Getting a heart valve replacement is a procedure that replaces a damaged heart valve. This procedure is performed to restore the function of the heart valve and to prevent the valve from becoming a blockage that would lead to heart failure. The procedure can be done either surgically or through a bioprosthesis.
Mechanical
Surgical management of valvular heart disease is associated with high morbidity and mortality. Mechanical heart valve replacement is an effective treatment option for valvular heart disease patients, offering a better quality of life. However, complications can occur, and management is crucial for better clinical outcomes.
Blood clots are a complication of mechanical heart valves. These clots can block blood flow and cause heart attacks. Antithrombotic therapy is important to prevent clots from forming and traveling to other organs. However, anticoagulants have their own side effects.
In addition to bleeding, other complications can occur, including thromboembolism and infective endocarditis. These complications can occur when a replacement valve is improperly oriented or when a thread or suture is loose. The risk of bleeding is reduced when the patient self-manages their anticoagulation therapy.
In this study, 121 patients with CHD underwent mechanical prosthetic valve replacement. The aim was to assess the clinical outcomes of mechanical valve implantation in children. The patients were followed for 8 years. The information was drawn from patient records.
Patients were followed at an outpatient clinic. The records included comorbidity, aortic valve interventions, and the most recent visit. If further follow-up was necessary, patients were followed at a later date.
The study aimed to identify risk factors for reoperations. Younger age was an independent predictor of reoperations.
The study found that thromboembolic complications occurred at a rate of 0.66% per patient year. The incidence of complications was higher in patients with autoimmune thrombocytopenia. These patients have a reduced platelet count which can contribute to the risk of bleeding.
Although mechanical heart valve replacement is a life-saving procedure, it requires patients to take blood thinners for the rest of their lives. Patients also need regular blood tests.
Bioprosthetic
Surgically implanted bioprosthetic heart valves are not typically used to replace mechanical heart valves. The two types of valves have different advantages and disadvantages. Surgically implanted bioprosthetic valves are less likely to cause blood clots than mechanical valves. However, they are not as durable as mechanical valves.
Bioprosthetic heart valves are a better choice for older patients. Generally, bioprosthetic valves last for a period of 10-20 years. However, this period of time may not be enough for some patients. The valve may eventually degenerate, meaning that it will have to be replaced.
Mechanical heart valves last for a longer period of time. They can last up to 20-30 years. However, mechanical valves require blood-thinning medication for the rest of the patient’s life. These medicines can have negative side effects and can also cause bleeding.
Bioprosthetic heart valves do not usually require blood thinning medication. However, they do require a long period of monitoring. Blood clots can block arteries, leading to stroke. Depending on the patient’s health, the surgeon will decide which type of valve is best for the patient.
If a person needs dialysis, a bioprosthetic heart valve may be more appropriate. In addition, younger patients with bleeding disorders may need a bioprosthetic heart valve. The surgery will also improve the quality of life for the patient.
The ESC/EACTS guidelines do not recommend oral anticoagulants as a treatment for patients with surgically implanted bioprosthetic heart Valves. However, some patients with atrial fibrillation may benefit from oral anticoagulants. However, this is not a universal recommendation.
Surgically implanted bioprosthetic and mechanical heart valves are both durable, but they do have disadvantages. Mechanical valves are less ideal for younger patients, and require lifelong blood thinning medication.
Percutaneous
Unlike open heart surgery, percutaneous heart valve surgery is less invasive and requires less time. The procedure entails replacing the damaged aortic valve through a blood vessel. There are several different models of valve replacement and repair. These procedures include non-surgical cardiac valve repair, vascular stents, and self-expanding valve systems.
The Cribier-Edwards percutaneous aortic heart valve is a proprietary technology developed with Alain Cribier, M.D., at the University Hospital in Rouen. The system integrates the aortic heart valve with balloon-expandable stent technology. The procedure is performed under local anesthesia and without open chest surgery.
The Cribier-Edwards system has been successfully implanted in 7 high-risk surgical patients. It has also been tested in animal models.
The Cribier-Edwards valve consists of an irradiated platinum stent inserted by a 22 mm balloon with a direct needle puncture. This technique was developed to treat severe aortic stenosis without the need for open chest surgery.
The Everest II study has been completed and the results are impressive. The device is 24 Fr in diameter and requires transesophageal echocardiography under general anesthesia. This method is less invasive than open heart surgery and has a lower adverse event rate.
At 12 months, both groups showed improvement in quality of life measurements. In addition to a lower adverse event rate, both groups had improved left ventricular size. In addition, both groups improved their NYHA functional class.
The first patient of the Hufnagel procedure survived for 7 years. This was an impressive result for the first patient of the procedure. Although the procedure was only tested in animals, the results indicate that it may be used in humans.
This procedure has proven effective in pulmonary valve procedures, and tricuspid valve procedures. Because of the low morbidity and mortality rates associated with this procedure, it has become one of the most popular procedures for these two heart valves.
Mitral
During mitral heart valve replacement, your doctor will remove the diseased valve and replace it with a new one. This procedure can add years to your life. It also helps to improve your quality of life.
The procedure is usually carried out under general anesthesia. Your doctor will check your heart rate, blood pressure, and vital signs. He or she will tell you when you can return to regular activities. You will likely receive medications to help you relax.
The surgery can take several hours. Depending on your condition, you may be admitted to a hospital for several days. The duration of the stay depends on your health and the complexity of the operation.
In the hospital, you may have a breathing tube put in your chest. You may also be given a drain tube. These tubes drain urine from your bladder and the fluids in your chest. Usually, the tube is removed within 24 hours.
You will likely have to wear elastic stockings and compression devices. You will also need to take blood-thinning medicine for the rest of your life.
There are several types of valves. Some are artificial, while others are biological. Mechanical valves last longer than others, but they also cost more.
For patients with narrow valves, a catheter procedure may be the best option. This type of procedure involves a thin tube that is passed through a blood vessel to the heart. The catheter is guided to the mitral valve by advanced imaging. The catheter’s inner circle contains a new bovine-tissue valve, while the outer meshwork fully covers the diseased valve.
The procedure is much less invasive than open heart surgery. This can make recovery faster and easier for patients.
Pulmonary
Unlike mechanical heart valves, which are made from artificial materials, pulmonary heart valve replacements are generally made from animal tissue. Typically, pulmonary valve replacements are performed through open heart surgery. However, minimally invasive pulmonary heart valve replacement procedures are also available. These procedures are not as common as open heart surgeries, but they can be a good alternative for patients who do not want to undergo open heart surgery.
These pulmonary heart valve replacement procedures can be performed through a minimally invasive transcatheter approach. This method requires less anesthesia and faster recovery than open heart surgery. However, pulmonary valve replacement devices are not always long-lasting, and patients may need to have multiple replacements over the course of their lifetime.
The first transcatheter pulmonary heart valve replacement was performed on a five-year-old boy from East Haven, CT. The patient was discharged from the hospital the following day. A week later, he was back at work and in the gym.
The patient was implanted with a new heart valve, the first patient in the United States to receive the valve. He underwent a short procedure near Halloween. He had an overnight stay but was discharged home the following day.
The patient had pulmonary valve atresia, a condition where the valves of the heart become damaged or dysfunctional. He had two valves, a mechanical one and a biological one. He had to take blood-thinning medication for the rest of his life.
In the United States, 18 patients have successfully been implanted with Xeltis’ restorative pulmonary valve. These devices are made of polymers and are approved by the FDA. In addition, the device is approved for use in the European Union, Japan, and Canada.
