The Heart Valves
There are four valves that control the flow of blood through the four chambers of the heart. They are like one-way doors that keep the blood moving in one direction and prevent it from backing up into the chamber from which it came. When the heart beats, the valves close to keep the blood from flowing backward.
What causes a heart valve problem?
The four valves in the heart ensure that the blood flows forward as your heart contracts and relaxes. The valves are made of thin but extremely strong flaps of tissue that open and close as your heart beats they are called leaflets or cusps. A human heart beats more than 100,000 times a day. The valves must flex, stretch and hold back pressure hundreds of millions of times in an average lifetime. As we age the valves can weaken and harden.
The mitral and aortic valves on the left side of the heart are most commonly affected by aging because pressures are higher on the left side. The right heart valves can be damaged by infection or by back-pressure from the lungs because of lung disease.
When disease causes the valves to harden and weaken, they will not open properly and the blood flow is blocked or flows in the wrong direction.
Understanding Heart Valve Surgery
Heart Valve repair and heart valve replacement operations have become very common. These operations are done to improve the health, quality and longevity of life for those who have heart valve disease.
There are several things that can cause problems with your heart valves. A heart valve may have a mild defect at birth that will slightly weaken the valve and affect blood flow. Over time, this leads to failure of the valve. Diseases like rheumatic fever or bacterial infections may scar or destroy the valve. Aging and normal wear and tear of tissues can weaken or harden heart valves. Your heart valves have been opening and closing with each heart beat for your entire life. Some wear and tear is to be expected.
What is heart valve surgery?
Heart valves may either be repaired or replaced, depending on the degree of damage. Sometimes the surgeon can restore the valve to function normally by remodeling the tissue-removing stretched tissue or sewing the edges. Prosthetic or artificial rings are used to narrow a dilated valve and to reinforce valve repairs. One advantage of a heart valve repair operation is that a person’s own valve tissues are used.
Heart valves that are seriously deformed or degenerated cannot be repaired. The old valve is removed and replaced with a new valve mechanism. A new valve is attached by sewing it to a rim of tissue kept from the original valve. There are different types of valve mechanisms, but they fall into two categories-tissue valves and mechanical valves. The cardiac surgeon will extensively review the risks, benefits and appropriateness of these choices with patients who need this type of surgery.
How do I prepare for heart valve surgery?
Feeling anxious is very natural when considering any type of operation. You can reduce your anxiety by resting, eating well, limiting exercise, and talking to the health care professionals who are handling your case. Having the procedure explained to you, voicing your concerns, and getting your questions answered will help put you at ease. Being well informed will help you feel more relaxed as the procedure draws near. We have printed literature and information regarding these procedures that explain them in detail. It is best to get specific information about your own case from your doctor, who will review and discuss your specific clinical situation with you.
What are the risks?
As in all major surgery, there are risks. Heart valve surgery has an excellent success rate. There is a small risk of:
- Heart attack
- Kidney failure
After careful review of your medical history and a physical exam, your surgeon will identify your risks.
What happens after surgery?
After you are discharged from the hospital, you will have regular visits with your surgeon and cardiologist.
Eating nutritious meals is very important to your healing. Limiting how much salt you eat is often advised after heart valve surgery. You are strongly urged to give up tobacco products if you are a consumer.
Follow gradual exercise program to help you have a quicker recovery.
You will discuss with your surgeon when you can resume driving, return to work, and with what limitations. Your doctor will also discuss your medications. Even over-the-counter medications will need your physician’s approval.
Your successful recovery depends on how well you follow medical advice, exercise, and follow healthy living suggestions.
