Interventional Cardiology


Interventional Cardiology is an advanced sub-speciality of cardiology. It is recommended in case of structural diseases of heart. Interventional cardiology is a surgical procedure with minimal invasion and is quite effective in treating many cardiovascular and congenital heart diseases. It is quite effective in removing any blockage in the arteries. The procedure is done through a tiny instrument called catheter which is inserted in the body through a very small incision in to a major blood vessel.

The procedures which are conducted under Interventional Cardiology are Angioplasty and Stenting, at Aakash Healthcare Super Speciality Hospital, we have fully-equipped and manned department to conduct these procedures successfully:

What is Angioplasty?

Angioplasty is a surgical procedure which is conducted to remove the obstruction probably blood clots or any calcification in arteries or veins connected to heart. It is a minimal invasive procedure where a very small incision is made through which a catheter is inserted. The catheter also carries a deflated balloon through the narrowed vessel once the surgeon reaches the obstruction, the balloon is inflated in order to make space and the obstructed blood flow is released removing the obstruction and releasing stress on the artery and the heart. The procedure is also referred to as Balloon Angioplasty because of the use of balloon in removing the blockage in the arteries.

What are different procedures done under Angioplasty?

Angioplasty treats different cardiovascular disorders and is quite effective in warding off any threat to heart. The various procedures we conduct at Aakash Healthcare Super Speciality Hospital Hospital:

Carotid Angioplasty: The angioplasty is conducted to treat stenosis which is a condition where plaque is formed in the artery resulting in blood clots.

Renal Artery Angioplasty: Renal artery is responsible for supplying blood to kidneys. Any obstruction in this artery may lead to malfunctioning of kidneys or hypertension. Angioplasty procedure is quite effective and safe while removing any plaque formation from this area.

Venous Angioplasty: During the procedure, the surgeon removes blockage from veins which may have been compressed resulting in pain and discomfort to the patient.

Angioplasty with Rotablator: Sometimes the blockages in arteries are solid or calcified and it is not possible to remove through ballooning process. In that case, a tiny drill machine or a rotablator is administered into the body along with the catheter to remove any solid blockage.

How does a surgeon conduct Angioplasty?

The procedure is done under local anaesthesia. The surgeon will make a very small cut through the skin and will insert a catheter which also has a small camera attached to it, giving a clear view of inside the body. The surgeon, with the help of the internal view, will guide the catheter to the area which needs to be treated. After reaching the blockage, the wire (which also has a deflated balloon attached to it) is passed through the vein and the balloon is inflated using water mixed with contrast dye. Once the obstruction is removed the catheters are removed.

When can I go home after Angioplasty?

Patients can go home the following day after being under observation for some time.

What is Stenting?

Stenting is the procedure of placing a stent permanently into the obstructed vein or artery to further avert the threat of any blockage. The procedure is similar to ballooning and is administered along with that.

What is a stent?

A stent is a tube like structure which may be made of steel, cobalt-chromium alloy or nitinol. It helps in maintaining the blood circulation after the removal of blockage and is quite effective in treating coronary and peripheral artery disease.

How does a surgeon places a stent in the artery or a vein?

The stent is administered in the affected artery or vein along with the catheter and deflated balloon. Once the catheter reaches the affected area, the balloon is inflated giving space for stent to crimp around the vein permanently. After that, the catheter and the balloon are removed while the stent remains. The surgeon then closes the access to the vascular system.

What are the risks, I may face while undergoing angioplasty?

Angioplasty is one of the effective procedures to prevent the heart from any further deterioration. However, like any other surgery, it too has its risks like:

  • Further blood clotting or hematoma
  • Debris of blockage getting washed up in the blood stream
  • Ruptured artery due to over inflation of balloon
