TAVI / TAVR

TAVI has transformed treatment for many patients with severe aortic stenosis, especially those who are older or at increased surgical risk. However, it remains a complex structural heart procedure that requires careful imaging, patient selection, and follow-up.

What Is TAVI?

TAVI places a bioprosthetic valve inside the diseased aortic valve using catheter-based delivery. The most common access route is through the femoral artery, but alternative access may be considered when leg vessels are unsuitable.

The new valve pushes aside the narrowed native valve leaflets and improves blood flow from the heart to the body. It does not remove the old valve.

Who May Be Considered?

TAVI is considered for symptomatic severe aortic stenosis and selected asymptomatic high-risk findings depending on guidelines and patient context. Age, surgical risk, frailty, anatomy, valve durability, coronary access, bicuspid valve anatomy, calcium burden, other valve disease, and life expectancy influence the decision.

Younger or lower-risk patients may still be considered for surgery depending on durability needs, anatomy, and future treatment planning. The heart team should explain why TAVI or surgery is recommended.

Pre-TAVI Assessment

Echocardiography confirming severe aortic stenosis and heart function

CT angiography for annulus sizing, calcium, coronary height, and access vessels

ECG and rhythm assessment

Coronary evaluation when indicated

Kidney function, blood tests, frailty and functional assessment

Review of anticoagulation, antiplatelets, and other medications

Dental or infection evaluation may be relevant in selected patients. Patients with active infection should not proceed electively.

Procedure and Recovery

TAVI is performed in a catheterization laboratory or hybrid operating room. The team advances the valve to the heart and deploys it under imaging guidance. Patients are monitored for rhythm changes, vascular complications, valve function, blood pressure, kidney function, and conduction abnormalities.

Hospital stay is often shorter than open surgery, but this should not be confused with being risk-free. Some patients require a pacemaker after TAVI, and others need longer observation.

Coronary Access and Future Planning

TAVI planning should consider not only today’s valve implantation but also future coronary access and future valve treatment. In younger or lower-risk patients, durability and the possibility of valve-in-valve procedures may influence whether TAVI or surgery is more appropriate.

Patients should understand that a successful TAVI procedure creates a new anatomy. Future doctors may need to know valve type, size, implant depth, coronary anatomy, and whether access to coronary arteries remains practical.

Frailty, Recovery, and Realistic Benefit

Some patients are technically eligible for TAVI but are very frail or have advanced disease affecting lungs, kidneys, brain, or general function. In these cases, the heart team should discuss whether valve treatment is likely to improve quality of life meaningfully.

A responsible recommendation balances procedural feasibility with expected clinical benefit.

Risks and Possible Complications

Vascular injury, bleeding, stroke, or kidney injury

Need for permanent pacemaker

Paravalvular leak or valve positioning concerns

Coronary obstruction in rare cases

Valve thrombosis, endocarditis, or future degeneration

Need for conversion to surgery in rare emergencies

Follow-Up After TAVI

Follow-up includes echocardiography, medication review, rhythm monitoring when needed, symptom assessment, and long-term surveillance of valve function. Patients should keep the valve type, size, implant date, and procedure report.

Medication plans vary depending on rhythm, bleeding risk, previous stents, and anticoagulation needs. Patients should not change blood thinners without cardiology guidance.

Planning Abroad Responsibly

TAVI abroad should be organized only when the patient is stable enough to travel and the pre-procedure work-up is complete. Severe symptomatic aortic stenosis can be dangerous, especially with fainting, chest pain, or heart failure symptoms, so timing must be handled carefully.

At Healing Journey, we coordinate echo images, CT planning, heart team review, hospital scheduling, travel arrangements, discharge documents, and follow-up communication with the home cardiologist.

CT Planning, Vascular Access, and Coronary Protection

TAVI planning depends heavily on CT. The team measures the aortic annulus, evaluates valve calcium, checks coronary artery height, reviews the aortic root, and confirms whether femoral arteries are suitable for access. If leg arteries are too narrow, calcified, or tortuous, an alternative access strategy may be needed or treatment may not be appropriate in that center.

Coronary access also matters after TAVI. Some patients may need future coronary angiography or stenting. Valve type, implantation depth, coronary height, and sinus anatomy can affect how easy or difficult future coronary treatment may be. This is especially relevant for younger or lower-risk patients where future lifetime management is part of the decision.

Conduction Problems and Pacemaker Risk

Some patients develop conduction disturbance after TAVI and may need a pacemaker. Baseline ECG findings, valve anatomy, calcium distribution, implantation depth, and valve type can affect this risk. Patients should understand that a shorter recovery compared with surgery does not mean there are no important post-procedure monitoring needs.

Before travelling home, the rhythm should be stable, medication instructions should be clear, and the patient should know what symptoms such as dizziness, fainting, very slow pulse, or worsening breathlessness require urgent assessment.

TAVI Is Less Invasive, Not Less Serious

TAVI often allows faster recovery than open surgery, but it is still a major heart valve intervention. It requires CT planning, vascular access assessment, valve sizing, stroke risk consideration, rhythm monitoring, kidney protection, and follow-up echocardiography. Patients should not confuse a smaller incision with a smaller medical decision.

The decision between TAVI and surgical valve replacement depends on age, surgical risk, anatomy, valve durability expectations, coronary access, other valve disease, aortic disease, frailty, and patient preference. For younger or lower-risk patients, lifetime valve strategy becomes especially important.

Lifetime Valve Strategy and Future Coronary Access

After TAVI, the patient may still need future coronary angiography, PCI, or another valve procedure later in life. Valve frame design, commissural alignment, coronary height, sinus anatomy, and implantation depth can affect future access. This is why CT planning and heart team discussion are not just technical details.

Patients should receive records of the implanted valve, size, access route, procedural result, rhythm issues, antithrombotic plan, and follow-up echo schedule. Home cardiologists need these details for future care.

Questions to Clarify Before TAVI / TAVR

Has severe aortic stenosis been confirmed by echocardiography and clinical assessment?

Does CT show suitable annulus size, coronary height, calcium pattern, and vascular access?

Is TAVI recommended over surgical replacement by a heart team, and why?

What is the estimated risk of pacemaker implantation or vascular complication?

How will valve function be monitored after the patient returns home?

TAVI is often easier to recover from than open surgery, but the decision is still complex and should be anchored in anatomy, durability, and long-term follow-up.

TAVI Follow-Up Beyond Early Recovery

Many TAVI patients feel better quickly, but early improvement does not replace follow-up. Echocardiography should assess valve function, gradients, paravalvular leak, ventricular response, and pulmonary pressures. ECG or rhythm monitoring may be needed if conduction changes occur.

The medication plan after TAVI should also be individualized. Some patients need antiplatelet therapy, some are already on anticoagulation for atrial fibrillation, and some have bleeding risk that affects the plan. The home cardiologist should receive the exact regimen and the reason for it.

What Patients Should Not Assume

Patients should not assume TAVI is appropriate for every aortic valve patient or that it is automatically better than surgery. They also should not assume that a short hospital stay means no long-term responsibilities.
