Non-Coronary Intervention in Chennai

Non-Coronary Intervention in Chennai
Table of Contents

Non-coronary interventions increasingly emerge as the best treatment options for structural heart disease in patients with prohibitive or high surgical risk. Although the percutaneous interventional procedures involve the coronary arteries, the non-coronary transcatheter cardiac procedures are mainly encountered in the elderly people for its major developments.

Procedures of Non-Coronary Intervention

The procedures treated by the best interventional cardiologist in Chennai include the following:

Left Atrial Appendage Closure (LAA closure)

Left atrial appendage closure is a minimally invasive or surgical procedure to seal off the left atrial appendage (LAA). It is a small sac in the muscle wall of the left atrium (top left chamber of the heart). Removing it or closing it off reduces the risk of stroke and eliminate the need of intaking blood-thinning medication.

Who needs it? If you are prone to risk of developing blood clots in the left atrial appendage/ left atrium your healthcare provider may recommend this non-coronary intervention procedure to seal off the LAA. It is also an option for the patients who are unable to take blood-thinning medications to prevent blood clots which are caused by atrial fibrillation. 

Procedure:  During surgery for valve disease or coronary artery disease, the heart specialist in Chennai will remove the left atrial appendage and sew the closed area. They may staple it as this is a surgical left atrial appendage closure. In a minimally non-coronary intervention approach, they can use a catheter to insert a special device to block or close the left atrial appendage. These devices act as a plug in the left atrial appendage’s opening to the left atrium and keeps it from releasing clots.

Paravalvular Regurgitation Closure

Paravalvular leak (PVL) closure in the non-coronary intervention is a non-surgical treatment to repair heart valve leaks that may occur after valve replacement. The best interventional cardiologist in Chennai uses this treatment to repair leaks instead of performing any other surgery. Repeat surgery poses a higher risk to heart disease patients.

Who needs it?  A person who has had multiple surgeries to replace a valve can benefit from a leak closure. On the other hand, a person who is being treated for endocarditis, experience severe backward flow of blood, have severe calcification or calcium deposits on the ring around the valve annulus, have shortness of breath or dyspnoea, and shearing blood cells from the leakage or haemolytic anaemia can undergo this type of non-coronary intervention procedure.

Procedure: The patient will be given a local anaesthesia and medications before the procedure. Then the heart specialist in Chennai will insert a catheter into the femoral artery in the groin to the appropriate chamber of the heart. Then a closure device is placed to plug the leak using a special catheter. Unlike traditional surgery, this may not involve making an incision on the chest.

Peripheral Interventions – Lower Limb /Diabetic Foot Disease

Peripheral intervention is an accumulation of plaque (cholesterol and fats) in the arteries in the legs or arms. This makes it harder for the blood to carry nutrients and oxygen to the tissues in those areas. This long-term disease can be improved by eating less fat, exercising, and giving up tobacco products.

Who needs it? If anyone experiences burning or aching pain in the feet and toes especially at night while resting or lying flat, experience cool skin on the feet, have redness or color change in the skin, frequent infections and foot and toe sores that don’t heal.  The patient can approach a heart specialist in Chennai to get a prompt treatment else it would lead to complications like heart attack, stroke, renal artery disease or stenosis, etc. 

Procedure: There are various procedures that are treated if a patient experiences severe pain or limited mobility. Some of them include:

  • Balloon Angioplasty – The best interventional cardiologist in Chennai will pass a miniature balloon through the catheter into the arteries. When the balloon expands, the inside of the artery pushes against the plaque and opens up space in the interior of the artery.
  • Stents – In this non-coronary intervention procedure, tiny metal support coils are inserted into the arteries through catheters to expand against the inner blood vessel wall to support and hold it open.
  • Peripheral Artery Bypass Surgery – Similar to a heart bypass, the best non-coronary interventionist in Chennai uses a section of the healthy vein to create a bypass for blood flow in the leg artery around the blocked area. 
  • Atherectomy – It is the procedure where a catheter with a blade is inserted at the end to remove plaque build-up in the blood vessel.

Single Chamber Pacemaker

This type of pacemaker has a lead connecting the pulse generator to one chamber of the heart. This is used to control heartbeat pacing to connect the lead to the right ventricle Depending on the symptoms and the type of pacing, lead is connected to the right atrium to stimulate the pacing in that chamber.

Who needs it? A single chamber pacemaker with one lead is placed within the lower chamber/ ventricle of the heart. These pacemakers are to treat bradycardia and atrial fibrillation which is associated with bradycardia (abnormal slow heartbeat).

Dual Chamber Pacemaker

This type of pacemaker is used during the non-coronary interventions with two leads.  This device connects both the chambers on the right side of the heart, right ventricle and the right atrium. The heart specialist in Chennai programs the dual-chamber pacemaker for regulating the pace of contractions of both the chambers. It helps two chambers work together, by contracting and relaxing in the proper rhythm. The contractions will allow a proper flow of blood from the right atrium into the right ventricle.

Who needs it? A dual chamber pacemaker with two leads is placed on the right article and right ventricle of the heart. These pacemakers are similar to the function of the single chamber pacemaker and is used to treat atrial fibrillation and bradycardia which is associated with bradycardia in order to regulate the pace of contractions of both the chambers.

Endovascular Aortic Aneurysm Repair (TEVAR/EVAR)

This is a minimally invasive procedure which is used to manage abdominal aortic aneurysms. The largest artery to carry blood from your heart to other parts of the body is the aorta. For abdominal aortic aneurysms, EVAR uses sophisticated instruments and small punctures to repair bulges in blood vessels (aneurysms) located there.

Who needs it? The best interventional cardiologist in Chennai may consider EVAR if you have a smaller or larger aneurysm that’s growing quickly, do not qualify for an open-heart surgery with a large incision, and have healthy blood vessel tissue near the aneurysm.

Procedure:  The doctor used the femoral arteries, to access the abdominal aortic aneurysm in the belly for this type of non-coronary intervention procedure. Needles are inserted through underlying soft tissue and skin and into the femoral arteries. Then a catheter is inserted to guide through arteries to reach the aneurysm. When the catheter reaches the aneurysm, the stent graft is opened to expand and becomes a new, stable path for a proper blood flow. The graft’s wireframe forms a tight seal to keep the graft in place and prevents blood from entering your aneurysm. Then the catheter is removed.


To summarize, heart problems might make a patient stressed, anxious or scared. You can approach Dr. M. Kathiresan at MK Heart Clinic as this best non coronary intervention specialist can help you by understanding your situation and discuss the best treatment options to aid you in leading a healthy lifestyle.
