Cardiovascular Systems reports data from Compliance 360 study comparing orbital atherectomy vs. percutaneous transluminal angioplasty (CSII) 9.08 +0.02 : Study shows that by avoiding stents and reducing restenosis saves money - approximate incremental cost effectiveness of the Diamondback group vs. the percutaneous transluminal angioplasty group at six months was $5,264 per additional acute adjunctive stenting or restenosis avoided... The percutaneous transluminal angioplasty arm required bail-out stenting in 84% of the procedures to achieve results equivalent to the Diamondback arm. Diamondback procedures had lower dissection rates and reduced bail-out stenting, thus preserving future treatment options.
