Are stints placed in and around the heart dangerous?

Answer 1

Stents are usually placed to widen a vessel narrowed by cholesterol deposits. They have been widely used in vessels of the heart, as well as the carotid arteries and other areas of the body to improve blood flow, and are very successful. In October, a French study revealed that the stents posed a greater risk of stroke to the patient, than simply "cleaning out" the vessel, a procedure known as endartarectomy. Other studies have disputed these French findings, so studies in tne US are currently underway.

Answer 2

There are 23,500 angioplasties performed on patients with angina in the UK each year. Nine out of 10 operations are successful.
Fatty tissue - atheroma - responsible for narrowing arteries, is squashed, allowing blood to flow more easily.
A catheter is inserted into an artery under local anaesthetic in either the groin or the arm and guided using an X-ray screen to a coronary artery until its tip reaches the narrowed or blocked section.
A balloon mounted on the end of the catheter is then gently inflated to a diameter of about 3mm, flattening the atheroma.
A short tube of stainless steel mesh - a stent - may be inserted into the part of the artery to be widened to prevent re-narrowing after angioplasty.
Ultrasound and laser angioplasty can also be used but are rare.
Please see the web pages for more details on Angioplasty.

Answer 3

do you mean stents? they place them into clogged arteries when you have acs acute coronary syndrome or after a heart attack. it is a tiny mesh tube that after they go up through the artery it expands allowing blood to go through smoothly. the new stents have a coating of medication on them to help keep the mesh from closing again, it slowly releases over a little bit of time. this procedure has been a life saver and has helped many. after the stents or stent is placed the patient is given meds to ensure the non-clotting of blood. they are like anything man-made they can close up and they can fail but if you do what the doctor wants, change your life, smoking, drinking, eating well taking your meds you can live a long healthy life. hope that helped!

Answer 4

Stents are often life saving. My father had a quadruple bypass. Then two months later had to go back and have stents put in the artery they used to bypass the diseased coronary artery. Also, the stents are often pre-treated with medications to help prevent clotting.

Answer 5

No the stints are placed there to enhance the artery where is narrow..☺

Answer 6

I have had four friends who died after stint surgery.

Answer 7

its worth the risk you have blocked veins and they need to be opened
