title: Retrospective Multicenter Comparison of S.M.A.R.T. CONTROL and MISAGO Stents in Treatment of Femoropopliteal Lesions.
abstract: OBJECTIVE
  To compare primary patency between MISAGO (Terumo Corporation, Tokyo, Japan) and S.M.A.R.T. CONTROL (Cordis Corporation, Miami Lakes, Florida), second-generation and first-generation nitinol stents, in femoropopliteal lesions.
  
  
  METHODS
  This multicenter, retrospective study included 240 cases with MISAGO stent implantation and 1,265 cases with S.M.A.R.T. stent implantation. The S.M.A.R.T. group had more Trans-Atlantic Inter-Society of Consensus (TASC) II class C/D lesions (53% vs 41%, P = .001) and smaller reference vessel diameter (RVD) (5.3 mm ± 0.9 vs 5.5 mm ± 0.9, P < .001).
  
  
  RESULTS
  Kaplan-Meier estimates of 2-year primary patency after S.M.A.R.T. and MISAGO stent implantation were 67% and 55% (P = .007). Interaction analysis revealed that TASC II classification and RVD had a significant influence on the association of MISAGO versus S.M.A.R.T. stents with the outcome. The study population was stratified according to TASC II classification and RVD, and MISAGO and S.M.A.R.T. stents were compared after propensity score matching. There was no significant difference in 2-year patency between the 2 stents in the subgroup with TASC II class A/B and RVD ≥ 5 mm (S.M.A.R.T. 82% ± 4 vs MISAGO 74% ± 5, P = .480). MISAGO stents had lower primary patency than S.M.A.R.T. stents in cases with TASC II class C/D or RVD < 5 mm (S.M.A.R.T. 62% ± 6 vs MISAGO 25% ± 6, P = .015).
  
  
  CONCLUSIONS
  S.M.A.R.T. and MISAGO stents had similar patency in simple lesions, but MISAGO stents had lower patency than S.M.A.R.T. stents in more complex lesions.
