Aortic Valve Replacement
WHAT YOU NEED TO KNOW:
Aortic valve replacement is surgery to put a new aortic valve in your heart. Your aortic valve separates the lower section of your heart from your aorta. The aorta is the large blood vessel that carries blood from your heart to your body. Your aortic valve opens and closes to let blood flow from your heart. When your aortic valve does not open or close as it should, the amount of blood that your heart can pump to your body decreases.
WHILE YOU ARE HERE:
Before your surgery:
- Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
- You will need blood tests, and you may need any of the following:
- Transesophageal echocardiogram:
- A transesophageal echocardiogram (TEE) is a type of ultrasound that shows pictures of the size and shape of your heart. It also looks at how your heart moves when it is beating. These pictures are seen on a TV-like screen. You may need a TEE if your heart does not show up very well in a regular echocardiogram. You may also need a TEE to check for certain problems such as blood clots or infection inside the heart.
- You will be given medicine to relax you during a TEE. Caregivers put a tube in your mouth that is moved down into your esophagus (food pipe). The tube has a small ultrasound sensor on the end. Since your esophagus is right next to your heart, your caregiver can see your heart clearly.
- Vital signs: Caregivers will check your blood pressure, heart rate, breathing rate, and temperature. They will also ask about your pain. These vital signs give caregivers information about your current health.
- A pulse oximeter is a device that measures the amount of oxygen in your blood. A cord with a clip or sticky strip is placed on your finger, ear, or toe. The other end of the cord is hooked to a machine.
- An IV is a small tube placed in your vein that is used to give you medicine or liquids.
- General anesthesia will keep you asleep and free from pain during surgery. Anesthesia may be given through your IV. You may instead breathe it in through a mask or a tube placed down your throat. The tube may cause you to have a sore throat when you wake up.
- Heart monitor: This is also called an ECG or EKG. Sticky pads placed on your skin record your heart's electrical activity.
- Arterial line: An arterial line is a tube that is placed into an artery (blood vessel), usually in the wrist or groin. The groin is the area where your abdomen meets your upper leg. An arterial line may be used for measuring your blood pressure or for taking blood.
- Transesophageal echocardiogram:
During your surgery:
Your caregivers make 1 or more incisions in your chest. Your heart is connected to a heart-lung bypass machine. The machine does the work of your heart and lungs while caregivers work on your valve. Your old aortic valve is removed and replaced with a tissue valve or mechanical valve. Caregivers may put wires your chest that stay there in for a short time after surgery. The wires can be used to improve your heartbeat. The bypass machine is removed, and your own heart and lungs start working again. The incision in your chest is closed with wire and stitches.
You are taken to the recovery room or an intensive care unit (ICU). Caregivers will watch you very closely. A bandage is used to cover your stitches or staples. This bandage keeps the area clean and dry to help prevent infection. A caregiver may remove the bandage shortly after surgery to check the incision. Do not get out of bed until your caregiver says it is OK. Your family may be allowed to visit you in the ICU for a short visit several times a day.
Oxygen and a ventilator:
You may need extra oxygen when waking up and for a day or two after surgery. Caregivers may leave an endotracheal tube (ET tube) in your throat. Oxygen can be given through the ET tube by a breathing machine called a ventilator. After the ET tube is taken out, you may still need oxygen. The oxygen may be given through a plastic mask over your mouth and nose. Oxygen may also be given through nasal prongs (short, thin tubes in your nose).
Pulmonary artery catheter:
This is a balloon-tipped catheter (thin tube) inserted through a vein in your neck or groin. The pulmonary artery (PA) catheter goes into the right side of your heart and continues to your pulmonary artery. The balloon is inflated to wedge the catheter in place. The PA catheter has a device in it that measures the pressure in your heart and lungs. The catheter is attached to a monitor that shows the pressure measurements. The measurements can also show caregivers how your heart responds to certain heart medicines.
A chest tube is used to remove air, blood, or fluid from around your lungs or heart. Removing fluid lets your lungs fill up with air when you breathe, and helps your heart beat normally. The chest tube is attached to a container to collect the blood or fluid. Call a caregiver right away if the tube comes apart from the container. Let the caregiver know if the tubing gets bent, twisted, or the tape comes loose. You may need more than one chest tube.
You may need a blood transfusion for certain medical conditions. You may also need a transfusion if you lose a large amount of blood during surgery. You may ask a family member or friend with the same blood type to donate blood for you. This is called directed blood donation. Many people are worried about getting AIDS, hepatitis, or West Nile Virus from a blood transfusion. The risk of this happening is rare. Blood banks test all donated blood for AIDS, hepatitis, and West Nile Virus. If you refuse a blood transfusion, your condition may get worse, and you may die.
This is also called neuro signs, neuro checks, or neuro status. A neurologic exam can show caregivers how well your brain works after an injury or illness. Caregivers will check how your pupils (black dots in the center of each eye) react to light. They may check your memory and how easily you wake up. Your hand grasp and balance may also be tested.
This exercise should be done once an hour to keep you from getting a lung infection. Deep breathing opens the tubes going to your lungs. Slowly take a deep breath and hold the breath as long as you can. Then let out your breath. Take 10 deep breaths in a row every hour while awake. You may be asked to use an incentive spirometer to help you with this. Put the plastic piece into your mouth and slowly take a breath as deep and as long as you can. Hold your breath as long as you can. Then, let out your breath.
Exercise is important after valve replacement surgery. Exercise helps you recover from surgery and may help prevent other medical problems. It can also help prevent depression that often occurs after heart surgery. When you begin to exercise, you will feel tired at first, but over time you will be able to do more. Caregivers will help you begin to exercise. Your caregivers may want you to continue in an exercise program after you leave the hospital. Ask your caregivers to help you make an exercise plan for when you return home.
Intake and output:
Caregivers will keep track of the amount of liquid you are getting. They also may need to know how much you are urinating. Ask how much liquid you should drink each day. Ask caregivers if they need to measure or collect your urine.
You will be able to drink liquids and eat certain foods
once your stomach function returns after surgery. You may be given ice chips at first. Then you will get liquids such as water, broth, juice, and clear soft drinks. If your stomach does not become upset, you may then be given soft foods, such as ice cream and applesauce. Once you can eat soft foods easily, you may slowly begin to eat solid foods.
A Foley catheter
is a tube put into your bladder to drain urine into a bag. Keep the bag below your waist. This will prevent urine from flowing back into your bladder and causing an infection or other problems. Also, keep the tube free of kinks so the urine will drain properly. Do not pull on the catheter. This can cause pain and bleeding, and may cause the catheter to come out.
- Pain medicine: Caregivers may give you medicine to take away or decrease your pain.
- Do not wait until the pain is severe to ask for your medicine. Tell caregivers if your pain does not decrease. The medicine may not work as well at controlling your pain if you wait too long to take it.
- Pain medicine can make you dizzy or sleepy. Prevent falls by calling a caregiver when you want to get out of bed or if you need help.
- Blood thinners help prevent blood clots. Blood thinners may be given before, during, and after a surgery or procedure. Blood thinners make it more likely for you to bleed or bruise.
- Heart medicine: This medicine is given to strengthen or regulate your heartbeat. It also may help your heart in other ways. Talk with your caregiver to find out what your heart medicine is and why you are taking it.
- Blood pressure medicine: This is given to lower your blood pressure. A controlled blood pressure helps protect your organs, such as your heart, lungs, brain, and kidneys. Take your blood pressure medicine exactly as directed.
- Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.
- Antiplatelets help prevent blood clots. This medicine makes it more likely for you to bleed or bruise.
Preventing blood clots:
Around the time of your surgery or procedure you may need to take medicine to thin your blood. Blood thinning medicine helps prevent blood clots from forming in your veins. This medicine makes it easier for a person to bruise and bleed. You will need regular blood tests while taking this medicine. If you have a bleeding disorder or a history of bleeding or blood clots, tell your caregiver. Talk to your caregiver about all of the medicines that you use. Physical activity helps prevent blood clots. Caregivers will help you be as active as possible after your surgery or procedure.
- You may bleed more than you should during or after surgery, and need a blood transfusion or more surgery. After your surgery, you may get an infection or have a stroke. Your new valve may not work right, or over time the new valve or area around it may become damaged. The new valve may be too small and worsen your condition. The problem you had before the surgery may come back or may still be there after surgery. You may need to have heart valve surgery again. Your heart may not beat as it should after surgery. Your heart may stop working.
- After surgery, you may get a blood clot in your leg or arm. The blood clot can break loose and travel to your lungs. This problem can be life-threatening. You may need to take medicine to prevent blood clots for the rest of your life after your surgery. Without surgery, you may get short of breath or tired more often. Blood and fluid could build up in your lungs, and your heart may start to fail.
