3. Percutaneous coronary intervention (PCI):
Balloon angioplasty
Stenting
Is a non-surgical procedure used to treat the stenotic (narrowed) coronary arteries of the heart found in coronary heart disease.
commonly known as coronary angioplasty or simply angioplasty

4. Balloon angioplasty
Rate of restnosis

1.Restenosis and immune response
2.Mechanical weakness
Mention the absorbable metal stent trials and …
3.It was an enhancement of prior types

6. Bio-Absorbable Drug-eluting stent
DREAMS is a balloon-expandable, paclitaxel-eluting scaffold on a rapid-exchange delivery system.

7. Bio-Absorbable Drug-eluting stent

8. Bio-Absorbable Drug-eluting stent
DREAMS was optimized to provide a longer scaffolding time than its predecessor and drug elution for inhibition of cell proliferation.
It is made of a magnesium alloy that is gradually absorbed. The absorption process is complete after 9–12 months.
The scaffold strut surface is coated with a 1μm matrix of the absorbable polymer carrier polylactic-coglycolic acid and the antiproliferative drug paclitaxel.

10. The weakness
Late Lumen loss due to plaque presuring the stent!

11. Heparin coating and getting rid of the paclitaxel
