What To Expect From Aortic Root Surgery
Aortic root surgery (ARS) is a procedure to repair or replace the aortic root. There are various types of ARS surgery that come with different risks and benefits.
The aorta is a large blood vessel that transports oxygenated blood from the heart to the rest of the body. An aortic root aneurysm (ARA) is an abnormal swelling in the beginning or "root" section of the aorta, which attaches to the heart.
This article provides an overview of ARS, outlines the risks and benefits, and discusses what to expect before, during, and after the procedure. It also considers the outlook after surgery and offers advice on when to contact a doctor.
The aorta is the largest blood vessel in humans, carrying oxygenated blood from the heart to the rest of the body.
An aortic aneurysm (AA) is an abnormal swelling in the wall of the aorta. There are two main types:
An ARA is a type of thoracic AA since it involves swelling of the aortic root — the junction where the aorta meets the heart. One of the heart's four valves — the aortic valve — sits inside this junction. Its job is to prevent oxygenated blood from flowing back into the heart.
According to the Massachusetts General Hospital, most ARAs involve an abnormality of the aortic valve. Examples include aortic stenosis, where the valve does not open properly, and aortic regurgitation, where the valve does not close properly.
Aortic root surgery typesARS repairs or replaces the aortic root. There are two types of surgery:
When performing ARS, surgeons may opt for one of two approaches: open heart surgery or endovascular aneurysm repair (EVAR). According to the Vascular Society for Great Britain and Ireland, EVAR involves making an incision in the groin and inserting a plastic tube or stent up through the aorta and into the aneurysm, using X-rays for guidance.
When deciding whether a person is a suitable candidate for ARS, healthcare professionals will typically compare the relative risks and benefits.
The decision to proceed with surgery will largely depend on the urgency of the situation. A ruptured thoracic aneurysm is a medical emergency that requires immediate surgical intervention, whereas a small aneurysm may not require surgery unless it enlarges.
According to the American Heart Association, healthcare professionals typically recommend aortic root surgery for ARAs with a diameter of 5 centimeters (cm) or more.
People at increased risk of surgical complications may reserve surgical intervention for ARAs measuring at least 6 cm. However, surgery may be necessary for ARAs smaller than 5 cm across if the person is experiencing symptoms or has an underlying condition that increases the risk of an aortic rupture.
The National Heart Lung and Blood Institute (NHLBI) lists some general risks associated with heart surgery. These include:
Bentall procedureA 2023 study of the Bentall procedure for ARA found that the procedure was associated with a mortality rate of 1.38%, indicating that almost 99% of people survived the initial surgery.
The Bentall procedure involving aortic valve replacement may pose additional risks. According to the United Kingdom's National Health Service, these may include:
Data from 2012 states that the mortality rate of the David procedure ranges from 1.7–2.8%. This means that the majority of people who undergo this procedure survive.
Possible risks and complications of the procedure include:
These complications are uncommon outcomes of this surgery, however.
The majority of ARSs are currently open heart surgeries. Below are some general guidelines on what to expect before, during, and after open heart surgery, according to the NHLBI. The exact procedure may differ somewhat, depending on the type of ARS a person receives.
BeforePrior to surgery, a person will receive general anesthesia, which will make them unconscious and unable to feel any pain.
DuringTo begin the procedure, the surgeon will make a 6–8 inch incision down the center of the chest and will cut through the breast bone. They will then open up the ribcage to access the heart.
The surgeon will then connect the heart to a heart-lung bypass machine, which takes over the heart's function. The machine diverts blood away from the heart so it no longer needs to pump blood and can remain completely still.
For ARS, the surgeon places clamps across the aorta, then removes the damaged section and stitches a synthetic graft in its place between the remaining aorta and aortic valve. In the Bentall procedure, the surgeon may also remove an aortic valve and replace it with a mechanical valve or a bioprosthetic valve made from animal tissues.
Once the surgery is complete, the surgeon will restore blood flow to the heart.
AfterFollowing the surgery, a person will typically remain in the intensive care unit (ICU) for a day or more for observation.
During this time, a person may receive intravenous fluids and extra oxygen via a face mask or nasal prongs that fit inside the nostrils.
After leaving the ICU, a person will generally spend several days in another part of the hospital for continued observation and recovery, during which their healthcare team will closely monitor the following:
A person's surgeon will advise them when they are ready to go home.
A 2022 longitudinal study investigated outcomes in 217 people who had undergone the Bentall procedure for ARA. According to the study, almost 99% of people survived the initial surgery. At 7-year follow-up, 93% of people were still alive, and 81% of these had not experienced a recurrence of ARA.
Information from 2012 states that the general outcome of the initial surgery using the David procedure is positive. This same information shows that in people who received surgery using the David procedure, between 87% and 98% were free from the need for reoperation in the 10–15 years following initial surgery. Between 64% and 95% were free from moderate to severe aortic insufficiency 10–15 years after surgery.
A person should contact a healthcare professional if they experience symptoms of thoracic AA. According to the British Heart Foundation, a large thoracic AA may cause the following symptoms:
However, it is important to note that a thoracic AA usually does not cause any symptoms, and healthcare professionals discover most cases during investigations for other conditions. This means people should consider speaking with a healthcare professional if they are at increased risk of developing a thoracic AA.
People who may be at a higher risk of thoracic AA include:
Below are some answers to common questions about ARS.
How risky is aortic root surgery?Aortic root surgery is a type of heart surgery. As the NHLBI explains, heart surgery is associated with certain risks, including:
Heart surgery also carries a risk of death, though this is more likely in people who are very ill prior to the surgery.
What is the life expectancy after aortic root replacement?Life expectancy following aortic root replacement may differ according to various factors, including:
A 2023 longitudinal study noted that almost 99% of people who received surgery for ARA survived the procedure, and 93% of these individuals were alive at 7-year follow-up.
A 2023 meta-analysis investigated outcomes in people undergoing ARR with mechanical valves versus bioprosthetic valves. The study found that ARR using mechanical valves was associated with better long‐term outcomes than ARR using bioprosthetic valves.
Is aortic root surgery open heart?While less invasive, endovascular options for ARS are under investigation, the procedure currently remains an open heart operation.
Aortic root surgery (ARS) is a type of heart surgery that involves repairing or replacing the aortic root of the aorta. This is the part of the aorta that connects to the heart.
As with any heart surgery, the procedure carries certain risks, including bleeding, blood clots, and death. When deciding whether to perform ARS, doctors will compare the potential risks and benefits.
Typically, they will reserve ARS for emergencies, large aortic aneurysms, and cases where a person experiences symptoms or has an underlying medical condition that increases their risk of aortic rupture.
Factors that can affect outcomes for ARS include the person's overall health, the type of ARS they have, and whether the procedure also involves an aortic valve replacement. Anyone who is considering surgery for an aortic root aneurysm should speak with their cardiologist for further advice and guidance.
What Is Aortic Stenosis?
Aortic stenosis is a condition that occurs when the opening of the aortic valve becomes narrowed. The aortic valve is a heart valve that helps direct blood flow from the heart to the rest of your body. When the valve becomes too narrow it limits blood flow through the heart and to the main artery (blood vessel) that supplies oxygen-rich blood to the body (the aorta). This condition can also affect the pressure within the heart's left upper chamber (the left atrium).
Some people are born with a condition known as a bicuspid aortic valve, which can lead to aortic stenosis. But for many, this condition occurs later in life, often due to aging. An estimated 2% to 9% of people over the age of 75 years experience severe aortic stenosis. For those who experience aortic stenosis later in life, calcium buildup and scarring in the blood vessels can harm the valve. This makes it harder for blood to pass through the valve.
Many people with aortic stenosis may not show any clear symptoms until the condition severely limits blood flow. For some, symptoms may not begin until after the age of 50. When symptoms of aortic stenosis do appear they can include: Chest pain or discomfort Heart palpitations Shortness of breath Fainting Dizziness Difficulty walking or exercising without feeling exhausted Swelling in the ankles or feet Trouble sleeping unless sitting up Lethargy or fatigue Chronic cough that sometimes occurs with coughing up blood Children who are born with a bicuspid aortic valve have a higher risk of developing aortic stenosis. If your child has this condition, they may experience the following symptoms: Extreme fatigue Difficulty gaining weight as expected Challenges with feeding properly Breathing difficulties that emerge within days or weeks after birth Some people are born with a defect in the aortic valve, which can eventually cause aortic stenosis. For people born with a bicuspid aortic valve, your heart valve has two flaps instead of three, which increases the risk of heart valve problems. This is the most common cause for younger people with aortic stenosis. However, if you develop this condition as you get older, several factors can contribute to the onset of symptoms. One common cause is a buildup of calcium in the valve, which can cause hard deposits in your blood vessels and limit blood from flowing effectively. Other conditions, including rare metabolic disorders, autoimmune disorders (like lupus), and end-stage kidney disease, can contribute to calcium buildup in your heart valve. Risk Factors Certain factors can cause a rapid decline in your heart function and increase your risk of developing symptoms of aortic stenosis, such as: Aortic stenosis can worsen your heart health, so getting a timely diagnosis is essential. Diagnosing aortic stenosis usually begins with a physical exam. Your healthcare provider often detects a heart murmur, a clicking sound, or other unusual heart sounds using a stethoscope. Signs such as a weak pulse, low blood pressure, or changes in the pulse's strength in the neck can also be signs of this condition. To confirm a diagnosis of aortic stenosis, your healthcare provider will likely order a specific heart imaging test known as a transthoracic echocardiogram (TTE). A TTE is a non-invasive diagnostic test that uses ultrasound waves to create images of the heart. The purpose of this scan is to measure the size and performance of the heart's four chambers. Additional tests that your provider may order include: Electrocardiogram (ECG): Records the heart's electrical activity Exercise stress testing: Assesses how the heart functions under physical stress Left cardiac catheterization: Examines the heart's chambers and blood flow Heart MRI: Provides detailed images of the heart's structure and function Transesophageal echocardiogram (TEE): Gives a closer look at the heart's valves and chambers from inside the esophagus If symptoms are mild, regular appointments with a healthcare provider may be sufficient for monitoring aortic stenosis. During these visits, your healthcare provider may review your personal medical history, conduct a physical examination, and order an echocardiogram to review your heart health and assess the severity of your condition. However, if you have severe aortic stenosis, your provider will often recommend that you limit strenuous physical activity and avoid competitive sports to prevent added strain to your heart. Healthcare providers also recommend managing high cholesterol and quitting smoking. However, some cases of aortic stenosis require treatment, which may include medications or surgical procedures. Medications Prescription medications can help manage symptoms and reduce the risk of heart failure or irregular heart rhythms, such as atrial fibrillation. Your provider may recommend one or more of the following drug types: Diuretics to reduce fluid buildup Nitrates to improve blood flow Beta-blockers to reduce heart strain Managing high blood pressure is also important, but should be approached with caution. That's because severe aortic stenosis can sometimes cause blood pressure to fall too low. Surgical Procedures For both adults and children who experience symptoms of aortic stenosis, surgery to repair or replace the affected valve is a common treatment option. Sometimes, even if the symptoms are mild, healthcare providers may suggest surgery based on the findings of your diagnostic testing. There are several surgical approaches for replacing a damaged valve, including: Mechanical valve: Involves using a valve made from durable materials Tissue valve: Uses a heart valve made from human or animal donor tissue Ross procedure: Relocates a healthy valve in your heart to replace the damaged valve and uses a new and healthy heart valve to replace the relocated heart valve Balloon valvuloplasty: Inserts a balloon through an artery in the groin and into the heart to inflate and widen the valve opening Transcatheter aortic valve replacement (TAVR): Implants an artificial valve through a catheter Aortic stenosis often results from age-related changes or congenital conditions (conditions that are present at birth) that cannot be completely prevented. While a healthy lifestyle (such as getting exercise, eating a low-cholesterol diet, and abstaining from cigarette smoking) may reduce some risk factors, unfortunately, the development of aortic stenosis itself may not always be avoidable. Several conditions can occur alongside aortic stenosis. These include: Heart failure: Your heart's pumping ability can decrease, which affects how much blood your heart can deliver to other organs in your body Pulmonary hypertension: Also known as high blood pressure in the lungs, this condition can occur due to increased pressure in the heart caused by aortic stenosis Infective endocarditis: An infection of the heart's inner lining or valves, which is generally more common among people with a bicuspid aortic valve Aortic stenosis develops when your heart's aortic valve narrows. This is often due to calcium buildup in the heart's aortic valve or from being born with a condition like a bicuspid aortic valve. While prevention may be a challenge, advancements in medical treatments can help manage this condition effectively. Early detection is key and implementing lifestyle factors like eating a low-cholesterol diet and quitting smoking can help manage your overall heart health.Thanks for your feedback!
