The aortic valve plays a crucial role in regulating blood flow within the heart. It’s one of the heart’s four valves and acts as a gate between the heart’s lower left chamber, known as the left ventricle, and the body’s principal artery, the aorta. As the heart contracts, the aortic valve swings open, allowing blood to flow from the left ventricle into the aorta. Then, as the heart relaxes, the valve closes, ensuring that blood doesn’t flow back into the heart.
If the aortic valve becomes damaged or diseased, it can disrupt this essential flow of blood. Such a malfunction may force the heart to exert more effort to distribute blood throughout the body. The valve could either become constricted, limiting the blood flow, or it may not close properly, causing blood to leak in the wrong direction. Some individuals might even have congenital heart issues from birth that impact the valve’s functioning.
To address these challenges, aortic valve repair or replacement procedures can be done. These interventions aim to enhance blood circulation, alleviate symptoms associated with heart valve issues, and ultimately extend one’s lifespan.
There are two primary surgical interventions to address pathological conditions of the aortic valve:
Several factors play a role in determining the type of surgery required, including:
Aortic valve disorders can lead to severe complications, such as heart failure, stroke, and sudden cardiac arrest. The two primary treatments for these conditions are aortic valve repair and replacement. While individuals with mild aortic valve disease may only need regular medical checkups, severe cases usually require surgical intervention.
The primary aortic valve conditions are:
The decision between valve repair or replacement depends on:
Valve repair is generally preferred by surgeons since it preserves the natural heart valve, reduces infection risk, and can enhance heart performance. However, the suitable treatment varies based on the specific issue and the medical team’s proficiency.
Aortic valve surgery, as with other surgical procedures, comes with its own set of potential risks. These can include:
However, it’s worth noting that certain individuals may face a heightened risk of these complications based on various factors such as:
Before undergoing aortic valve repair or replacement surgery, your medical team will guide you through the entire process, detailing what will occur pre-operatively, intra-operatively, and post-operatively, while also highlighting the potential risks associated with the procedure. It’s essential to communicate with your caregivers prior to your hospital admission about the upcoming stay and to plan any assistance you might require upon returning home.
Prior to your surgery, your healthcare provider might request certain preoperative tests. These tests could include:
Your healthcare provider will provide detailed instructions which are crucial for you to adhere to. These guidelines will specify:
Upon reaching the hospital for your surgery, a medical specialist will insert an intravenous (IV) line into your forearm or hand. This IV will be used to deliver fluids and medicines. If necessary, they might also shave or trim hair around the area where the surgery will be conducted. For valve repair and replacement surgeries, it’s standard to administer general anesthesia, which ensures you’re in a deep, painless slumber throughout the procedure. During this surgery, you might be connected to a heart-lung bypass machine, guaranteeing uninterrupted blood flow in your body.
Aortic valve repair typically requires open-heart surgery, where the chest bone or sternotomy is opened. After the procedure, surgeons use wires to join the bone back to facilitate healing.
There are various methods of aortic valve repair, including:
Balloon valvuloplasty is a less invasive procedure intended to fix an aortic valve that doesn’t open completely due to stenosis. This procedure usually means smaller cuts and a quicker hospital recovery.
In this technique, a surgeon threads a catheter, a thin hollow tube, from a blood vessel in the groin up to the heart. A balloon attached to the catheter’s end is then inflated to expand the constricted valve.
This method is commonly used for children and infants with aortic valve stenosis. However, for adults, the valve may narrow again post-procedure, so it’s generally reserved for those too ill for surgery or those awaiting valve replacement. Follow-up procedures might be required.
Replacement heart valves can sometimes leak or deteriorate. In such cases, either a surgery or a catheter procedure might be performed to mend or seal a leaking replaced heart valve.
Should the aortic valve be beyond repair, a replacement becomes necessary. The faulty valve is removed and substituted with either a mechanical one or a biological tissue valve sourced from cows, pigs, or human donors. In some instances, a person’s pulmonary valve can be used as a replacement.
Mechanical valves necessitate lifelong blood-thinning medication to avert blood clots. On the other hand, biological valves may wear out and require future replacements.
Aortic valve replacements can be achieved through traditional open-heart surgery or through minimally invasive techniques. One such method is the Transcatheter aortic valve replacement (TAVR), also known as Transcatheter aortic valve implantation (TAVI).
The outcomes of minimally invasive aortic valve replacements, when conducted by seasoned surgeons in specialized centers, are comparable to those of conventional open-heart surgeries.
After undergoing an aortic valve repair or replacement, you’ll likely stay in the intensive care unit (ICU) for at least a day. In the ICU, you’ll be administered fluids, nutrition, and medications through intravenous (IV) lines. Additionally, tubes will be in place to drain urine from your bladder and excess fluid or blood from your heart and chest, with oxygen supplied if necessary. Once stabilized, you’ll be shifted to a standard hospital room for several days, though the exact duration of your hospital stay, encompassing both the ICU and regular room, will depend on your health and the specifics of your procedure.
Throughout your hospitalization, the medical team will:
The length of recovery is determined by the type of procedure, your pre-surgical health, and any complications after the surgery. Once discharged, you might be recommended to refrain from driving and from lifting objects heavier than 10 pounds for several weeks.
Following aortic valve repair or replacement surgery, your healthcare professional will provide guidance on when you can resume daily activities, including work, driving, and exercise.
Regular checkups will be necessary to monitor your heart’s condition and to detect any potential complications, such as valve malfunction. Imaging tests may be conducted to ensure the proper functioning of the aortic valve.
Maintaining a heart-healthy lifestyle is crucial after heart valve surgery, and your healthcare provider may advise the following lifestyle adjustments:
Furthermore, your healthcare provider may recommend participation in a cardiac rehabilitation program. This program combines education and exercise to enhance your overall health and facilitate your recovery following aortic valve surgery.
