Best Cardiologist for TAVR, TAVI and Angioplasty in Assam

Heart disease can become especially challenging when a patient has a complex coronary blockage, severe aortic valve narrowing or a high risk of open-heart surgery.

Patients and families searching for the best cardiologist in Assam may sometimes need the opinion of an experienced interventional cardiologist who regularly manages complex and high-risk heart conditions.

Dr. Dhamodaran K is a senior interventional cardiologist based in Chennai with extensive experience in advanced coronary interventions, complex angioplasty, TAVR/TAVI, structural heart procedures and cardiogenic shock management.

Patients from Guwahati, Dibrugarh, Tinsukia, Tezpur and other parts of Assam can contact his Chennai clinic to plan an appointment, review their medical reports and understand the most appropriate treatment options.

Hope for Patients with Limited Treatment Options

Some patients are told that their heart blockage is too complex for routine angioplasty. Others may be considered high-risk for bypass surgery or surgical valve replacement because of advanced age, poor heart function, kidney disease, lung disease or other medical conditions.

Advanced interventional cardiology may offer selected patients additional treatment possibilities.

Dr. Dhamodaran’s approach is focused on evaluating the patient’s complete medical condition, coronary anatomy, heart function and surgical risk before recommending treatment.

His areas of expertise include:

• Complex and multivessel coronary angioplasty
• Image-guided angioplasty using IVUS
• Calcified coronary blockage treatment
• Rotablation and orbital atherectomy
• Intravascular lithotripsy
• Laser angioplasty
• CHIP PCI for high-risk patients
• Impella-supported angioplasty
• Primary angioplasty during heart attacks
• TAVR and TAVI for severe aortic stenosis
• Structural heart interventions
• Cardiogenic shock management
• Mechanical circulatory support
• Peripheral and endovascular interventions

The objective is not simply to perform a procedure. It is to identify a safe, evidence-based and personalised treatment strategy for each patient.

Meet Dr. Dhamodaran K

Dr. Dhamodaran K is an experienced interventional cardiologist practising in Chennai.

He completed his DM in Cardiology from Madras Medical College and Research Institute under Dr. MGR Medical University. His advanced interventional cardiology training includes a postdoctoral Fellowship of the National Board from Escorts Heart Institute, Delhi.

His professional qualifications and fellowships include:

• DM in Cardiology
• Fellowship of the National Board in Interventional Cardiology
• Fellow of the European Society of Cardiology
• Fellow of the Society for Cardiovascular Angiography and Interventions, USA

With more than 24 years of clinical and interventional experience, he has treated patients with a wide range of coronary artery, structural heart, valve and vascular conditions.

As a high-volume interventional cardiologist, he has performed more than 25,000 cardiac catheterisation procedures, including diagnostic angiograms, coronary interventions and advanced catheter-based heart treatments.

Why Patients from Assam Consult Dr. Dhamodaran

A patient searching online for the best heart specialist in Assam may be looking for more than a routine cardiac consultation.

The patient may have:

• A complex or heavily calcified heart blockage
• Multiple blocked coronary arteries
• A previously failed angioplasty
• Recurrent narrowing inside an older stent
• A chronic total occlusion or 100% blockage
• Poor heart-pumping function
• Severe aortic stenosis
• High risk for open-heart surgery
• A previous recommendation for bypass surgery
• Kidney, lung or other medical conditions that increase procedural risk

Dr. Dhamodaran evaluates such patients to determine whether advanced catheter-based treatment may be appropriate.

Not every patient will require angioplasty or TAVR. The final treatment decision depends on symptoms, test results, heart anatomy, age, associated medical conditions and the expected risks and benefits of each option.

TAVR and TAVI Treatment for Patients from Assam

TAVR and TAVI refer to the same type of procedure.

• TAVR: Transcatheter Aortic Valve Replacement
• TAVI: Transcatheter Aortic Valve Implantation

The procedure is used to replace a severely narrowed aortic valve without performing conventional open-heart valve replacement surgery.

During TAVR, a replacement valve is delivered to the heart through a catheter, commonly through an artery in the leg. The new valve is positioned inside the diseased aortic valve to restore better blood flow.

TAVR is an established treatment for appropriately selected patients with severe, symptomatic aortic stenosis. Patient suitability is determined after detailed assessment by a multidisciplinary heart team.

Who May Need a TAVR Evaluation?

Patients diagnosed with severe aortic stenosis may experience:

• Breathlessness during walking or routine activity
• Chest pain or pressure
• Unusual tiredness
• Dizziness
• Fainting episodes
• Reduced ability to exercise
• Swelling of the feet
• Repeated hospitalisation for heart failure

Aortic stenosis causes narrowing of the heart’s aortic valve, restricting blood flow from the heart to the rest of the body. Severe disease requires timely specialist evaluation because it can lead to serious complications if left untreated.

Patients searching for a TAVR specialist in Assam or TAVI treatment in Assam may contact Dr. Dhamodaran’s clinic in Chennai for an advanced evaluation and treatment opinion.

Tests Commonly Reviewed Before TAVR

A TAVR evaluation may include a review of:

• Echocardiogram
• CT aortic angiogram
• Coronary angiogram
• ECG
• Kidney function tests
• Lung function
• Current medications
• Previous cardiac procedures
• Surgical-risk assessment
• Frailty and mobility assessment

The treatment plan is personalised after reviewing the patient’s valve anatomy, general health and expected benefits from the procedure.

Advanced Angioplasty for Complex Heart Blockages

Coronary angioplasty is a catheter-based procedure used to open narrowed or blocked coronary arteries and improve blood flow to the heart muscle.

A small balloon is advanced to the blockage and inflated. In most cases, a stent is then placed to help keep the artery open.

Routine blockages can often be managed using standard angioplasty techniques. However, some blockages are more difficult because they are:

• Severely calcified
• Very long
• Located at a major branching point
• Affecting the left main coronary artery
• Present in multiple vessels
• Completely blocked
• Located inside an older stent
• Associated with poor heart function
• Present in patients with high surgical risk

These cases may require an experienced angioplasty specialist and access to advanced imaging, plaque-modification technology and mechanical heart support.

Technologies Used in Complex Angioplasty

Depending on the patient’s condition and coronary anatomy, Dr. Dhamodaran may use advanced interventional technologies such as:

Intravascular Ultrasound

Intravascular ultrasound, or IVUS, provides detailed images from inside the coronary artery.

It can help assess:

• Blockage severity
• Artery size
• Plaque distribution
• Calcium burden
• Stent expansion
• Stent positioning

IVUS-guided treatment can be particularly valuable during complex, left-main and multivessel angioplasty.

Rotablation

Rotablation uses a specialised device to modify hard calcium inside a coronary artery.

It may be considered when severe calcification prevents a balloon or stent from expanding properly.

Orbital Atherectomy

Orbital atherectomy is another plaque-modification technique that may be used in selected calcified coronary blockages.

Intravascular Lithotripsy

Intravascular lithotripsy uses pressure waves to fracture calcium within the artery wall. This can help the artery expand and allow better stent placement.

Laser Angioplasty

Laser angioplasty may be considered in selected difficult cases, including certain resistant blockages or narrowing inside a previously placed stent.

Cutting and Scoring Balloons

Specialised balloons may be used to modify resistant plaque and prepare the artery for stent implantation.

Impella-Supported Angioplasty

Patients with poor heart function or complex coronary anatomy may sometimes require temporary mechanical circulatory support during high-risk angioplasty.

Impella can help support blood circulation while the coronary intervention is being performed in carefully selected patients.

CHIP PCI for High-Risk Heart Patients

CHIP PCI stands for Complex Higher-Risk and Indicated Patient Percutaneous Coronary Intervention.

It generally refers to complex angioplasty performed in patients who have challenging coronary anatomy, serious medical conditions or a high risk of complications.

CHIP PCI may be evaluated for patients with:

• Poor left ventricular function
• Left-main coronary artery disease
• Multiple coronary blockages
• Severe coronary calcification
• Previous bypass surgery
• Chronic total occlusion
• High risk for open-heart surgery
• Other major medical conditions

The procedure may involve a combination of intravascular imaging, calcium-modification devices and mechanical circulatory support.

Every patient requires individual evaluation. A complex blockage does not automatically mean that angioplasty is the correct treatment. Some patients may benefit more from medication, bypass surgery or another treatment strategy.

Heart Attack and Cardiogenic Shock Treatment

A heart attack can occur when a coronary artery becomes suddenly blocked, interrupting blood supply to part of the heart muscle.

Emergency angioplasty may be performed to reopen the artery and restore blood flow.

Some patients develop cardiogenic shock, in which the heart cannot pump enough blood to support the body’s organs. These patients may require intensive cardiac care, emergency intervention and temporary mechanical circulatory support.

Dr. Dhamodaran’s expertise includes:

• Primary PCI for acute myocardial infarction
• Cardiogenic shock interventions
• Mechanical circulatory support
• Impella-assisted procedures
• ECMO-supported cardiac care
• Heart recovery programmes

Patients experiencing current chest pain, severe breathlessness, sweating, fainting or symptoms of a possible heart attack should seek immediate emergency treatment at the nearest hospital in Assam. They should not delay emergency care to travel to another state.

No. Dr. Dhamodaran’s consultation locations are in Chennai. This page is intended for patients from Assam who are looking for an advanced interventional cardiology opinion or planning treatment in Chennai.

Are TAVI and TAVR different procedures?

No. TAVI and TAVR are commonly used names for the same catheter-based aortic valve replacement procedure.

Who may be suitable for TAVR?

TAVR may be considered for selected patients with severe aortic stenosis. Suitability depends on symptoms, valve anatomy, age, general health, surgical risk and assessment by the treating heart team.

Is TAVR suitable only for high-risk patients?

TAVR was initially used mainly for patients at high surgical risk. It is now an established option across different surgical-risk categories in appropriately selected patients. The choice between TAVR and surgical valve replacement must be individualised.

Can a 100% heart blockage be treated with angioplasty?

Some chronic total occlusions may be treated through advanced angioplasty, but not every 100% blockage requires or is suitable for intervention. The decision depends on symptoms, heart function, viability of the heart muscle, blockage anatomy and alternative treatment options.

Can a heavily calcified blockage be treated without bypass surgery?

Selected calcified blockages may be treated using advanced techniques such as rotablation, orbital atherectomy or intravascular lithotripsy. However, bypass surgery may remain the preferred option for some patients.

Should an Assam patient travel during a heart attack?

No. A suspected heart attack is a medical emergency. The patient should immediately visit the nearest emergency hospital in Assam. Travel to Chennai should only be planned after the patient is medically stable and after consultation with the treating doctors.
