- QUESTION: Following a recent severe heart attack, my father developed an
- aneurysm in his heart. We have discussed the situation with his doctor, who
- because of a gradual decline in Dad's condition is recommending surgery. We
- have tried to study up on this condition, but are becoming confused as we read
- of the same condition in the brain and aorta. Is there any chance you can
- sort this out for our family?

- ANSWER: To start the sorting out process, let's define an aneurysm for you.
- The word comes from the Greek word that means "a widening," and in fact an
- aneurysm is a widening or sac formation in a weakened section of the wall of
- any artery, vein or the heart. Aneurysms occur most frequently in the portion
- of the aorta (the largest artery in the body) the passes through the abdomen.
- They are found less frequently in the heart, the major blood vessels of the
- chest, and the brain. In your father's case, a portion of the muscle of the
- heart died when he had his heart attack. The artery leading to this section
- of the heart wall became blocked, probably by a blood clot, and the blood
- flow to the heart tissue stopped. Without the oxygen and nutrients carried by
- the blood, the heart tissue could not survive. During the healing process,
- the dead heart muscle was replaced by a thin scar, without the necessary
- strength to contain the pressure that develops each time the heart contracts.
- It is probably this area that is now bulging outward with each beat, forming a
- sac or aneurysm. This, in turn, reduces the ability of the remaining heart
- muscle to perform the vital function of pumping the blood to the body. While
- the heart works harder to compensate, it uses more oxygen, and if the supplies
- are inadequate, angina may develop, or heart failure may rear its ugly head.
- When the aneurysm is removed surgically, the efficiency of the heart is
- improved, angina disappears, and your father's general condition improves.
- Frequently, a cardiac artery bypass procedure is performed at the same time as
- the aneurysm is removed, to help improve the circulation to the heart. In
- your reading, do not be confused by reference to arterial aneurysms, where the
- walls of the vessels are weakened by progressive atherosclerosis, or brain (or
- berry) aneurysms which are the result of a congenital condition. The
- operation sounds well advised in your father's case, and should be performed
- as soon as possible, before he worsens further.
