Your doctor has recommended that you have cardiac surgery. But what does that actually mean?
Your heart is located in the center of your chest. It is surrounded by your rib cage and protected by your breastbone. Your heart's job is to keep blood continually circulating throughout your body.
The vessels that supply the body with oxygen-rich blood are called arteries.
The vessels that return blood to the heart are called veins.
Like any other muscle in the body, the heart depends on a steady supply of oxygen rich blood. The arteries that carry this blood supply to the heart muscle are called coronary arteries.
Sometimes, these blood vessels can narrow or become blocked by deposits of fat, cholesterol and other substances collectively known as plaque.
Over time, plaque deposits can narrow the vessels so much that normal blood flow is restricted. In some cases, the coronary artery becomes so narrow that the heart muscle itself is in danger.
Coronary bypass surgery attempts to correct this serious problem. In order to restore normal blood flow, the surgeon removes a portion of a blood vessel from the patient's leg or chest, most probably the left internal mammary artery and the saphenous vein.
Your doctor uses one or both of these vessels to bypass the old, diseased coronary artery and to build a new pathway for blood to reach the heart muscle. These transplanted vessels are called grafts and depending on your condition, your doctor may need to perform more than one coronary artery bypass graft.
Of course, operating on the heart is a complex and delicate process and in the case of bypass surgery, your doctor will most likely need to stop your heart before installing the graft.
During the time that your heart is not beating, a special machine, called a heart-lung machine, will take over the job of circulating and oxygenating your blood.
By using this machine, your doctor is able to repair the heart without interfering with the blood flow to the rest of the body.

Before we talk about treatment, let's start with a discussion about the human body and about your medical condition.
Your doctor has recommended that you have surgery to treat an abdominal aortic aneurysm. But what does that actually mean?
The aorta is the main blood vessel that carries oxygen-rich blood from your heart to the organs in your body.
An aneurysm is a bulge or swelling in a blood vessel.
This type of bulge occurs when a blood clot ... or blood clots develop in the aorta, causing to expand.
In your case, your doctor has determined that a portion of the aorta passing through your abdomen - the area between your legs and your chest - has developed a blood clot. In most cases these clots are caused by fatty deposits that build up inside the arteries.
Aneurysms are dangerous because the blood clot weakens the blood vessel and can cause it to burst.
The surgery your doctor has recommended will remove the blood clot ...
... and reinforce the weakened wall of the aorta.
So make sure that you ask your doctor to carefully explain the reasons behind this recommendation.

Your doctor has recommended that you receive a permanent pacemaker implanted in your body. But what does that actually mean?
The heart is located in the center of the chest, enclosed by the breast bone and rib cage. By contracting in a rhythmic way, it causes the blood in your body to circulate.
A normally functioning heart beats at a rate of between 60 and 100 contractions per minute.
These contractions are triggered by a small piece of heart tissue called the SA node. The SA node generates a small electrical signal that is transmitted by nerves to the surrounding muscle. These electrical impulses are what cause the heart muscle to contract.
In some people, the SA node fails to cause the heart to contract with its normal rhythm, causing an abnormal heartbeat or arrhythmia. The most common form of arrhythmia, for which pacemaker surgery is often recommended, is bradyarrythymia - or slow heart rate.
There are a number of reasons why you may have developed an arrhythmia, but in most cases the problem is caused by a disruption in the SA node or in the system of nerves that conducts electrical signals to the heart muscle.
A pacemaker is a device that is designed to provide an electrical signal to the heart muscle and to help it maintain a proper rhythm. There are several types of pacemakers and the particular model selected for you will be based on your specific condition. But all pacemakers share a common design.
Your pacemaker will consist of two major pieces . . . a small metal box that contains a battery and other electronic components and an insulated wire, called a lead, which will carry the electrical impulses from the pacemaker to the heart.
Your pacemaker will be permanently implanted in your chest and, depending on your condition, either one or two leads will be attached to the heart muscle.

Your doctor has recommended that you undergo a cardiac catheterization. But what does that actually mean?
The heart is located in the center of the chest. It's job is to keep blood continually circulating throughout the body.
The blood vessels that carry oxygen-rich blood away from the heart are called arteries.
The largest and most important of these is the aorta.
The vessels that bring blood back into the heart are called veins.
Sometimes, these blood vessels can grow narrower or become blocked in such a way that normal blood flow is restricted. In simple terms, a cardiac catheterization is a diagnostic procedure used when your doctor believes that blood is not flowing normally in and or around your heart.
In simple terms, a cardiac catheterization is a diagnostic procedure used when your doctor believes that blood is not flowing normally in and or around your heart.
During a cardiac catheterization, a heart specialist will insert a thin tube into an artery in the arm or leg and gently guide it towards the problem area in the heart.
Once the tube is in place, a special dye is injected and a series of x-rays are taken.
These x-rays allow your doctor to see exactly how blood is flowing in your heart.

Your doctor has recommended that you undergo a balloon angioplasty. But what does that actually mean?
The heart is located in the center of the chest. It's job is to keep blood continually circulating throughout the body.
The blood vessels that supply the body with oxygen-rich blood are called arteries.
The arteries that supplies blood to the heart muscle itself are called coronary arteries.
Sometimes, these blood vessels can narrow or become blocked by plaque deposits, restricting normal blood flow.
In simple terms, a balloon angioplasty is a procedure used to increase the amount of blood flowing through the coronary artery.
During a balloon angioplasty, a heart specialist will insert a thin tube into an artery in your arm or leg and gently guide it towards the problem area in your heart.
Once the tube is in place, a small balloon is briefly inflated in order to widen the narrowed artery.
During and after the procedure, your doctor will take x-rays in order to monitor your progress.
