At a glance
Valve repair or replacement is open-heart or minimally invasive surgery that fixes or replaces a faulty heart valve so blood flows through the heart in the right direction and at the right pressure. The heart has four valves: the mitral, tricuspid, aortic, and pulmonary. Each one opens and closes with every heartbeat to keep blood moving forward. When a valve becomes too narrow (stenosis) or leaks backward (regurgitation), the heart has to work much harder, which over time weakens the heart muscle.
In a repair, the surgeon reshapes, trims, or reinforces the existing valve, often adding a ring around its base to hold it in the correct shape. In a replacement, the damaged valve is removed entirely and swapped for either a mechanical valve made of durable materials or a biological valve taken from animal tissue or a human donor. Mechanical valves last longer but require the patient to take blood thinners for life; biological valves usually do not require long-term blood thinners but may wear out after ten to twenty years.
Medical Condition
Doctors recommend valve repair or replacement when a diseased valve causes symptoms or when tests show the heart is being damaged even before symptoms appear. The most common culprits are age-related calcium build-up, rheumatic fever (an inflammatory complication of streptococcal throat infection), and congenital abnormalities (defects present from birth).
- Aortic stenosis: the aortic valve narrows, blocking blood flow out of the heart to the body.
- Mitral regurgitation: the mitral valve leaks, letting blood flow backward into the lungs.
- Mitral stenosis: the mitral valve narrows, restricting blood flow from the lungs into the heart.
- Aortic regurgitation: the aortic valve leaks, causing the heart to pump the same blood twice.
- Tricuspid regurgitation: the tricuspid valve leaks, often alongside left-sided valve disease.
- Infective endocarditis (bacterial infection of the valve) that has destroyed valve tissue.
- Congenital valve defects, such as a bicuspid aortic valve (a valve that has two leaflets instead of the normal three).
Not every patient with valve disease is a suitable candidate for surgery. Doctors weigh up overall health, heart function, and the risk of operating before making a recommendation.
- Very advanced heart failure where the heart is too weak to survive surgery.
- Severe frailty or multiple serious illnesses that make the surgical risk unacceptably high.
- Mild valve disease with no symptoms and no sign of heart damage, where watchful waiting is preferred.
Risks & Complications
Like all open-heart procedures, valve surgery carries recognised risks that the surgical team discusses with the patient beforehand.
- Bleeding during or after surgery, sometimes requiring a transfusion.
- Stroke (a blockage or bleed in the brain) caused by small clots forming during surgery.
- Atrial fibrillation (an irregular, rapid heartbeat) in the days after surgery, which is common and usually temporary.
- Infection of the wound, lungs, or the new valve itself (prosthetic valve endocarditis).
- Kidney injury from reduced blood flow during the procedure.
- Heart rhythm disturbances that may require a temporary or permanent pacemaker.
- Valve repair failure requiring a second procedure or conversion to replacement.
- Structural deterioration of a biological replacement valve over time.
- Risks from the heart-lung bypass machine, including temporary memory or thinking problems.
- In rare cases, death, particularly in patients who are already very unwell before surgery.
Preparation & Procedure
Preparation begins days to weeks before surgery and involves both lifestyle steps and medical testing. Smoking damages the heart and lungs and slows healing, so patients are asked to stop as far in advance as possible. Alcohol is usually stopped at least a week before. The team will give specific fasting instructions, but in most hospitals solid food is stopped from midnight the night before and clear liquids are stopped a few hours before the scheduled start time.
Several medications are paused before surgery. Blood thinners, anti-inflammatory drugs such as aspirin, and some diabetes medications are typically stopped in the days leading up to the procedure. The surgical team provides a personalised list. Patients should bring all current medications to every pre-operative appointment so the team can review everything.
A standard pre-operative workup for valve surgery usually includes the following tests.
- Echocardiogram (an ultrasound of the heart) to measure how badly the valve is affected and to assess overall heart function.
- Electrocardiogram, or EKG (a tracing of the heart's electrical activity) to check for rhythm problems.
- Chest X-ray to look at the size of the heart and the condition of the lungs.
- CT scan or cardiac MRI to map the anatomy of the heart and major blood vessels before surgery.
- Coronary angiography (an X-ray of the heart's arteries using dye) to check whether bypass surgery is also needed.
- Blood tests including a full blood count, kidney and liver function, blood type, and clotting ability.
- Dental check-up, because tooth infections can spread to a new valve and are ideally treated before surgery.
On the day of surgery, the patient changes into a hospital gown and an intravenous line is placed in the arm. The procedure itself follows these main steps.
- General anaesthesia (medication that puts the patient into a deep sleep) is given so the patient feels nothing.
- The surgeon makes an incision in the chest, either down the breastbone or through a smaller cut at the side, depending on the approach agreed upon.
- The heart is connected to a heart-lung bypass machine, which takes over the job of pumping and oxygenating blood while the surgeon works.
- The heart is stopped temporarily using a cold solution so the surgeon can work on the valve without it moving.
- The surgeon repairs the existing valve or removes it and secures the replacement valve in place with sutures or clips.
- The heart is restarted, the bypass machine is disconnected, and the surgical team confirms the valve is working correctly using a transoesophageal echocardiogram (an ultrasound probe passed down the throat).
- The chest is closed in layers and drains are placed to remove any fluid that collects around the heart.
Aftercare
Recovery from valve surgery is a gradual process that takes place first in an intensive care unit (ICU) and then on a general cardiac ward before the patient goes home. The total hospital stay varies, but most patients spend at least several days in hospital after surgery. Once home, physical activity is reintroduced slowly over several weeks, and a full return to normal life typically takes two to three months, though individual recovery differs.
- ICU monitoring: the patient wakes up connected to a ventilator (breathing machine), heart monitors, and drainage tubes. These are usually removed within the first day or two as the patient stabilises.
- Pain management: chest discomfort is normal and is managed with prescribed pain relief so the patient can breathe deeply and cough to keep the lungs clear.
- Breathing exercises: a physiotherapist usually teaches deep-breathing exercises in hospital to reduce the risk of pneumonia (lung infection).
- Wound care: the chest incision is kept clean and dry. The patient is told which warning signs, such as redness, discharge, or fever, mean the wound needs to be checked urgently.
- Blood thinners: patients who receive a mechanical valve take blood thinners lifelong and require regular blood tests to keep the level within a safe range. Patients with biological valves usually take them for a shorter period.
- Activity restrictions: lifting heavy objects and driving are restricted for several weeks. The cardiac team sets milestones based on how the individual is healing.
- Cardiac rehabilitation: a structured exercise and education programme is often recommended to help the heart recover and to reduce the risk of future problems.
- Antibiotic prophylaxis (preventive antibiotics before dental or certain medical procedures): patients with replacement valves are usually advised to take antibiotics before specific procedures to prevent bacteria from settling on the new valve.
- Follow-up appointments: echocardiograms and clinic visits are scheduled at regular intervals to check that the repaired or replaced valve continues to work well.
- Lifestyle: a heart-healthy diet, maintaining a healthy weight, staying physically active as cleared by the doctor, and not smoking all support long-term recovery.
Cost & What Determines It
Valve repair or replacement is one of the more complex cardiac surgeries, and its cost reflects that complexity. Two patients with valve disease can face very different bills depending on factors that are specific to their situation, the hospital they choose, and the country they travel to.
- Type of valve involved and severity of disease: a heavily calcified aortic valve or a valve damaged by infection requires more complex work than a straightforward repair, affecting both operating time and cost.
- Repair versus replacement: repair is technically more demanding but avoids the cost of an implant; replacement adds the price of the prosthetic valve itself.
- Type of replacement valve: mechanical valves and high-quality biological valves, including those from human donors, differ considerably in price.
- Whether a minimally invasive approach is available: smaller incisions require specialised equipment and may be offered only at certain hospitals, which can affect the fee.
- Whether coronary artery bypass surgery is performed at the same time, which lengthens the operation and increases cost.
- Hospital class and country: a private tertiary hospital in a major city charges more than a public or mid-tier hospital, and prices differ significantly between countries.
- Length of ICU and ward stay: complications that extend the stay add daily bed, nursing, and monitoring costs.
- Post-operative medications: long-term blood thinners, anti-rejection drugs if applicable, and other cardiac medications contribute to the total.
- Pre- and post-operative investigations: echocardiograms, CT scans, angiography, and laboratory tests are often billed separately from the surgical fee.
- Cardiac rehabilitation programme, if taken as an in-patient or outpatient course after discharge.
A hospital package for valve surgery typically covers the surgeon's fee, anaesthesia, the operating theatre, the implant or prosthetic valve, ICU care, and the standard ward stay. Items commonly billed separately include pre-admission testing, specific imaging studies ordered during recovery, additional specialist consultations, and the cost of medications to take home.
For Indonesian patients, BPJS Kesehatan and most Indonesian private insurance policies do not cover treatment received abroad, which means the full cost is usually paid out of pocket or through an international private health insurance plan that explicitly includes overseas care. Before travelling, ask the hospital for a detailed written cost estimate that lists what is included in the package and what may be charged additionally. Having this in writing before you leave Indonesia is the most reliable way to budget accurately and avoid unexpected bills on return.
Frequently Asked Questions
How long does valve repair or replacement surgery take?
The operation usually takes between three and six hours, depending on whether the valve is being repaired or fully replaced and how many valves are involved. Your surgical team will also spend time connecting you to a heart-lung bypass machine, which keeps blood circulating while the heart is briefly stopped. Complex cases or additional procedures on the heart can extend the time in the operating room.
What kind of anaesthesia is used, and will I feel pain during or after?
You will be under general anaesthesia, meaning you will be completely unconscious and feel nothing during the surgery itself. Afterwards, most patients feel soreness around the chest incision and sometimes in the shoulders, which the care team manages with pain relief medication. The discomfort usually eases over the first week or two as the wound begins to heal.
How long is recovery, and when can I go back to work?
Most patients stay in the hospital for about one to two weeks, including a short period in the ICU (intensive care unit) directly after surgery. Light activity at home is usually possible within four to six weeks, but returning to a physically demanding job or heavy lifting typically takes two to three months. Your cardiologist and surgeon will guide you based on how your heart responds during follow-up checks.
How much does valve repair or replacement surgery cost?
The cost varies depending on several factors specific to this procedure, including whether the valve is repaired or replaced, the type of replacement valve used (a mechanical valve or a tissue valve), the length of your ICU and hospital stay, and the class of hospital you choose. Getting a written estimate directly from the hospital is the most reliable way to understand what your care will cost.
