Complete dislodgement of a deployed coronary stent in a severely calcified lesion

Coronary stent dislodgement (CSD) during percutaneous coronary intervention is a rare complication nowadays, thanks to equipment design and stent technology improvements. Coronary calcification, inadequate lesion preparation and suboptimal stent expansion are some of the risk factors for the occurrence of CSD. On the other hand, complete dislodgement of a deployed coronary stent is extraordinarily rare and infrequently reported in the literature. Herein, we describe a complete CSD case after deployment in a severely calcified right coronary artery lesion and discuss strategies to prevent this severe complication.
