Stent Thrombosis, although rare (occur in <1%
patients within the first year), is one of the most
serious complications following stent placement.
More than 80% of patients who experience
stent thrombosis present with acute MI, and
30-day mortality rates in patients with stent
thrombosis range from 10% to 25%.
As a result, prevention and treatment of
this complication are of utmost importance.

High residual 𝙥𝙡𝙖𝙩𝙚𝙡𝙚𝙩 𝙧𝙚𝙖𝙘𝙩𝙞𝙫𝙞𝙩𝙮 after treatment,

𝙇𝙚𝙨𝙞𝙤𝙣 𝙛𝙖𝙘𝙩𝙤𝙧𝙨 that increase risk of thrombosis include diffuse disease with long stented segments, small vessels, bifurcation disease, and significant inflow or outflow lesions proximal or distal to the stent.
𝙋𝙧𝙤𝙘𝙚𝙙𝙪𝙧𝙖𝙡 𝙛𝙖𝙘𝙩𝙤𝙧𝙨 :

▫️inadequate stent expansion and/or apposition,
▫️Stent type used (i.e., BMS or DES),
▫️Excessive stent overlap, and
▫️Edge dissections limiting inflow or outflow.
▫️Strut fracture linked to +Risk of thrombosis.
The thicker struts of earlier generation BMS and DES systems have been associated with increased risk of stent thrombosis, and this may have implications in the thrombosis risk of first-generation bioabsorbable scaffolds.
In addition, the polymers used in certain first-generation DES systems may be inherently throm-bogenic and/or prone to mechanical deformation after implantation, serving as a nidus for thombus formation.

==============================
The inflated balloon exerts pressure against the plaque
and the arterial wall, causing fracturing and splitting.
• Concentric (round or circumferential) lesions
fracture and split at the thinnest and weakest points.
• Eccentric lesions split at the junction of plaque
and the normal arterial wall.
• Dissection or separation of the plaque from
vessel wall releases the restraining effect
caused by the lesion and results in a larger lumen.
👉This is the major mechanism of balloon angioplasty.
2️⃣. 𝙇𝙤𝙨𝙨 𝙤𝙛 𝙀𝙡𝙖𝙨𝙩𝙞𝙘 𝙍𝙚𝙘𝙤𝙞𝙡
===============
• Balloon dilatation causes stretching and thinning
of the medial musculature of the vessel wall.
• Stretching causes the vessel wall to temporarily
lose its elastic (recoil) properties.
• The degree of elastic recoil is affected by
the balloon-to-artery size ratio.
• Almost all vessels have some elastic recoil and,
over time, will recoil, which is a contributing
mechanism to restenosis.
• The major initial benefit of stenting is elimination
of elastic recoil, which maintains a large lumen over time.
3️⃣. 𝙍𝙚𝙙𝙞𝙨𝙩𝙧𝙞𝙗𝙪𝙩𝙞𝙤𝙣 & 𝘾𝙤𝙢𝙥𝙧𝙚𝙨𝙨𝙞𝙤𝙣 𝙤𝙛 𝙋𝙡𝙖𝙦𝙪𝙚
=============================
• During angioplasty, balloon pressure causes
denudation of vessel wall lining (endothelial)
cells and extrusion or pushing out of plaque components.
• There may be some extrusion longitudinally of
the softer lipid material, but this effect accounts
for a very small part of the overall effect.

• Angiographic success without in-hospital
major clinical complications
(e.g., death, m [MI], emergency CABG).
• MI is often defined as the development of
Q-waves in addition to elevation of troponins
three times the upper limits of normal value.
• Cardiac troponin T and I as measurements of
myocardial necrosis are more sensitive and
specific than CK-MB.
• Enzyme elevations in the absence of new
Q-waves is counted as MI, peri-procedural.
• There is no consensus on what level of troponin
alone is clinically important enough to change
major management following the interventional procedure.

============
• A clinically successful PCI is an anatomic and
procedural success with relief of signs and/or
symptoms of myocardial ischemia after recovery
from the procedure.
• The long-term clinical success requires that
patient has continued relief of signs ,symptoms
of myocardial ischemia for more than 6 months.
• Restenosis is the principal cause of lack of
long-term clinical success when short-term
clinical success has been achieved.
