れるようになってきている。2. Description of the Related Art Conventionally, surgery for patients with myocardial infarction or angina has mainly been performed by so-called aortic / coronary artery bypass surgery in which a foot vein is collected and connected to a heart vessel. It turned out that the bypass used clogged naturally and stopped functioning about 5 years after the operation. Therefore, bypass surgery has been performed in which arteries are collected from various parts instead of veins and transplanted into blood vessels of the heart.
