Adult Heart Disease – Coronary Artery

Coronary Artery Disease and Surgery

Main coronary artery diseases (CAD) handled by our department:
Coronary arteriosclerosis, myocardial infarction (heart attack), angina, ischemic cardiomyopathy
The heart plays he important role of sending blood to the body, but blood is also necessary for the heart itself.
A blood vessel that sends blood to the heart is called a coronary artery (a red blood vessel in the figure below). If the coronary arteries are narrowed (stenosis) or clogged, oxygen and nutrients cannot reach the heart muscle (myocardium), and normal functioning is not be possible.
Symptoms may include difficulty breathing, sudden fatigue, reduced urine volume, and chest pain. These symptoms may indicate life-threatening heart-failure. If a coronary artery disease is suspected, please contact a medical institution immediately.
Treatment include surgery and medicine, and the policy is adapted according to the condition of the patient to place as small a burden on the body as possible.

Pharmaceutical treatments Treatments to restore blood flow
Medicine to recover from ischemic condition
Percutaneous coronary intervention (PCI)
(improve blood flow with a catheter*)
Blood-thinning medicine
Coronary artery bypass
(surgery making a new path for the coronary artery)
  • * catheter: a tube used for medical use. Here it is inserted into the coronary artery to improve blood flow.
    Besides the above, cardiac rehabilitation, in combination with an improvement in lifestyle, is also effective.
  • N.B. Percutaneous coronary intervention (PCI) is a treatment where the physiological burden of surgery is smaller than that of coronary artery bypass surgery, but may not be sufficient for patients with clogging in a wide range of coronary arteries, or clogging in thin coronary arteries.

Coronary Artery Bypass Grafting (CABG)

  • The figure on the left shows as the coronary artery narrows or becomes obstructed, sufficient blood does not flow to the end of the blood vessel. This is ischemia.
  • The figure on the right shows how blood flow improves after creating a new path for blood (bypass) using the patient's own blood vessels.

A doctor judges the location and method of creating a bypass, according to the conditions of the disease and blood vessel.
The bypass blood vessel is collected from the thigh or arm of the patient.

In addition to ordinary coronary artery bypass surgery, our hospital is working to refine surgery bypass surgery with no need for a heart-lung machine (off-pump coronary artery bypass surgery, OPCAB), and in some cases small incision coronary artery bypass surgery (MICS-CABG) which has no need for sternotomy. These techniques aim to reduce the physiological burden of surgery to increase safety and ease recovery.
