-
- QUESTION: I am a bit puzzled about heart surgery, as I have heard it called
- by many names. Can you please explain the difference between "open heart
- surgery" and "by-pass" surgery? I enjoy your column very much and hope that I
- am soon find the answer to my question there. Thank you.

- ANSWER: Let's see if I can put things into perspective for you. Open heart
- surgery implies opening the chest and then operating on the heart. In many
- cases the heart is temporarily stopped, and the circulation of blood
- throughout the body is assured by a heart-lung machine which is used to pump
- the blood. "By-pass" surgery is thus one of the many types of open heart
- surgery performed today. It is used to overcome the blockage or partial
- blockage that can restrict the flow through the arteries that bring blood to
- the heart muscles themselves. The blockages are formed by fatty deposits on
- the insides of the artery (atherosclerosis). This is the condition that leads
- to angina or heart attacks. A graft is used, made either from artificial
- material or from a vein taken from the patient. The saphenous vein of the
- leg is the vein usually used for this purpose, The graft is place to carry the
- blood around the area that is blocked, to restore the normal blood flow. From
- 3 to 9 by-passes can be placed during one operation with 4 or 5 being most
- common.
- In other types of heart surgery the heart itself is opened, to repair or
- replace damaged valves on the inside of the heart, to repair holes in the
- walls that separate the different chambers of the heart (septal defects) that
- may be the result of congenital abnormalities, or in some cases to remove
- tumors from the inside of the heart. Once the repairs have been accomplished,
- the heart is restarted and the heart-lung machine is turned off.
- Open heart surgery is no longer uncommon, but improvements in techniques
- have brought it to a remarkable degree of perfection. Open heart surgery is
- now performed in hospital centers across the United States.
