Stent in Heart: Solution for Heart blockage

Heart had always been the vital part of our life, without which we would not be able to sustain the veracities of body. Due to change in the lifestyle of the beings and stress issues, we encounter many problems that come across in our life. The cardiovascular disease, or the heart disease, affects the heart in much terrible manner. The disease includes coronary disease, heart arrhythmias, and heart failure.  After looking at the data, we see that cardiovascular disease has topped, accounting for 23 percent of all deaths. Putting stent in the heart has been one of the important aspects.


What are Stent?

Post many methods to cure heart disease the putting up of stents are being one of them. Stents are the small and expandable tubes that treat narrowed arteries in your body. The people who suffer from coronary heart disease which can be caused due to the buildup of plaque can use these stents.

These types are called heart stents; they can also be referred as cardiac stents or coronary stents. They are made up of metal mesh then they are placed in the arteries in a procedure called a percutaneous coronary intervention or the very common name, angioplasty. The stent in the heart is an important aspect of the process.


What is angioplasty?

When there is a narrowing in the blood vessels and the stent is used to correct the narrowing of the blood vessels than it is known as angioplasty. They will place the stent in the heart. There is no specific blood vessel that has to be treated by the stent but any blood vessels in the body can be treated by this method.

But a little bit of patience is needed while doing this method as more care needed during the procedure and after the operation has been done. The operation and the procedure use balloon catheter. The medications to help the patients to relax is given to them.


Why is the stent needed?

Stent in heart is given to the patient when the plaque blocks the blood vessel.  Plaque is dirt which has been created by excess cholesterol and other substance that gets attached to the walls of a vessel and creates blockage for the blood to flow. Stent is usually used in emergency mode when the coronary artery is blocked. Then the doctors place the stent in heart.

The doctor shall place a catheter in the blocked artery so that the blockage can be open. Then the stent will be placed to keep the vessel open. Besides using the stents for heart it can be also used for bile ducts, which are tubes that carry bile to and from digestive organs, bronchi and ureters since even they can get blocked or damaged just like blood vessels.


What is the risk involved and further side effects?

The risk is involved in any kind of surgical procedure. When the stent is inserted it gets the access to the arteries of the brain and heart. Here there can be an increased risk which can show adverse effects. The risk that would be involved is an:-

  •         There can be an allergic reaction to medications or dye used in the procedure
  •         There can be breathing problems due to anaesthesia or using a stent in the bronchi
  •         There can be bleeding and blockage of the artery
  •         There can be blood clotting in the artery
  •         There can be a risk of heart attack
  •         There can be an infection of the vessel
  •         If the stent is used in the ureters than there can be mild chances of kidney stones
  •         There can be chances of re-narrowing of the artery
  •         There can be rare side effects which include strokes and seizures
  •         If there is blood flow and blocked vessels then it can create serious and deadly consequences.
  •         The catheter can create damage to another blood vessels
  •         Arrhythmias which are irregular heartbeat can be caused due to this stent transplant.

 

Banning of bioresorbable stent:

These stents are biodegradable or naturally-dissolving. They serve the same purpose but are manufactured from a material that may dissolve or be absorbed in the body. The bioresorbable stents which have an increasing market in India have been banned in Europe and shall be only available in ‘clinical registry setting at select sites/institutions in Europe,’. This grave move has been taken after seeing the studies that the bioresorbable cardiac stents are not only worse than the existing drug-eluting stents but they are also having the shoddier outcome in some ways. Though this has the highest amounts of sell in India, the Abbott chairman of India has told that it has notified the Drug Controller General of India. This has been launched in India after clinical trials on 100 patients.
