BACKGROUND: In heavily calcified lesions, @entity717 ( @entity717 ) improves procedural success and facilitates stent deployment. Reports on @entity717 in the drug-eluting stent (DES) @entity7971 are limited. The objective of this study was to determine the presenting characteristics, procedural and in-hospital clinical outcomes of @entity1 who underwent @entity717 at our institution in the DES @entity7971 . METHODS: Consecutive cases involving @entity717 between January 1, 2004 and December 31, 2009 at a private, tertiary referral hospital were reviewed retrospectively. RESULTS: A total of 158 @entity1 (236 lesions) who underwent @entity717 are described, including 112 @entity1 (158 lesions) with subsequent DES implantation, 19 @entity1 (28 lesions) with bare-metal stent (BMS) implantation, and 27 @entity1 (50 lesions) with no stent. @entity717 was utilized to modify heavily calcified plaque (84%), as bail-out therapy (16%), to preserve the patency of sidebranches (25%) and as debulking therapy for chronic @entity432 (13 lesions) and in-stent restenosis (7 lesions). DES were not placed in 46 @entity1 (23%) due to reference vessel diameter < 2.25 or > 3.75 mm, inability to deliver @entity4743 , or desire to avert @entity1397 therapy. Angiographic and procedural success rates were significantly higher in the DES and BMS groups compared with the no stent group (angiographic success: 99.1% for DES versus 95% for BMS versus 63% for no stent; p < 0.05; procedural success: 96.4% for DES versus 95% for BMS versus 63% for no stent; p < 0.05). CONCLUSION: In the DES @entity7971 , @entity717 remains utilized primarily to modify heavily calcified plaque. In unadjusted analysis, procedural success appears high with subsequent stent placement (DES or BMS) versus @entity717 alone. However, 1 in 4 are not candidates for stent placement, and the lower procedural success rate in this population should be considered prior to embarking on @entity717 .
