Rotational atherectomy of undilatable coronary stents: stentablation, a clinical perspective and recommendation

EuroIntervention. 2016 Aug 5;12(5):e632-5. doi: 10.4244/EIJV12I5A103.

Abstract

Aims: Our aim was to examine procedural viability and midterm outcomes following the use of rotational atherectomy (RA) on malapposed, crippled, otherwise non-salvageable metallic stents (i.e., stentablation [SA]), and convey important procedural pointers for practitioners encountering such situations.

Methods and results: Data on twelve SA subjects were analysed. The primary endpoint was procedural success: effective ablation of the malapposed stent and successful implantation of a new device. Major adverse cardiac events (MACE) and all-cause death at six months following the index procedure were examined as a secondary endpoint. All twelve patients underwent successful SA and novel stent implantation, with sufficient salvage of coronary anatomy (residual stenosis <30%). At six-month follow-up, however, MACE amounted to 50% and all-cause mortality to 25% in the inspected subjects.

Conclusions: We found that, although feasible as an acute salvage option, SA distinctively increases post-procedural midterm MACE and mortality rates. This places emphasis on the importance of avoiding eventual SA situations, underlining the importance of ample lesion preparation prior to stent implantation.
