How to Prepare for a TAVR Procedure: Tests, Medicines and Pre-Procedure Planning

Preparing for TAVR is not simply about arriving at the hospital on the procedure date. Transcatheter aortic valve replacement, also called TAVI, depends on detailed planning before the new valve is implanted. The medical team needs to confirm that treatment is necessary, understand the patient’s anatomy, identify conditions that could increase risk and choose the correct valve and access route.

For patients and families, knowing what happens before the procedure can reduce uncertainty and make it easier to follow instructions correctly.

Confirm the Diagnosis and Treatment Plan

The first step is confirming severe aortic stenosis and establishing that valve replacement is appropriate. Echocardiography measures how narrowed the valve has become and evaluates how the heart is pumping.

Symptoms such as breathlessness, chest pain, fainting, dizziness, fatigue and reduced exercise capacity are reviewed alongside the scan findings. The Heart Team also considers age, other illnesses, previous cardiac procedures and the advantages and disadvantages of TAVR compared with surgical valve replacement.

A complete pre-operative workup for TAVI should therefore answer both “Can this procedure be performed?” and “Is this the right procedure for this patient?”

CT Imaging for TAVR Planning

CT imaging is central to modern TAVR preparation. It provides detailed measurements of the aortic annulus, aortic root and nearby structures. The scan also shows calcium distribution and the position of the coronary arteries.

These measurements help the team select an appropriate valve size and reduce the risk of problems such as poor sealing or coronary obstruction.

The CT also evaluates the aorta and arteries in the pelvis and legs. Because most procedures use the femoral artery in the groin, the team needs to know whether the vessels are large enough and free from severe disease that could make catheter passage unsafe.

Echocardiography

A transthoracic echocardiogram is usually part of the standard evaluation. It confirms the severity of aortic stenosis, assesses heart-pumping function and identifies other valve abnormalities.

Some patients may need additional imaging, such as transoesophageal echocardiography, depending on the clinical question and local practice.

Coronary Artery Assessment

Aortic stenosis often occurs in older adults who may also have coronary artery disease. The Heart Team needs to know whether important blockages are present and whether they require treatment.

Coronary assessment may involve angiography or, in selected cases, CT-based evaluation. If significant coronary disease is identified, the timing of stenting, surgery or other treatment is considered as part of the overall valve strategy.

Blood Tests and Kidney Function

Routine blood tests help identify anaemia, infection, clotting abnormalities and problems with kidney or liver function. Kidney function is particularly important because contrast dye may be used during CT scanning and the TAVR procedure.

If kidney function is reduced, the team may modify imaging or hydration strategies and review medicines that affect the kidneys.

ECG and Heart Rhythm Review

An ECG records the heart’s electrical activity. This matters because some patients already have conduction abnormalities before TAVR, and the procedure can occasionally create new rhythm problems.

Knowing the baseline rhythm helps the team plan monitoring and assess whether the patient may have a higher chance of needing a pacemaker after valve implantation.

Medication Review

Patients should provide a complete list of prescription medicines, over-the-counter drugs and supplements. Blood thinners, antiplatelet medicines, diabetes treatments and certain blood-pressure medicines may require specific instructions before the procedure.

Never stop medication simply because another TAVR patient was told to do so. The correct plan depends on why the drug was prescribed, kidney function, bleeding risk and other medical conditions.

Patients undergoing a TAVI procedure should receive clear written instructions explaining which medicines to take, pause or adjust and when to restart them.

Dental and Infection Checks

Active infection is a concern before implantation of a prosthetic heart valve. Patients should tell the team about fever, recent infections, wounds or dental problems.

A dental assessment may be advised when there are concerns about untreated dental infection or poor oral health. Any required treatment should be coordinated with the cardiac team so that valve therapy is not delayed unnecessarily.

TAVR preparation includes understanding how well a patient functions outside the heart. Frailty, mobility, nutrition, lung disease and cognitive health can influence recovery.

This assessment helps the team determine whether valve replacement is likely to improve quality of life and whether additional support will be needed after discharge.

Practical Preparation Before Admission

Patients should confirm fasting instructions, admission time and what documents or medicines to bring. Loose clothing and basic personal items are usually sufficient because hospital stays are often relatively short when recovery is uncomplicated.

Arrange transport home and consider having a family member available during the early days after discharge. Patients should also understand likely activity restrictions and review a TAVI recovery plan before the procedure so expectations are realistic.

Questions to Ask Before TAVR

Before admission, patients should know which valve and access route are planned, what type of anaesthesia is expected and what individual risks have been identified.

It is also reasonable to ask what could cause the plan to change, how the team manages complications and who to contact after discharge.

The Bottom Line

Successful TAVR begins well before valve implantation. Echocardiography confirms disease severity, CT imaging maps the anatomy, coronary assessment identifies additional heart disease and blood tests, ECG and medical review help the team understand procedural risk.

For patients, preparation means completing these investigations, following medication and fasting instructions, treating active infection and planning for recovery at home. A well-organised pre-procedure assessment creates the information the Heart Team needs to choose the right valve, access route and treatment strategy while helping the patient enter the procedure with greater clarity and confidence.
