Aortic stenosis is one of the most serious valve conditions, where a narrowing of the aortic valve restricts blood flow from the heart to the rest of the body. If left untreated, severe aortic stenosis can lead to heart failure, stroke, and other life-threatening complications.

Traditionally, patients with severe aortic stenosis have been treated with open-heart surgery to replace the damaged valve. While it may be effective, open-heart surgery may not be suitable for everyone, especially older adults or patients with multiple health conditions. Today, Transcatheter Aortic Valve Implantation, commonly known as TAVI, has been developed, which offers a minimally invasive alternative that has transformed the treatment of aortic valve disease.

What Is TAVI?

TAVI, also called TAVR (Transcatheter Aortic Valve Replacement), is a procedure used to replace a narrowed or damaged aortic valve without opening the chest through conventional open-heart surgery. Because the procedure avoids major surgical incisions, TAVI is considered minimally invasive. Patients often experience less pain, shorter hospital stays, and faster recovery compared to traditional surgery.

Understanding Aortic Stenosis

The aortic valve controls blood flow from the heart into the aorta, the body’s main artery. In aortic stenosis, the valve becomes stiff and narrowed, making it harder for the heart to pump blood effectively. This condition is commonly linked to ageing and calcium buildup on the valve. It may also develop due to congenital heart defects, rheumatic heart disease, or previous radiation therapy.

Symptoms may develop gradually and are sometimes mistaken for general ageing-related fatigue. Common signs include:

• Chest pain or tightness
• Shortness of breath
• Fatigue during physical activity
• Dizziness or fainting
• Rapid or irregular heartbeat
• Swelling in the legs or feet

Once symptoms become severe, timely treatment becomes essential.

Who Is a Candidate for TAVI?

TAVI was initially developed for patients considered high-risk for open-heart surgery. Over time, advances in technology and growing clinical evidence have expanded its use to many patients with severe aortic stenosis.

A cardiology team carefully evaluates each patient before recommending TAVI. Factors considered include:

• Age and overall health
• Severity of aortic valve disease
• Existing medical conditions
• Heart function
• Surgical risk assessment
• Imaging and diagnostic test results

Many elderly patients benefit from TAVI because it reduces the physical stress associated with conventional surgery. However, younger patients may sometimes be advised to undergo surgical valve replacement depending on long-term treatment considerations. 

How Is the Procedure Performed?

• Before the procedure, patients undergo several investigations such as echocardiography, CT scans, blood tests, and cardiac evaluations to help doctors plan treatment accurately.
• Under local anaesthesia with sedation or sometimes under general anaesthesia, the catheter is inserted through an artery, most commonly in the groin, and advanced toward the heart using imaging guidance.
• The replacement valve, made from biological tissue, is positioned within the damaged valve. Depending on the valve type, it is either expanded using a balloon or self-expanded into position.
• Once the new valve is functioning properly, the catheter is removed, and the incision site is closed.

The procedure typically takes a few hours, and many patients are able to sit up and walk within a day.

 Benefits of TAVI

One of the biggest advantages of TAVI is that it offers effective treatment without the trauma of major surgery. For suitable patients, the procedure provides several important benefits:

• Smaller incisions and minimal scarring
• Reduced pain after the procedure
• Shorter hospital stay
• Faster recovery and return to daily activities
• Lower risk of complications in selected patients
• Improvement in symptoms such as breathlessness and fatigue
• Better quality of life

Many patients notice a significant improvement in energy levels and physical activity after recovery.

Recovery After TAVI

Recovery after TAVI is generally quicker than recovery after open-heart surgery. Most patients spend a short period in intensive monitoring before being shifted to a regular room.

Doctors monitor heart rhythm, blood pressure, and valve function carefully after the procedure. Patients are usually advised to:

• Take prescribed medications regularly
• Attend follow-up appointments
• Follow a heart-healthy diet
• Avoid smoking and excessive alcohol intake
• Engage in gradual physical activity as recommended
• Control blood pressure, diabetes, and cholesterol levels

Cardiac rehabilitation may also be recommended for some patients to support long-term heart health.

Are There Any Risks?

Like all medical procedures, TAVI carries certain risks, although it is considered safe and highly effective when performed by experienced specialists.

Potential complications may include:

• Bleeding
• Infection
• Stroke
• Irregular heart rhythm
• Blood vessel injury
• Valve leakage
• Need for pacemaker implantation in some cases

Careful patient selection and advanced imaging techniques have significantly improved outcomes over the years.

 Advanced Structural Heart Care at STAR Hospitals

STAR Hospitals offers comprehensive cardiac care supported by experienced cardiologists, cardiac surgeons, interventional specialists, advanced imaging, and modern catheterisation laboratories.

The cardiac sciences departments at STAR Hospitals are equipped to manage complex heart conditions using advanced interventional and surgical techniques, with a strong focus on patient safety, precision, and recovery. For patients with severe aortic stenosis and other structural heart conditions, the hospital provides detailed evaluation, risk assessment, minimally invasive treatment planning, and post-procedure care under a multidisciplinary heart team.

Remember, early diagnosis and timely treatment can make a major difference in outcomes for patients with valve disease. Individuals experiencing symptoms such as unexplained breathlessness, chest discomfort, dizziness, or fatigue should seek medical evaluation without delay.
