Abstract
Introduction: Coronary stent underexpansion is associated with in-stent restenosis and few interventions are available for the management of undilatable underexpanded stents. Stentablation (SA) with rotational atherectomy (RA) is a unique application and has previously been described with encouraging results. Data regarding SA is limited to case reports and small case series; therefore, reasonable concern persists regarding procedural safety and long-term outcomes. Methods: This is a single-center retrospective study analyzing twenty consecutive patients who underwent SA with RA. The primary endpoint was procedural success and secondary endpoints included procedural safety outcomes and major adverse cardiac events (MACE) over a 12-month follow-up period. Results: Stentablation and secondary stenting were guided by intravascular ultrasound and procedural success was achieved in all cases. No in-hospital death or MACE was observed. The prevalence of MACE was 5% at 30 days as one patient developed recurrent MI without target lesion revascularization (TLR). At 12 months, MACE had occurred in 40% of patients, however this was strongly driven by a high prevalence of TLR (30%). Only one cardiac death (5%) and one additional NSTEMI were observed during the 11 additional months of follow up. Conclusion: Stentablation with RA is a feasible and effective option for the acute management of symptomatic, underexpanded, and undilatable coronary stents. SA is associated with a high rate of procedural success as well as excellent in-hospital and short-term outcomes. However, our study population demonstrated substantial MACE at 12 months which was strongly driven by TLR and associated with minimal mortality.
