UNASSIGNED: The aim of the present study was to determine the long-term outcomes of @entity75 following a rotational atherectomy (ROTA). In this retrospective study, @entity1 that had undergone a ROTA of the bifurcation coronary lesions in Juntendo University Hospital (Tokyo, Japan) were enrolled between January 2007 and December 2009, and received follow-up for a median duration of 48 months (range, 12-84 months). A total of 337 @entity1 were enrolled. Each @entity1 was treated with an average of 1.2  0.4 ROTA burrs (mean size, 2.9  0.3 mm). Baseline lesion length, reference diameter, @entity5562 ( @entity5562 ) and percentage of diameter stenosis (%DS) prior to the procedure were comparable between the @entity3918 and non- @entity3918 @entity1 . Furthermore, @entity5562 , %DS and @entity697 following the procedure were similar between the two groups. At follow-up, @entity3918 @entity1 exhibited a significantly decreased @entity5562 (1.97  0.92 vs. 2.26  0.73 mm; P=0.0038), increased %DS (27.9  21.3 vs. 20.2  13.3%; P=0.022) and late loss (0.70  0.45 vs. 0.42  0.36 mm; P=0.0047) compared with the non- @entity3918 @entity1 . Follow-up examinations (mean duration, 52.2  19.4 months) revealed that the @entity3918 @entity1 experienced significantly higher rates of @entity75 revascularization (TLR) [28 (15.7%) vs. 8 (5.0%); P=0.0011], @entity75 ( @entity75 ) restenosis [46 (25.8%) vs. 20 (12.6%); P=0.0019] and major adverse @entity299 (MACE) [36 (20.2%) vs. 19 (12.0%), P=0.039] compared with the non- @entity3918 @entity1 . Although the usage of ROTA and drug-eluting stent evidently improved long-term outcomes in @entity1 with @entity75 , @entity3918 remained an independent risk factor for TLR, @entity75 restenosis and MACE. Therefore, the management of @entity3918 in @entity75 treated with ROTA requires increased investigation in future clinical practice.
