The Heart Valve Condition That Affects Millions — and the Procedure Changing Its Outcome

Severe aortic stenosis is one of the most serious cardiac valve conditions affecting adults in India today, often requiring consultation with a TAVR expert in Hyderabad for advanced and minimally invasive treatment options. The aortic valve — which regulates blood flow from the heart to the rest of the body — progressively narrows over time, forcing the heart to work harder with every beat. Without timely treatment, the condition carries a steep prognosis: within two years of the onset of severe symptoms, more than half of untreated patients do not survive. 

For decades, the only proven treatment was open-heart surgery. For patients who were elderly, frail, or burdened by multiple co-existing illnesses, that surgery was too risky to offer. Families were told there was nothing to be done.

Transcatheter Aortic Valve Replacement—known as TAVR, or equivalently as TAVI (Transcatheter Aortic Valve Implantation)—has fundamentally rewritten that story. Understanding what TAVR is, how it works, and who it helps is now essential knowledge for every patient with aortic stenosis and every family navigating this diagnosis.

What TAVR Actually Involves

In TAVR—a cornerstone of modern TAVR cardiology—a new prosthetic aortic valve is delivered to the heart not through a chest incision, but through a thin, flexible catheter navigated from outside the body. The most common route is through the femoral artery in the groin, a blood vessel large enough to carry the crimped prosthetic valve to the heart under X-ray and ultrasound guidance.

Once the new valve reaches the diseased native valve, it is expanded — either by a small balloon or by a self-expanding mechanism — and takes over the valve’s function immediately. The diseased native valve leaflets are pushed aside; the new valve sits within them and opens and closes with each heartbeat.

No incision is made in the chest. The heart continues beating throughout. Most patients receive sedation rather than full general anesthesia. They are sitting up and taking fluids the same day. Most are discharged within two to four days.

Recovery is measured in weeks, not months. Patients who undergo TAVR at a high-quality center—performed by an experienced TAVR/TAVI specialist in Hyderabad like Dr. Raghu—typically return to normal daily activities within one to three weeks of the procedure.

TAVI and TAVR refer to the same procedure. TAVR (replacement) is the terminology used in North America; TAVI (implantation) is used widely in Europe and Asia. Clinically, there is no difference.

Why TAVR Is Particularly Significant for Indian Patients

India carries one of the world’s largest burdens of valvular heart disease. Rheumatic heart disease — historically underdiagnosed — has left a significant proportion of the older population with damaged valves. The rising prevalence of degenerative age-related aortic stenosis compounds this burden further.

Until TAVR, many of these patients were turned away. Open-heart surgery was unavailable in their region, too expensive, or too risky given their age and health. TAVR changes all three of those barriers simultaneously. It extends the eligible patient population dramatically—elderly patients, frail patients, those with prior cardiac surgery, and those with severe lung or kidney disease—all of whom previously had no safe treatment option.

A qualified TAVR/TAVI doctor in India can now evaluate these patients, most of whom can be treated safely and return to a quality of life that aortic stenosis had progressively stripped away.

The economic dimension matters too. TAVR experts in India is available at costs that are a fraction of equivalent care in the United States, the United Kingdom, or Australia—without any compromise in clinical quality at top Indian centers. This has made India an increasingly significant destination for TAVR medical tourism among overseas Indian patients and international patients seeking expert, affordable structural heart care.

The Heart Team: Why TAVR Outcomes Depend on More Than the Operator

TAVR is not a procedure performed by a single physician in a standard catheterisation laboratory. Best practice TAVR requires what is known as a Heart Team — a multidisciplinary group that evaluates every candidate collectively before any procedure is planned.

The Heart Team includes an interventional cardiologist with specific structural heart disease training, a cardiac surgeon capable of open valve replacement, a cardiac imaging specialist for echocardiography and CT planning, a cardiac anaesthesiologist, and a specialist nursing team. The team reviews each patient’s clinical and anatomical information, discusses treatment options, and arrives at a consensus recommendation.

This multi-specialist framework exists because TAVR decisions are genuinely complex. Anatomy varies between patients in ways that significantly affect both device selection and implantation strategy. Surgical risk scores must be calculated and interpreted carefully. The alternative of open surgery must be honestly assessed for each individual patient. No single clinician can make these judgments optimally in isolation.

Centres that perform TAVR without a functioning Heart Team structure are not meeting the standard established by international guidelines — and patients are entitled to ask whether the centre they are considering operates within a genuine Heart Team model.

Who Benefits Most from TAVR?

As TAVR technology and evidence have evolved, the patient population it serves has expanded. Originally introduced for patients at prohibitive or high surgical risk, the evidence base now supports TAVR in intermediate-risk and even selected low-risk patients.

Elderly patients — particularly those above 75 — are the core TAVR population. Age-related frailty and comorbidities increase surgical risk substantially, and TAVR’s minimally invasive nature is especially well-suited to this group.

High surgical risk patients—those with severe lung disease, prior cardiac surgery, renal impairment, or STS PROM surgical risk scores above 8%—are prime TAVR candidates regardless of age.

Patients who have been told they are “inoperable”—this is an important category. As TAVR technology has matured and operator experience has grown, anatomical configurations that were once considered unsuitable for TAVR are increasingly treatable. A second opinion from an experienced TAVI expert in India may reveal options that a previous evaluation missed.

Intermediate-risk patients — based on PARTNER 2 and SURTAVI trial data, TAVR produces outcomes comparable to surgery in intermediate-risk patients, expanding its appropriate use further into the mainstream valvular population.

The Evidence Behind TAVR

TAVR is one of the most rigorously evaluated interventions in modern cardiology. The PARTNER trial series, the SURTAVI trial, the EVOLUT trials, and a large body of real-world registry data have collectively established a strong evidence base for TAVR across risk strata. Five-year and early ten-year durability data confirm that TAVR valve function is maintained well in the medium term.

This evidence base is what has driven the transformation of TAVR from a last-resort procedure for the truly inoperable to a mainstream treatment option discussed for the majority of patients presenting with severe symptomatic aortic stenosis.

The First Step for Indian Patients and Families

For anyone navigating an aortic stenosis diagnosis—whether for themselves or for an older family member—the most important action is to seek evaluation at a center with a genuine TAVR program. Not every cardiologist is trained in structural heart disease. Not every hospital advertising cardiac services has the infrastructure, team, and case volume to deliver TAVR safely.

Dr. Raghu is a recognized TAVR/TAVI specialist in India, practicing in Hyderabad, with extensive structural heart disease experience and a Heart Team program that meets current international standards. Patients from across India and internationally consult his practice for TAVR evaluation, second opinions, and complex structural heart care.

The first step is a comprehensive evaluation — clinical assessment, echocardiography, and cardiac CT — that answers the question of whether TAVR, surgical valve replacement, or another approach is the right path for this specific patient. That evaluation, done well, changes outcomes.
