Effect of PSP and other Elements of Technique on 3 Year Outcomes Among Metallic Everolimus-Eluting Stent -Treated Patients in the ABSORB Trials • 1223 patients and 1284 lesions treated with EES • ABSORB II, ABSORB III, ABSORB China and ABSORB Japan trials • 3-year TLF and stent thrombosis (ST) were correlated with PSP PSP: Pre-dilatation, appropriate vessel sizing and post-dilatation All 3 elements performed in only 2.7% patients

5.8% 1400 Patients MACE: • Cardiac Death 2.9% • Target Lesion MI • TLR 1 year * Hong S-J et al. JAMA 2015; (20): 2155-2163

• 7 RCTs • 3192 Patients • Mean Lesion 32 mm Favors Angiography-guidance Favors IVUS-guidance Elgendy IY et al. Circulation: Cardiovasc Interventions 2016; 9:e003700

IVUS-guided PCI was associated with: 1. Significantly larger post-intervention MLD 2. Greater reduction in the diameter stenosis 3. Reduction in the risk of MACE (NNT=26) * 4. Borderline lower risk of stent thrombosis and cardiovascular mortality * primarily due to a reduction in ischemia or clinically driven TLR (NNT=40) at a mean follow-up of 15 months. Elgendy IY et al. Circulation: Cardiovasc Interventions 2016; 9:e003700

• Prospective, multicenter, nonrandomized all-comers study • 8582 consecutive patients • 11 US and German Sites • Propensity-adjusted multivariable analysis • Impact of IVUS guidance on 2-year outcomes Maehara A et al. Circ Cardiovasc Interv. 2018;11:e006243.

Expected Impact of Intracoronary Imaging for PCI Guidance Burzotta, F and Trani C. Circulation: Cardiovascular Interventions. 2018;11

2011 ACCF/AHA/SCAI Guidelines for PCI I IIa IIb III IVUS is reasonable for the assessment of angiographically indeterminant LM CAD. IVUS and coronary angiography are reasonable 4 to 6 weeks and 1 year after cardiac transplantation to I IIa IIb III exclude donor CAD, detect rapidly progressive cardiac allograft vasculopathy, and provide prognostic information. Levine GN et al. JACC 2011; 58(24): E44-122.

2011 ACCF/AHA/SCAI Guidelines for PCI I IIa IIb III IVUS is reasonable to determine the mechanism of stent restenosis . IVUS may be reasonable for the assessment of I IIa IIb III non-LM coronary arteries with angiographically intermediate coronary stenoses (50% - 70%) diameter stenosis. Levine GN et al. JACC 2011; 58(24): E44-122.

2011 ACCF/AHA/SCAI Guidelines for PCI I IIa IIb III IVUS may be considered for guidance of coronary stent implantation, particularly in cases of LM coronary artery stenting I IIa IIb III IVUS may be reasonable to determine the mechanism of stent thrombosis. Levine GN et al. JACC 2011; 58(24): E44-122.

When to Use Intracoronary Imaging? a) Large territory at risk if there is stent failure OR b) Scenarios associated with high risk of stent failure Anatomical/Procedural Factors: Patient Factors: • Diabetes Mellitus • Aorto-ostial/Left Main disease • End Stage Renal Disease • Bifurcation stenting • Co-morbidity necessitating the use of BMS • Prior stent failure due to ISR or IST • Long Lesions (> 28 mm) Calcium Management • Lesion Assessment - Do I need to use Atherectomy? - Should I avoid Atherectomy? • Stent Optimization

How to Increase Intracoronary Imaging? 1. Improve Physician Education 2. Lack of Image Interpretation Skill is a barrier 3. Update Guideline Recommendations 4. Intracoronary Imaging should be a Quality Metric 5. Improve reimbursement
