Aortic Stenosis Treatment in Delhi – Cardiac Care by Dr. Dinesh Kumar Mittal

Aortic stenosis is one of the most common and serious heart valve conditions, affecting thousands of patients across India each year. It occurs when the aortic valve, which controls blood flow from the heart to the rest of the body, becomes narrowed and cannot open fully. This places considerable strain on the heart muscle and, if left untreated, can lead to heart failure, collapse, or sudden cardiac death.

For many patients, symptoms begin gradually, sometimes so gradually that the condition goes unrecognised for years. By the time breathlessness, chest pain, or fainting episodes appear, the disease may already be at a severe stage. Early diagnosis and specialist evaluation are essential.

Dr. Dinesh Kumar Mittal, Senior Director and Head of Cardiothoracic and Vascular Surgery at Fortis Hospital, Shalimar Bagh, Delhi, provides comprehensive assessment and treatment for aortic stenosis across all stages of severity. With over 25 years of experience, he brings specialist expertise to both surgical and catheter-based valve treatments, ensuring that every patient receives a treatment approach appropriate to their condition and overall health.

What Is Aortic Stenosis?

The aortic valve sits at the junction between the left ventricle (the heart’s main pumping chamber) and the aorta (the large artery that carries blood to the rest of the body). A healthy aortic valve opens and closes smoothly with every heartbeat, allowing blood to flow freely.

In aortic stenosis, the valve leaflets become thickened, stiff, or calcified over time. The valve opening narrows, and the heart must work significantly harder to push blood through the restricted passage. Over the years, this increased workload causes the heart muscle to thicken and eventually weaken.

Aortic stenosis is graded by severity:

Once symptoms develop in severe aortic stenosis, the outlook without treatment deteriorates significantly. Studies cited in international cardiology guidelines indicate a median survival of approximately two to three years after symptom onset without intervention. This makes timely assessment critically important.

What Are The Causes of Aortic Stenosis?

Aortic stenosis develops from several underlying causes, each more common in different age groups:

• Age-related calcification (most common in adults over 65): Over decades, calcium deposits accumulate on the aortic valve leaflets, making them progressively stiffer and less able to open fully. This is the most common cause among elderly patients in Delhi and across India.
• Bicuspid aortic valve (congenital): A normal aortic valve has three leaflets. In approximately 1-2% of the population, the valve forms with only two leaflets. This structural difference causes abnormal wear and tear, leading to stenosis decades earlier than age-related calcification, often in patients aged 40 to 60.
• Rheumatic heart disease: A significant cause in India, rheumatic fever (following untreated streptococcal throat infections) causes scarring and fusion of the valve leaflets. Rheumatic aortic stenosis often develops alongside disease in the mitral valve.
• Congenital aortic stenosis: In some children, the aortic valve is narrowed from birth. This is identified during childhood cardiac assessment and may require intervention in infancy, childhood, or early adulthood, depending on severity.

Symptoms of Aortic Stenosis

Aortic stenosis symptoms often appear late and signal advanced disease. Watch for chest pain, breathlessness, or fainting, and seek timely cardiac evaluation. One of the most important characteristics of aortic stenosis is that it may remain entirely silent for many years. The heart compensates for the narrowed valve for a long time before symptoms eventually emerge. When they do, it usually signals that the condition has reached a significant stage.

The three hallmark symptoms of severe aortic stenosis are:

• Chest pain or tightness (angina): Discomfort in the chest, particularly during physical activity or exertion, is often among the earliest symptoms. It occurs because the thickened heart muscle demands more oxygen than the narrowed circulation can deliver.
• Breathlessness: Difficulty breathing, initially on exertion and later at rest or when lying flat, reflects the heart’s inability to pump blood effectively against the narrowed valve.
• Fainting or near-fainting (syncope): Sudden loss of consciousness or lightheadedness, particularly during or after exertion, occurs because the heart cannot increase output adequately to meet demand.

Other aortic stenosis symptoms that may be present include:

• Fatigue and reduced exercise tolerance
• Heart palpitations or rapid heartbeat
• A heart murmur was detected during a routine examination
• Ankle swelling in advanced cases (a sign of heart failure)
• Dizziness

If you or a family member has noticed any of these symptoms, prompt evaluation by a cardiac specialist is important. A heart murmur detected during a routine check-up should always be investigated further, even in the absence of symptoms.

Diagnosis of Aortic Stenosis in Delhi

Diagnosis of aortic stenosis requires a combination of clinical assessment and targeted cardiac investigations. At Fortis Hospital, Shalimar Bagh, the diagnostic pathway includes:

• Echocardiogram (Echo): This is the primary diagnostic tool for aortic stenosis. An echocardiogram uses ultrasound to visualise the valve in real time, measure the degree of narrowing, assess the pressure gradient across the valve, calculate the valve area, and evaluate the heart muscle’s function and thickness. It is non-invasive, painless, and highly informative.
• Electrocardiogram (ECG): Identifies thickening of the heart muscle (left ventricular hypertrophy) and any associated rhythm abnormalities that may accompany aortic stenosis.
• Chest X-Ray: Can show changes in heart size and shape, and may reveal calcium deposits on the valve in advanced disease.
• CT Angiography / Cardiac: CT is used particularly when TAVR (transcatheter aortic valve replacement) is being considered. CT angiography provides detailed measurements of the aortic root, valve anatomy, and vascular access routes.
• Cardiac Catheterisation: In selected cases, catheterisation provides direct pressure measurements across the valve and a comprehensive assessment of the coronary arteries, which is important when surgery is being planned.
• Stress Testing: In patients with severe aortic stenosis but no clear symptoms, a supervised exercise stress test can unmask symptoms and help guide the timing of intervention.

Treatment Options for Aortic Stenosis in Delhi

Treatment for aortic stenosis depends on the severity of the narrowing, the presence and extent of symptoms, and the patient’s overall health and fitness for different types of intervention. There is currently no medication that reverses or halts valve narrowing itself, but the following treatment pathways are available:

1. Medications for Aortic Stenosis

Medications cannot repair or open a narrowed aortic valve, but they play an important role in managing symptoms and associated conditions while the overall clinical picture is monitored.

Commonly used medications include:

• Diuretics to reduce fluid retention and breathlessness
• Beta-blockers or rate-controlling agents are used when heart rate management is needed
• Blood pressure medications to reduce the workload on the heart
• Anticoagulants in patients with co-existing atrial fibrillation

Medical management is typically used in mild to moderate aortic stenosis, in patients awaiting intervention, or in those where intervention is not appropriate. It does not treat the underlying stenosis, and regular monitoring is essential to identify when the condition progresses.

2. Balloon Valvuloplasty

Balloon Valvuloplasty is a temporary option when immediate relief or stabilisation is needed. It is a catheter-based procedure in which a balloon is briefly inflated across the narrowed valve to widen the opening. In adults with calcific aortic stenosis, this is generally considered a temporary measure rather than a definitive treatment, as the valve tends to re-narrow over time. It may be used as a bridge intervention in patients who are unwell and need stabilisation before a definitive procedure, or in children and younger patients with non-calcified valve disease, where the results can be more durable.

3. Surgical Aortic Valve Replacement (SAVR)

Surgical aortic valve replacement (SAVR) is the established gold-standard treatment for aortic stenosis in patients fit for open-heart surgery. During the procedure, the diseased aortic valve is removed and replaced with either:

• A mechanical valve, made of durable materials, lasts a lifetime but requires lifelong anticoagulation (blood thinning) medication.
• A biological (tissue) valve, made from animal tissue (porcine or bovine), does not require long-term anticoagulation in most patients, but may need replacement after 15-20 years, depending on the patient’s age and activity.

The choice between valve types is made based on the patient’s age, lifestyle, other medical conditions, and preference following a thorough discussion.

SAVR is performed under general anaesthesia, typically takes 2-4 hours, and involves a hospital stay of 5-8 days. For suitable patients, it offers excellent long-term outcomes with well-established durability data. Dr. Dinesh Kumar Mittal has performed thousands of aortic valve replacements over his 25+ year career, including complex cases involving enlarged aortic roots, combined CABG and valve procedures, and reoperations.

4. TAVR / TAVI in Delhi (Transcatheter Aortic Valve Replacement)

Transcatheter Aortic Valve Replacement (TAVR), also known as TAVI (Transcatheter Aortic Valve Implantation), is a minimally invasive procedure that replaces the narrowed aortic valve without open-heart surgery. A replacement valve, mounted on a catheter, is delivered through a blood vessel (usually from the groin) and positioned precisely within the diseased native valve.

Who is a candidate for TAVR in Delhi?

• Elderly patients with severe aortic stenosis who are at high or intermediate risk for open surgery
• Patients with significant co-existing conditions (severe lung disease, kidney impairment, frailty) that make open surgery higher risk
• Patients who have previously had open heart surgery and require a re-do valve procedure
• Selected intermediate-risk patients for whom a heart team evaluation has confirmed TAVR as the appropriate approach

TAVR does not require a chest incision, avoids the use of a heart-lung machine in most cases, and is associated with a significantly shorter recovery period. Most patients are discharged within 2-4 days.

As part of North India’s Aortic Intervention Programme, Dr. Dinesh Kumar Mittal performs TAVR and related valve procedures using detailed CT planning and a team-based approach to select the right patients.

SAVR vs. TAVR: What Is the Difference?

Choosing between SAVR and TAVR depends on your age, risk profile, and recovery goals. This quick comparison explains the key differences to guide the most appropriate treatment decision.

The decision between SAVR and TAVR is not made based on a single factor. It involves a comprehensive review of imaging, valve anatomy, overall fitness, coronary artery disease, and patient preference.

What Is the Cost of Aortic Stenosis Treatment in Delhi?

The aortic stenosis treatment cost in Delhi ranges from Rs. 2,50,000 to Rs. 12,00,000 INR, depending on the recommended procedure, the chosen valve, and the overall clinical complexity of the case.

These are indicative market ranges for Delhi. A personalised written cost estimate based on your echocardiogram and clinical assessment is provided at consultation.

Factors that affect the final cost include:

• Type of procedure: SAVR vs. TAVR
• Type of valve selected: mechanical vs. biological; standard vs. TAVR device brand
• Complexity of the case: isolated valve replacement vs. combined with bypass or other procedures
• Duration of hospital stay and ICU care required
• Pre-operative investigations required
• Any co-existing conditions that require additional management

Most health insurance policies in India, including PM-JAY, CGHS, ESIC, and private health insurance, cover aortic valve replacement for documented clinical indications. Patients are advised to confirm cashless eligibility with their insurer before admission.
