A constricted aortic valve that struggles to open adequately can be replaced with a minimally invasive operation called transcatheter aortic valve replacement (TAVR) (aortic valve stenosis). A catheter is inserted into the leg or chest and directed to the heart during this surgery by surgeons. A catheter is carefully inserted into a blood artery in your upper leg or chest and advanced towards your aortic valve during transcatheter aortic valve implantation (TAVI). The replacement valve is then fixed on top of the old ones with the aid of the catheter. In 2020, the market for transcatheter aortic valve replacement was valued at $3.9 billion. By 2027, the market is anticipated to grow at a CAGR of 13% and reach $9.3 billion.
A sternotomy, or open-heart surgery where the chest is surgically opened, is typically required for a valve replacement. However, the TAVR is still carried out through microscopic holes, leaving all the chest bones in place. In order to restore the valve’s circulatory system capabilities, it also entails implanting transcatheter aortic valves or transaortic valves.
The reason for performing the Trans Catheter aortic valve Replacement Surgery
Aortic valve stenosis is treated by transcatheter aortic valve replacement (TAVR). Aortic stenosis, also popularly known as aortic valve stenosis, happens when the aortic valve of the heart thickens and stiffens (calcifies). The valve cannot fully open as a result, and blood flow to the body is decreased.
Open-heart aortic valve replacement surgery can be substituted by TAVR. TAVR patients frequently spend less time in the hospital than those who undergo surgical aortic valve replacement. The doctor may recommend TAVR if you have:
- Signs and symptoms of severe aortic stenosis.
- A biological-tissue aortic valve that is not at all functioning properly.
- Another medical issue that renders open-heart valve replacement surgery too dangerous such as lung or kidney problems.
All the surgeries and the medical procedure carries some kind of risk. Transcatheter aortic valve replacement (TAVR) has the following potential risks: Bleeding blood, vascular problems, issues with the replacement valve, including leaks or falling out of position (regurgitation), Stroke Arrhythmias of the heart and the requirement for a pacemaker kidney illness Death, infection, and heart attack, etc.
After the conduction of the procedure
After undergoing the procedure, the patient can spend the night in the intensive care unit (ICU) for observation. Several factors determine how long you must stay in the hospital after TAVR. Some TAVR patients return home the next day.
The medical team will go over how to take care of any incisions and how to look out for infection symptoms before he or she leaves the hospital. Fever, increasing pain, redness, swelling, draining, or leaking at the catheter site are warning indications of infection.
Following TAVR, a number of drugs, including:
- Blood thinners (anticoagulants). To avoid blood clots, doctors often prescribe blood-thinning medicine. How long you an individual might need to take this medication will be explained to you by your doctor. Always take prescription drugs as directed.
• Antibiotics. Artificial heart valves are susceptible to bacterial infection. The majority of bacteria that result in heart valve infections originate in the mouth. Regular dental cleanings & good oral hygiene can help stop these illnesses. Some dental treatments call for the administration of antibiotics beforehand.
