TAVI

What is TAVI ?

TAVI stands for Transcatheter Aortic Valve Implantation, also known as Transcatheter Aortic Valve Replacement (TAVR). It is a minimally invasive surgical procedure used to treat aortic valve stenosis, which is a condition where the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body.

During a TAVI procedure, a new artificial valve is implanted within the existing aortic valve using a catheter-based approach. The procedure typically involves accessing the heart through a blood vessel in the groin or chest, rather than through open-heart surgery. The replacement valve is compressed and delivered to the site of the diseased valve, where it is expanded and secured in place. This helps to restore normal blood flow through the aorta and the rest of the body.

TAVI is considered a less invasive alternative to traditional open-heart surgery for patients who may not be suitable candidates for surgery due to various reasons such as age, medical conditions, or other factors. It offers several potential benefits, including shorter recovery times, reduced hospital stays, and lower risks of complications. However, like any medical procedure, it also carries its own set of risks, which should be evaluated by healthcare professionals on a case-by-case basis.

TAVI prices

The cost of a Transcatheter Aortic Valve Implantation (TAVI) procedure can vary significantly depending on several factors, including the country or region where the procedure is performed, the specific hospital or medical facility, the complexity of the case, the type of valve used, and any additional medical services or post-operative care required. Insurance coverage and individual circumstances can also influence the final cost. The price of a TAVI starts at 20.000 USD.

What are the different stages of the TAVI procedure ?

The Transcatheter Aortic Valve Implantation (TAVI) procedure typically involves several stages, which may vary slightly depending on the specific approach and technique used.

Here are the general stages of a TAVI procedure :

Pre-procedure Assessment : Before the TAVI procedure, the patient undergoes a comprehensive evaluation, which may include medical history review, physical examination, imaging tests (such as echocardiography and computed tomography), and additional cardiac assessments to determine the suitability for TAVI ;
Anesthesia : The patient is usually given a local anesthesia to numb the insertion site and a mild sedative to help them relax during the procedure. In some cases, general anesthesia may be used ;
Access Site Preparation : The doctor identifies the appropriate access site, typically in the groin area (transfemoral approach) or in the chest (transapical or transaortic approach). The chosen site is cleaned, sterilized, and numbed with a local anesthetic ;
Catheter Insertion : A catheter, a thin, flexible tube, is inserted through the chosen access site and guided towards the aorta and the diseased aortic valve. This is typically done using fluoroscopy (real-time X-ray guidance) and, in some cases, additional imaging techniques such as transesophageal echocardiography ;
Valve Deployment : Once the catheter is positioned at the site of the aortic valve, the replacement valve, which is typically compressed onto a balloon, is advanced through the catheter and positioned within the diseased valve. The balloon is then inflated, expanding the new valve and pushing aside the diseased valve leaflets, securing the replacement valve in place. Alternatively, some TAVI systems use a self-expanding valve that is released without the need for balloon inflation ;
Valve Assessment and Function: After the new valve is in place, its position and function are assessed using imaging techniques such as echocardiography or angiography. The doctor ensures that the valve is properly functioning, with improved blood flow and minimal leakage ;
Catheter Removal and Closure : Once the valve is confirmed to be functioning well, the catheter and other instruments are carefully removed. The access site is then closed using closure devices or manual pressure, depending on the access site and the medical team’s preference ;
Recovery and Monitoring : The patient is moved to a recovery area where they are monitored for a certain period to ensure stability and proper healing. The duration of this monitoring period may vary depending on the medical team’s assessment ;

It’s important to note that the above stages are a general overview, and the specific details may differ based on individual patient factors, medical team preferences, and advancements in TAVI techniques. The procedure should always be performed by experienced healthcare professionals in specialized cardiac centers.

What are the advantages and risks of the TAVI procedure

Transcatheter Aortic Valve Implantation (TAVI) offers several advantages over traditional open-heart surgery for the treatment of aortic valve stenosis. However, it is important to consider the associated risks as well.

Here are the advantages and risks of the TAVI procedure :

What are the advantages of TAVI

Minimally Invasive : TAVI is a minimally invasive procedure, which means it can be performed without the need for open-heart surgery. This results in smaller incisions, reduced trauma to the chest, and potentially faster recovery times compared to traditional surgery ;
Suitable for High-Risk Patients : TAVI is a valuable option for patients who are considered high-risk or inoperable for open-heart surgery due to factors such as advanced age, frailty, or other underlying health conditions. TAVI allows these patients to receive aortic valve treatment when surgery may not be a viable option ;
Shorter Hospital Stay : TAVI often allows for shorter hospital stays compared to open-heart surgery. Patients may be able to return home within a few days after the procedure, promoting a faster recovery ;
Faster Recovery : TAVI typically involves a quicker recovery period compared to open-heart surgery. Patients may experience less pain and discomfort and resume their normal activities sooner ;
Less Trauma and Blood Loss : TAVI involves smaller incisions, resulting in less trauma to the body and potentially reduced blood loss during the procedure ;

What are the risks of TAVI

Vascular Complications : TAVI requires accessing the heart through blood vessels, typically in the groin or chest. This can pose a risk of vascular complications such as bleeding, damage to blood vessels, or development of blood clots ;
Valve-related Issues : While rare, there can be complications associated with the replacement valve itself. These may include valve leakage (paravalvular leak), valve malposition, valve dislodgement, or structural deterioration of the valve over time ;
Stroke : There is a small risk of stroke during or after the TAVI procedure, primarily due to the manipulation of catheters within the aorta and potential dislodgment of debris or clots that can travel to the brain ;
Arrhythmias : TAVI can occasionally lead to irregular heart rhythms (arrhythmias), including atrial fibrillation, which may require additional treatment ;
Other Complications : As with any medical procedure, there is a risk of infection, bleeding, damage to surrounding tissues, adverse reactions to anesthesia or medications, and other potential complications ;

It’s important to note that the risks and benefits of TAVI should be assessed on an individual basis, taking into consideration the patient’s specific condition, overall health, and other factors. The decision to undergo TAVI should be made in consultation with a healthcare professional who can provide personalized recommendations and discuss the potential risks and benefits in detail.

How is recovery after a TAVI procedure?

After the Transcatheter Aortic Valve Implantation (TAVI) procedure, patients typically go through a recovery and monitoring phase.

Here’s an overview of what happens after the TAVI procedure :

Recovery Room : Following the procedure, the patient is moved to a recovery area or an intensive care unit (ICU) where they are closely monitored by medical professionals. Vital signs, such as blood pressure, heart rate, and oxygen levels, are monitored to ensure stability ;
Hospital Stay : The length of the hospital stay after TAVI can vary depending on individual factors, the specific procedure, and the medical team’s evaluation. In some cases, patients may be discharged within a few days, while others may require a slightly longer hospital stay for additional monitoring or recovery ;
Medications : Patients are usually prescribed medications to support their recovery and manage their condition. This may include antiplatelet medications to prevent blood clots, anticoagulants, beta-blockers, and other medications to control blood pressure and manage any underlying cardiac conditions ;
Post-Procedure Assessment : During the hospital stay, the medical team will perform regular assessments to evaluate the functioning of the new valve, monitor the patient’s overall condition, and identify any potential complications or issues that may require further treatment or intervention ;
Follow-up Appointments : After being discharged from the hospital, patients are typically scheduled for follow-up appointments with their healthcare provider. These appointments allow for ongoing evaluation of the patient’s progress, assessment of the valve’s function, monitoring of medications, and addressing any concerns or questions the patient may have ;
Cardiac Rehabilitation : In some cases, patients may be recommended to undergo a cardiac rehabilitation program. This program involves supervised exercise, lifestyle counseling, and education to help improve cardiovascular health, enhance recovery, and promote overall well-being ;
Long-term Monitoring : Patients who have undergone TAVI will require ongoing monitoring of their ;
Cardiac health : This may involve regular follow-up visits with a cardiologist, periodic echocardiograms or imaging tests, and adjustments to medications as needed ;

It’s important for patients to follow the post-procedure instructions provided by their healthcare team, including taking prescribed medications, adhering to lifestyle modifications, and attending scheduled appointments. This helps ensure proper healing, ongoing management of the condition, and long-term success of the TAVI procedure.
