Long-term Outcome of Incomplete Revascularization After PCI SCAAR: 23,342 patients with multivessel disease undergoing PCI (65% had incomplete revascularization) ) in Sweden, 2006-2010. Incomplete revascularization tied to higher rates of death, MI, or repeat revascularization (33.4% vs 15.3%) and individual components Elevated risks of composite endpoint, death, and composite of death/mi remained after propensity-score adjustment Greater risk of death, MI, or repeat revascularization was consistent regardless of type of presentation Conclusion: Incomplete vs complete revascularization after PCI is associated with poorer 1-year outcomes. Hambraeus K, et al. J Am Coll Cardiol Intv. 2016;9:207-215.
Incomplete Revascularization SYNTAX Revascularization Index (SRI=bSS-rSS/bSS) Concl: 1 yr adverse clinical outcomes were inversely proportional to SRI (SRI < 80% had best prognostic accuracy) Genereux P et al Eurointervention 2014
PCI Revascularization for CAD My Current Practice Treat only Culprit lesion at Index PCI In MVD pts, after Rx of Culprit lesion, treat nonculprit lesions according to Sx or evidence of ischemia (preferably by non-invasive rather than invasive FFR) Staged PCI ischemic non-culprit lesions to achieve complete revascularization CR or at least to SRI < 80%
1 stent to 3 Vessel Disease (NOT 3 stents to 1VD) Pre-PCI Post-PCI FFR 0.92 1 DES3.0x15 to LAD
3yr later : 3 stents to treat 1 RCA lesion! Symptomatic, repeat angio. showed patent LAD stent. Progression of RCA lesion found & PCI performed without prior FFR using 2 overlapping stents (3.0x 18 & 3.0x15), and a third proximal stent (3.0x8) to teat Amplatz guide dissection. Real-Life (Self) evidence to support CR by Staged PCI!

China s PCI Challenge 2016 Non-inferiority Trial of Eastern PCI vs Western CABG Hypothesis: Eastern Staged CR PCI is non-inferior to Western CABG CR for complex CAD Inclusion: Complex CAD pts (by SS/FSS>33) Therapy: Best-practice Functional PCI in selected PCI centers in the East vs Inclusion: Complex CAD pts (by SS/FSS>33) Therapy: Best-practice CABG in selected centers in the West Primary End-point: In-hospital, 30d & annual all-cause mortality & MACCE for 5 yr
Synergy of East/West Coronary Revasc 東西方 各取其長 ; 和諧共進 Work in the Hexagon to achieve Equivalence *Working at the same Level
Conclusion : Complex lesions (SYNTAX>33) are the remaining indication for CABG surgery Sequential staged PCI to achieve adequate ( > 80%) complete CR that is superior to Incomplete CR Complete CR of complex lesions (SYNTAX >33) by PCI is technically feasible and practiced routinely in the East Evidence of non-inferiority of Eastern PCI CR compared to Western CABG is eagerly awaited ( 加油 )!
