Abstract
Coronary stent fracture is an often unrecognized cause of target vessel failure, however, it has been reported more frequently in the drug-eluting stent era. Clinical presentation of stent fracture may range from benign in-stent restenosis to potentially fatal acute stent thrombosis. Interventional treatment of stent thrombosis can be carried out by high pressure balloon dilatation or second stent implantation into the stented segment after thrombus aspiration. Intravascular ultrasound is mandatory in order to exclude mechanical problems in the background of the stent thrombosis and to achieve good final stent apposition and expansion. We report on a stent fracture induced stent thrombosis occurring in a highly calcified proximal right coronary artery. (Treated previously with rotational atherectomy in the middle part, but not in the aortoostial location.) Our case emphasizes the importance of opitimal plaque modification with rotational atherectomy in a calcified aorto-ostial segment of right coronary artery to prevent long term complications such as stent thrombosis or restenosis due to stent fracture.
