Impact of stentablation with rotational atherectomy in coronary microcirculatory function

Abstract

Key Clinical Message Stentablation (SA) has been used as a bailout method for undilated, under‐expanded stents, but one reason that SA is associated with a high rate of major adverse cardiac events may be its adverse effect on microcirculation. Consequently, appropriate lesion preparation should always be considered for heavily calcified lesions to avoid such complications. Abstract Under‐expansion of the coronary stent is associated with increased rates of in‐stent restenosis and thrombosis. Stentablation (SA) with rotational atherectomy is used in the treatment of undilatable, under‐expanded coronary stents; however, its effect on coronary microcirculatory function remains unclear. This novel report compares microcirculation indices before and after SA.
