What are heart valves Heart valves are like one way doors that control the direction of blood flow between the four chambers of the heart There are two upper chambers the atria and two lower chambers the ventricles see the diagram on page 2 The atria receive blood from the body and pump it into the ventricles The ventricles pump blood away from the heart to the rest of the body For more information on this topic please call 1300 36 27 87 With each heartbeat blood is squeezed from the atria into the ventricles and then out of the ventricles to the rest of the body After each contraction of the atria or the ventricles the inner flaps of the valves often called cusps or leaflets come together to seal off the chambers of the heart and make sure that the blood does not flow backwards They are forced open again by the normal pumping action of the heart to allow forward blood flow The four heart valves are the tricuspid valve on the right side of the heart which controls the blood flow between the right atrium and the right ventricle the mitral valve on the left side of the heart which controls the blood flow between the left atrium and the left ventricle the pulmonary valve on the right side of the heart which separates the right ventricle and the pulmonary artery the blood vessel that carries blood from the heart to the lungs the aortic valve on the left side of the heart which separates the left ventricle and the aorta Heart Foundation Heart valve surgery Page 1

The diagram below shows the four chambers of the heart and the location of the valves It also shows using arrows how blood flows through the heart Pulmonary artery Blood that has circulated through your body has had most of its oxygen and nutrients removed It returns into the right atrium passes through the tricuspid valve into the right ventricle and is then pumped through the pulmonary valve into the vessels leading to your lungs The lungs add needed oxygen to the blood and remove carbon dioxide waste Now the blood returns to your heart flowing from the lungs into the left atrium From the left atrium the blood passes through the mitral valve into the left ventricle Finally it s pumped through the aortic valve into blood vessels supplying the rest of your body Page 2 Heart Foundation Heart valve surgery

What is heart valve surgery Heart valve surgery is an operation to fix a damaged or faulty heart valve It usually takes between four and six hours There are two main types of heart valve surgery that you can have valve repair and valve replacement Valve repair Sometimes a faulty valve can be repaired by cutting away excess tissue in the cusps of the valve and sewing the edges together It can also be repaired by shortening or connecting the cords that act like hinges on the valve Special rings called prosthetic rings or annuloplasty rings see diagram below can also be used to narrow an enlarged valve and strengthen the repair Another method used to open a narrowed valve is called balloon valvotomy In this procedure a small tube a catheter is inserted into an artery in your arm or groin and guided into your heart Once it is positioned within the problem valve a special balloon at the tip of the catheter is inflated to stretch open the valve The catheter and balloon are then removed An advantage of valve repair operations is that usually your own valve tissues are used in the repair Heart Foundation Heart valve surgery Page 3

Valve replacement If a valve can t be repaired it is sometimes removed and replaced with a new valve The new valve is sewn onto a rim of tissue that is kept from the original valve Several types of replacement valves are used They fall into two groups Biological tissue valves These are human or animal valves Animal valves usually taken from a cow or pig are mounted in a cloth covered metal or plastic frame to make them easier to insert Human valves are taken from donated human hearts and can be sewn directly into place Mechanical valves These have some advantages over tissue valves because they last longer However blood clots can form on the synthetic material To overcome this anti clotting medicine see page 12 needs to be taken for life What happens during heart valve surgery During the operation your surgeon will cut down the midline of your chest through your breastbone to reach your heart Your body will be kept cool to protect your vital organs by slowing down their working rate so that they need less oxygen A heart lung machine will take over the function of your heart and lungs A note about blood transfusions If you object to having blood transfusions please tell your doctor and surgeon before surgery Page 4 If you need a blood transfusion all blood products used for transfusion in Australia are strictly screened to protect patients against viruses that can cause hepatitis and AIDS Sometimes you can arrange to donate some of your own blood before you have surgery so that you can use it if you need a blood transfusion However this isn t always possible Heart Foundation Heart valve surgery

Why do I need heart valve surgery You need heart valve surgery because your heart valves are not working properly and your doctor has diagnosed you with heart valve damage Sometimes people are born with damaged valves which may be fixed soon after birth or later in life Disease or infection can also damage your valves Rheumatic fever is a frequent cause of valve damage It makes a valve gradually become stiff so that it doesn t open and close properly A damaged valve that limits forward blood flow by not opening properly is called a stenotic valve see diagram below A damaged valve that doesn t close properly allowing blood to flow back into the chamber is called an incompetent valve or a regurgitant valve Often both conditions are present When a valve is damaged your heart cannot pump blood efficiently It has to work harder to deliver oxygen rich blood around your body An overworked heart may begin to weaken causing shortness of breath pain tiredness and a build up of fluid in the body If this happens the valve may have to be replaced or repaired see pages 3 and 4 Heart Foundation Heart valve surgery Page 5

What will happen after heart valve surgery After the operation you will be taken to a recovery area or intensive care unit for close supervision until you wake up from the anaesthetic You will probably stay in the intensive care unit for one or two days After the intensive care unit you will be moved to another ward until you are ready to go home Before you leave hospital your doctor will make follow up appointments for you to discuss your medicines wound care and activities with them Your cardiologist will continue to oversee your general heart health Your first outpatient appointment will usually be two to four weeks after you leave hospital About four to six weeks after leaving hospital you will see your surgeon or a member of the surgical team Your doctor will check your wound and general progress and you may also have an X ray at this time Will I feel pain after the operation Quick tip Sitting up and moving your arms and shoulders frequently may help to reduce your soreness You will probably feel quite sore especially in the first few days after the operation You will be given painkillers regularly to make sure that you don t feel severe pain If the pain starts to build up tell your nurse sooner rather than later You and your nurse need to communicate and manage your pain together Medicine won t get rid of all of your pain but it can manage it Stronger painkilling medicines are needed for only a few days so there is very little risk of becoming addicted to them How long will I have to stay in hospital This varies depending on your condition and your response to surgery On average after heart valve surgery people stay in hospital for six to nine days Page 6 Heart Foundation Heart valve surgery

How long will it take to recover from heart valve surgery Normal recovery from heart surgery takes four to six weeks During this time you will begin to strengthen your muscles and return to your usual activities Soon after your operation your chest wound will be exposed to the air allowing it to dry After a few days the wound can be cleaned Sometimes wire or special strips of tape are used to hold the breastbone together These do not need to be removed It takes about six to 12 weeks for the breastbone to heal completely During that time you shouldn t lift anything heavy After major surgery such as heart valve surgery recovery time may seem to pass slowly Your body has been slowed down by the lowered activity lack of good sleep medicines and the surgery itself You may feel drained physically and emotionally Some hospitals run outpatient rehabilitation programs These can be a very important part of your recovery and will help you to continue the gradual increase in activity you began in hospital When can I start eating again After the operation while you are still under the anaesthetic a breathing tube is put into your windpipe The tube is usually removed within eight to 24 hours and most of that time you will have been asleep After the tube is removed you will be able to swallow a small amount of liquid and build up to foods over the next couple of days Heart Foundation Heart valve surgery Cardiac rehabilitation The Heart Foundation and World Health Organization recommend that all patients who have had a heart attack heart surgery coronary angioplasty angina or other heart and blood vessel disease attend an appropriate cardiac rehabilitation and prevention program Page 7

What should I be eating Enjoying a variety of foods from the different food groups is the key to healthy eating Choose m ainly plant based foods such as vegetables fruit legumes e g chick peas kidney beans baked beans and lentils and plain unsalted nuts w holegrain cereal foods such as breakfast cereals bread pasta noodles and rice m oderate amounts of lean unprocessed meats skinless poultry and reduced fat dairy products fish include a 150 gram serve in two or three meals per week Want to know more Call 1300 36 27 87 foods with low or reduced salt content and foods labelled no added salt low salt or salt reduced p lant based oils such as canola sunflower soybean olive and peanut oils What if I am constipated Unfortunately many pain relieving tablets can make you constipated The best remedy is to eat high fibre foods such as bran seeds fruit and vegetables and drink plenty of fluids aim for 6 8 glasses per day Follow your exercise program because exercise will help promote regularity How active can I be This will depend on your recovery You will probably start just by sitting in a chair or walking around the room Later there will be short walks in the corridor and eventually stair climbing and brisk longer walks to prepare for home Sponge baths are given right away and within a few days you will be able to take a shower and wash your hair Page 8 Heart Foundation Heart valve surgery

When can I be more physically active Once you are at home continue with the level of activities that you started in hospital Aim to progress your activity gradually over the weeks and months ahead as advised by your surgical team Set realistic goals for yourself Don t over do it but don t be inactive either Rest when you need to and change an activity if it is making you too tired Doing too much at this time won t injure the heart It will however make you very tired If you experience chest wound complications such as redness or weeping and or movement of the breastbone you should contact your surgical team for advice You may need to stop your activity or take it a bit more slowly and allow more time for healing As you become more active during your recovery you will probably get some pain associated with the wound or muscles in your chest shoulder neck and back Continue to take your pain relieving tablets e g paracetamol when you need them You will be able to reduce these gradually Don t neglect any type of severe pain When can I have sex If you can climb one flight of stairs without getting chest pain or shortness of breath you will probably be able to cope with the amount of energy required for sex Avoid having sex after eating a large meal drinking alcohol or when you are very tired You may find that some positions are more comfortable than others because of discomfort in your chest wound It can take time for sexual relationships to get back to normal after surgery so try to take things slowly Make an effort to discuss your feelings and concerns with your partner Heart Foundation Heart valve surgery Page 9

Why am I so tired Quick tip It s important that you are free of pain when you go to bed so that you get a good night s sleep You might find it helpful to learn relaxation techniques or listen to relaxation tapes Tiredness is very common after surgery and it s important that you rest Have a one to two hour rest in the afternoon Even if you don t sleep lie down and read a book or listen to relaxing music Try to get eight to 10 hours of sleep every night Sometimes you may get breathless when you exercise This is to be expected but if it continues after you have rested or is associated with heart flutters tell your doctor Breathlessness can be a symptom of heart attack see page 12 Why do I feel great one day but dreadful the next Quick tip In the first few weeks after surgery you might have trouble with your memory and concentration This will improve steadily and should not be a problem Up and down days after surgery are normal The best way to overcome this is to plan something interesting to do each day Don t alter your normal lifestyle too much either Get out of bed at the usual time and dress in day clothes When can I return to work This decision is usually made after your four to six week check up It will depend on your type of work how demanding your job is your strength and other factors Office workers can usually return to work in six weeks If your work is more physically demanding you should follow your surgeon s advice Palpitations Many people have palpitations thumping heartbeats or fluttery feelings after operations Usually this is not serious If you are having palpitations often or they last a long time tell your doctor Page 10 Heart Foundation Heart valve surgery

Heart attack A heart attack is an emergency Getting to hospital quickly can reduce the damage to your heart and increase your chance of survival A heart attack happens when there is a sudden complete blockage of an artery that supplies blood to your heart muscle a coronary artery As a result some of your heart muscle starts to die If the artery stays blocked the lack of blood permanently damages the area of your heart muscle that is supplied by that artery It is important that you know what to do if you or someone else has a heart attack Will you recognise your heart attack Do you feel any pain pressure heaviness tightness In one or more of your chest neck jaw arm s back shoulder s You may also feel nauseous a cold sweat dizzy short of breath Yes 1 STOP 2 TALK and rest now Tell someone how you feel If you take angina medicine Are your symptoms severe or getting worse Take a dose of your medicine 5 minutes Still have symptoms Take another dose of your medicine Wait 5 minutes Symptoms won t go away Wait or Have your symptoms lasted 10 minutes Yes 3 CALL 000 Triple Zero Ask for an ambulance Don t hang up Wait for the operator s instructions If calling Triple Zero 000 does not work on your mobile phone try 112 2010 National Heart Foundation of Australia ABN 98 008 419 761 Heart Foundation Heart valve surgery Page 11

Endocarditis Infection Call your cardiologist or surgeon straight away if you have any symptoms of an infection such as fever sweating loss of appetite weight loss or an overall lack of energy lasting more than a week People who have heart valve disease or who have had heart valve surgery are at greater risk than others of an infection called endocarditis Endocarditis occurs when bacteria pass through the bloodstream and settle on the valve This can cause very serious problems To prevent endocarditis your cardiologist may tell you to take antibiotics before certain dental and surgical procedures and in some cases childbirth If you take antibiotics the risk of infection in these circumstances is very small If you re not sure what antibiotics you should take or when you should take them ask your doctor or surgeon Will I need to take medicine If you have had a valve replacement you may need to take an anti coagulant anti clotting medicine These medicines stop the blood clotting easily and are used to prevent clots forming on your new valve Warfarin is the most commonly used anti coagulant Some types of valve replacement require only two or four months of anti coagulant treatment but others require lifelong treatment These medicines don t stop clotting completely but reduce the risk of problems that can be caused by blood clots forming on your new valve Page 12 Heart Foundation Heart valve surgery

Important things to remember about anti coagulant medicine Don t stop taking anti coagulants without talking to your doctor first Don t change the amount of medicine that you are taking without talking to your doctor first Try to take your medicine at the same time every day preferably in the evening If you miss a dose take it as soon as you remember on the same day If you don t remember until the next day don t take an extra dose but talk to your doctor If you go away make sure that you take enough medicine with you To make sure that you take the right dose of medicine you will need to have frequent blood tests to check the time it takes clots to form While you are still in the hospital after your operation your doctor or nurse will probably test your blood daily When you go home at first you should have a blood test once a week Later it may only need to be once every four to six weeks While you are taking anti coagulants be on the alert for signs of bleeding and tell your doctor about any unusual bleeding or bruising As other medicines can interfere with anti coagulants don t take any medicine that your doctor hasn t prescribed This includes over the counter medicines such as cough medicines For minor aches and pains take paracetamol not aspirin or ibuprofen as these may affect clotting Some people may be prescribed a regular dose of aspirin in addition to warfarin If this is the case it is important not to take extra aspirin for aches and pains If you are taking warfarin you should limit the amount of alcohol that you consume because it can alter the effectiveness of the medicine If you need dental work or surgery tell your dentist or surgeon that you are taking anti coagulants They may tell you to temporarily stop taking them Heart Foundation Heart valve surgery Page 13

If you are planning a long trip before you leave ask your doctor to help you to make arrangements to have any necessary blood tests during your trip Always carry with you information about your medicine and the dose that you are taking Some foods can interfere with the way warfarin works in the body See the box below for further information Warfarin and food People taking warfarin need to be aware that certain types of foods can either enhance or inhibit the effects of the medicine Foods high in vitamin K such as leafy green vegetables can reduce the effect of warfarin while some dietary supplements may increase the effects of warfarin It is important to remember that these foods should not be avoided altogether but that people taking warfarin should try to keep their intake of these foods fairly consistent Foods to be aware of include leafy green vegetables such as spinach broccoli lettuce cabbage asparagus parsley watercress and brussels sprouts c anola olive and soybean oils s eaweed such as in sushi g reen and herbal teas liver s pring onions People taking warfarin should talk to a doctor first if they are considering changes to their eating habits for example switching to a vegetarian diet following a special meal plan to lose or gain weight or starting or discontinuing any dietary supplements such as fish oil supplements For more information contact the NPS Medicines Line on 1300 633 424 Page 14 Heart Foundation Heart valve surgery
