title: Fracking the Code to Complete Revascularization.
abstract: Provisional use of rotational atherectomy (RA) is indicated for procedural success in heavily calcified lesions. In the current study, RA use at three high volume percutaneous coronary intervention (PCI) centers between 2005 and 2013 was 1.4%. MACE rate was 17.8% at median follow-up of 22 months. Peripheral vascular disease (PVD), diabetes mellitus (DM), acute coronary syndrome (ACS), and SYNTAX > 23 were found to be independently associated with MACE. With increasing complexity of disease and SYNTAX score, there is usually an increase in severity of calcification and need for atherectomy. Complete revascularization with residual SYNTAX reduced to < 8 is associated with improved outcomes. Incompleteness of revascularization in patients with SYNTAX > 33 rather than procedural success of the target vessel with atherectomy may have contributed to the adverse outcomes.
