Slide 2: Objectives
- Review pathophysiological mechanisms driving post-dilation complications.
- Discuss mechanical, pharmacological, and emerging strategies to mitigate risks.
- Highlight clinical evidence and future directions.
Slide 3: Background: Balloon Angioplasty & Key Challenges
Brief Overview:
- Immediate lumen gain via plaque compression/fracture.
- Complications: Acute recoil, dissection, thrombosis, restenosis (30–50% historically), distal embolization.
Visual:
Timeline of complications (acute vs. chronic).
Slide 4: Pathophysiological Mechanisms (Flowchart)
Mechanical Injury → Endothelial damage → Platelet activation → Inflammation → Neointimal hyperplasia.
Key Drivers:
- Thrombosis (exposed collagen, TF release).
- Smooth muscle cell (SMC) proliferation.
- Inflammatory cytokines (IL-6, TNF-α).
Visual:
Simplified flowchart with icons (platelets, SMCs, cytokines).
Slide 5: Mechanical Strategies to Reduce Complications
Stent Implantation:
- Bare-Metal Stents (BMS): Prevent recoil/dissection but risk restenosis.
- Drug-Eluting Stents (DES): Sirolimus/paclitaxel inhibit SMC proliferation (restenosis <10%).
Intravascular Imaging Guidance:
IVUS/OCT to optimize stent deployment and assess plaque morphology.
Embolic Protection Devices:
Filters/balloons to capture debris in carotid/renal interventions.
Visual:
DES vs. BMS restenosis rates (bar graph).
Slide 6: Pharmacological Interventions
Antiplatelet Therapy:
- DAPT: Aspirin + P2Y12 inhibitors (clopidogrel, ticagrelor) for 6–12 months (reduces stent thrombosis).
- GP IIb/IIIa Inhibitors (e.g., abciximab): High-risk PCI cases.
- Anticoagulants: Heparin/bivalirudin during procedure.
Statins:
High-intensity (atorvastatin/rosuvastatin) stabilize plaques via LDL reduction/anti-inflammatory effects.
Novel Agents:
- Colchicine: Anti-inflammatory (COLCOT trial: ↓MI/stroke post-PCI).
- SGLT2 Inhibitors: Cardio-renal protection in diabetic patients.
Visual:
Drug mechanisms (icons + short text).
Slide 7: Emerging Therapies
Drug-Coated Balloons (DCB):
Paclitaxel delivery without permanent implants (ideal for small vessels).
Bioresorbable Scaffolds:
Temporary stents (e.g., Abbott's Absorb) reduce long-term inflammation.
Gene Therapy:
Local delivery of siRNA (e.g., inclisiran) to target pro-restenotic genes.
Nanoparticle Drug Delivery:
Targeted anti-inflammatory/anti-proliferative agents.
Visual:
DCB vs. DES mechanism comparison.
Slide 8: Clinical Evidence & Case Studies
CASE 1:
DES + DAPT reduced restenosis from 35% to 5% in diabetic patients (LEADERS FREE trial).
CASE 2:
Colchicine post-PCI ↓ recurrent ischemia by 23% (LoDoCo2 PCI substudy).
Meta-Analysis:
DCB vs. DES in coronary in-stent restenosis (non-inferior outcomes).
Visual:
Key trial data snapshots.
Slide 9: Future Directions
Precision Medicine:
Genetic profiling to guide antiplatelet therapy (CYP2C19 testing for clopidogrel response).
AI-Driven Imaging:
Predictive algorithms for plaque vulnerability.
Bioengineered Stents:
Endothelial progenitor cell capture technology.
Visual:
