1 Intracoronary Imaging For Complex PCI A Pichard, L Satler, Ron Waksman, I Ben-Dor, W Suddath, N Bernardo, D Harrington. Medstar Washington Hospital Center Washington, DC

2 Conflict of Interest None for this presentation

3 Accepted Basic principles Angiography (QCA) is no longer the Gold Standard for lesion assessment. Complex lesions often inadequately defined by Angio. IC Imaging (IVUS/OCT) leads to optimal PCI less complications, less stent thrombosis and improved outcomes. IVUS, OCT, NIRS, HD IVUS, CT all useful.

4 Angiography is no Longer the Gold Standard to Indicate Revascularization in Coronary Lesions. 1. Angiography is adequate for: a. mild lesions (20-40%). b. severe lesions (>80-90%). 2. Angiography is not adequate for intermediate lesions: 50-80%.

5 881 Lesions with IVUS/FFR. Han et al. EuroIntervention. 2012;8:N74.

6 Angio is Most Inaccurate in LM. Olivier Muller. ESC 2011 FFR 0.89 FFR 0.68

7 ADAPT-DES: IVUS Changed the Procedure 74% of the Time Witzenbichler et al. Circ 2014;129:463-70

8 OCT Impacts Decision Making in PCI W Wijns et al. EHJ 2015;36: patients with stable/unstable AP Pre PCI OCT changed PCI strategy in 55% of patients. Post PCI OCT led to further optimization in 25% of patients. Less periprocedural MI in OCT patients

9 IVUS Use and MACE (Definite/Probable ST, Cardiac Death, MI) Event Rate (n) IVUS vs Angio HR [95%CI] P-Value All 4.9% (158) vs 7.5% (373) 0.65 [0.54, 0.78] < STEMI 3.7% (15) vs 6.4% (24) 0.56 [0.29, 1.07] 0.07 NSTEMI/UA 6.1% (82) vs 8.8% (184) 0.68 [0.52, 0.88] Stable CAD 4.2% (61) vs 6.5% (165) 0.63 [0.47, 0.85] Favors IVUS Use Favors Angio Use ADAPT-DES Clinicaltrials.gov NCT

30 Randomized Trials of PCI with/without IVUS. Metanalysis Elgendy et al. Circ Cardiovasc Interv. 2016;9:e patients MACE

31 Conclusion Routine use of Intra Coronary Imaging results in: Safer, faster, optimal procedure. Prevents complications. Improves outcomes: less ST, less restenosis, less MACE. No stress for the operator: no unknowns to deal with!

32 Reimbursement Dilemma FFR and IVUS usually not reimbursed. If PCI deferred: benefit for the patient, but the cost may not be reimbursed to the Hospital.
