Discover how TAVR offers a less invasive option for replacing a diseased aortic valve, reducing recovery time and improving patient outcomes.

What Is the TAVR Procedure?

Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure designed to treat severe aortic valve stenosis—a narrowing of the aortic valve that restricts blood flow from the heart to the rest of the body. Unlike traditional open-heart surgery, TAVR replaces the diseased valve using a catheter threaded through a small incision, often in the leg or chest. This innovation allows for quicker recovery and is especially beneficial for patients at high surgical risk.

Why Is TAVR Done?

TAVR is primarily performed to treat aortic stenosis, a serious heart valve disease in which the aortic valve becomes stiff or calcified and cannot open fully. This limits the amount of blood that can reach the body, leading to symptoms and possible life-threatening complications. Left untreated, severe aortic stenosis can result in heart failure, arrhythmia, stroke, or even sudden cardiac death.

Symptoms indicating aortic valve disease: Shortness of breath, chest pain, fainting spells, fatigue, and palpitations.
Primary goals of TAVR: Restore proper blood flow from the heart, relieve symptoms, and improve quality of life.

Who Is a Candidate for TAVR?

TAVR is appropriate for certain patients diagnosed with severe aortic stenosis, especially those who are:

At high or intermediate risk for open-heart surgery due to age or coexisting conditions
Not candidates for open surgery because of prior chest operations or frailty
Seeking a less invasive solution for valve replacement

Your heart team will evaluate your overall health, age, medical history, and valve anatomy to determine if TAVR is right for you. Even some patients at low to moderate risk have been considered eligible as studies show consistent benefits in these groups.

How to Prepare for the TAVR Procedure

Preparation for TAVR involves a thorough evaluation by a team of cardiac specialists. This evaluation may include:

Imaging studies: Echocardiogram, CT scan, or cardiac catheterization to assess the heart and blood vessels.
Blood tests: To evaluate overall health and detect possible infections.
Medication review: Discussion of all medications and supplements currently taken. Some may need to be stopped or adjusted before the procedure.
Fasting: You may be required to avoid food and drink for several hours before the procedure.
Consent: The risks and benefits will be discussed, and you’ll be asked to sign consent forms.

Step-by-Step: What Happens During TAVR?

The TAVR procedure typically takes about one to two hours and involves several critical steps, usually performed in a specialized catheterization laboratory (cath lab) or a hybrid operating room.

Anesthesia: You’ll receive either general anesthesia or conscious sedation to ensure comfort throughout the procedure.
Vascular access: A small incision is made, most often in the groin (femoral artery), though sometimes in the chest or neck, to insert the catheter.
Navigation to the heart: The catheter, equipped with the replacement valve, is threaded through your blood vessels and guided to the heart.
Valve positioning: X-ray and echocardiogram imaging guide the precise placement of the new valve inside your native aortic valve.
Valve deployment: The new valve is expanded (using a balloon or self-expands) and takes over the job of regulating blood flow. The old, stiff valve is pushed aside, while the new one starts functioning immediately.
Catheter removal and closure: The catheter is carefully removed and the incision site is closed.

The team will monitor your vital signs and the function of the new valve throughout the procedure. If necessary, additional procedures may be performed to address complications such as bleeding or irregular heartbeat.

Comparing TAVR and Traditional Open-Heart Surgery

Feature	TAVR	Open-Heart Surgery
Approach	Minimally invasive, catheter-based	Major surgery, chest opened
Anesthesia	Conscious sedation or general	General anesthesia
Surgical Trauma	Minimal	Significant, longer healing
Hospital Stay	Short (often 1–3 days)	Longer (5–10 days typical)
Recovery Period	Rapid (1–2 weeks)	Several weeks to months
Candidates	Ideal for high-risk or elderly patients; now used in moderate- and some low-risk patients	Best for younger, healthier candidates
Outcome Efficacy	Comparable or superior at 3 years for some patients	Long-term data well established

Benefits of TAVR

Less invasive: No need for opening the chest or placing the patient on a heart-lung machine
Faster recovery: Shorter hospital stay and quicker return to everyday activities—often within days to a couple of weeks
Symptom relief: Reduced shortness of breath, chest pain, and fatigue after the procedure
Improved quality of life: Most patients experience better exercise tolerance and daily function
Suitable for high-risk groups: Especially beneficial for elderly and frail patients or those with prior heart surgeries

Risks and Potential Complications

As with any medical procedure, TAVR carries some risks. The overall risk profile depends on a patient’s health, age, and whether they have existing conditions or risk factors.

Stroke
Major bleeding or vascular injury
Heart rhythm problems, sometimes requiring a pacemaker
Kidney injury
Heart attack
Valve leakage (paravalvular leak)
Death (rare, but a possible risk in invasive cardiac procedures)

Most serious complications are rare, especially with improvements in technology and procedure technique. Your team will provide preventive treatments and monitor for any adverse events.

What to Expect After TAVR

After the procedure, you will be moved to a cardiology recovery area where your vital signs, heart function, and access site are monitored. Most patients can:

Stand and walk within one day
Go home in one to three days
Resume normal activities in one to two weeks, as tolerated and as advised by your doctor

Follow-up appointments are important to ensure the new valve continues to function well and to monitor for late complications. Your doctor may recommend:

Limiting strenuous activity briefly after discharge
Taking blood thinners or other medications
Periodic echocardiograms
Heart-healthy lifestyle changes, including nutrition, exercise, and smoking cessation

Frequently Asked Questions about TAVR

Is TAVR the same as open-heart surgery?

No. TAVR is a minimally invasive alternative to open-heart surgery for treating aortic stenosis. It uses a catheter to replace the diseased valve, eliminating the need to open the chest or stop the heart.

How long does the TAVR procedure take?

The procedure often takes 1 to 2 hours, significantly shorter than open-heart surgery, which may last 4 hours or more.

What is the recovery time after TAVR?

Most patients go home within 1 to 3 days and can return to many of their usual activities within one to two weeks, depending on their health and response to the procedure.

Who is not a good candidate for TAVR?

Patients with active infection, certain anatomical variations (like very small or large valves), or other severe cardiac or vascular conditions may not be eligible for TAVR. Always consult with your heart team for a personalized assessment.

Are the results of TAVR long-lasting?

The new valves used in TAVR are designed to be durable. Current evidence shows comparable results to surgical valves at 3 years for many patients; research on longer-term durability is ongoing.

What lifestyle changes are needed after TAVR?

A heart-healthy diet, regular physical activity, avoiding tobacco, and adherence to prescribed medications are recommended to ensure the best long-term outcome after TAVR.

When to Call Your Doctor

After TAVR, seek medical attention immediately if you experience:

Sudden chest pain or shortness of breath
Severe or persistent bleeding at the incision site
Loss of consciousness or severe dizziness
Fever or signs of infection

For any questions or symptoms that concern you, contact your cardiac care team for guidance.

Key Points to Remember

TAVR is a game-changing minimally invasive option for aortic valve replacement, especially for high-risk and elderly patients.
Most patients recover faster and with fewer complications than with traditional open-heart surgery.
Eligibility depends on an in-depth evaluation by your heart team.
Regular follow-up and healthy lifestyle support the best long-term outcomes.

Additional Resources

Discuss all your options and concerns with your cardiologist or cardiac surgeon.
Request information about support groups and recovery programs for cardiac patients in your area.
The American Heart Association and professional heart societies offer up-to-date patient guides on TAVR and heart valve disease.
