillation undergoing open-heart surgery, the lab performs the Maze procedure, creating electrical isolation lines in the atria. Since 2011 it has also introduced ablation of the autonomic ganglionated plexi in the heart, and continues research at multiple centers.
*Illustrative imageAortic Disease
An aortic aneurysm, in which part of the aorta bulges, carries a risk of rupture as it grows larger. The lab handles treatment including thoracic and abdominal endovascular stent grafting.
