Recently, Delhi High Court asked the Central government to respond to a plea seeking sale and marketing of coronary stents in the country only after submission of adequate supporting clinical studies.

 

What is a Stent?

  • A stent is a tiny, expandable metal mesh coil. It is put into the newly opened area of the artery to help keep the artery from narrowing or closing again.
  • This revascularization procedure is termed as a percutaneous coronary intervention (PCI) or coronary angioplasty with stent placement.
  • Coronary stents are now used in nearly all angioplasty procedures.
  • Most stents are coated with medicine to prevent scar tissue from forming inside the stent. These stents are called drug-eluting stents (DES).
  • Compared to coronary artery bypass surgery, which is much more invasive, people who get stents have less discomfort and a shorter recovery time.

 

What is ‘Angioplasty’?

  • It is a procedure used to open blocked coronary arteries caused by coronary artery disease.
  • It restores blood flow to the heart muscle without open-heart surgery.
  • Angioplasty can be done in an emergency setting such as a heart attack. Or it can be done as elective surgery if your healthcare provider strongly suspects you have heart disease.
  • Performed with local anaesthesia and mild sedation, angioplasty involves no major incisions and usually takes about an hour.
