In this video, we explain Angioplasty and Stenting from Chapter 11: Human Circulatory System – F.Sc. 1st Year Biology (Punjab Textbook, New Syllabus 2025, PTB Book 2025, National Curriculum of Pakistan).

???? Angioplasty is a medical procedure used to open blocked or narrowed coronary arteries using a catheter, balloon, and x-ray guidance. The balloon dilates the artery, restoring blood flow.
???? Stenting involves placing a small stainless steel mesh tube (stent) inside the artery to keep it open permanently. This prevents re-blockage and supports the artery walls.

✨ Topics covered in this lecture:
✔ What is angioplasty?
✔ Step-by-step angioplasty procedure
✔ Balloon catheter role
✔ Use of dye for dilatation confirmation
✔ What is stenting?
✔ Procedure of stent placement
✔ Importance of stents in heart disease treatment

???? This lecture is based on the Punjab Textbook Class 11 Biology – New PTB Book 2025, following the National Curriculum of Pakistan 2025.
