Difficult Stentablation with an Episode of Stuck and Entrapped Burr within the Underexpanded Stent

Abstract

Stentablation by rotational atherectomy has been reported as an option to correct underexpanded stents. Due to concerns of excessive stent damage, distal embolization of metal particles, excessive heat generation, and burr entrapment in the stent, stentablation has been considered the last choice to manage underexpanded stents. Here, we report a case of a stuck and entrapped atherectomy burr inside an underexpanded and undilatable stent, which made withdrawal of therotablation burr during rotational atherectomy difficult. After successful stentablation by rotational atherectomy, we were able to complete the percutaneous coronary intervention with another stent.
