Incomplete stent apposition: should we appose or oppose?
ncomplete stent apposition (ISA), also known as stent alapposition, is defined most simplistically as the absence f contact between stent struts and the vessel wall not verlying a side branch. Incomplete stent apposition can ccur at the time of stent implantation—acute ISA—which ight either resolve or persist at follow-up (late-persistent SA). Patients without ISA at the time of stent implantai...
متن کاملWhat to do about late incomplete stent apposition?
Acute and subacute stent thromboses have existed since the first stent implantation procedures. Initially recognized as a complication of brachytherapy, late stent thrombosis has become a public health issue only during the current era of drug-eluting stent (DES) implantation, as evidenced by the March 8, 2007, issue of the New England Journal of Medicine, which includes 5 articles, 2 perspecti...
متن کاملMechanisms, pathophysiology, and clinical aspects of incomplete stent apposition.
Incomplete stent apposition (ISA) is characterized by the lack of contact of at least 1 stent strut with the vessel wall in a segment not overlying a side branch; it is more commonly found in drug-eluting stents than bare-metal stents. The accurate diagnosis of ISA, initially only possible with intravascular ultrasound, can currently be performed with higher accuracy by optical coherence tomogr...
متن کاملWhy are we so concerned with acute incomplete stent apposition?
In their article, Shimamura et al. report that incomplete stent apposition (ISA) was observed in all 38 everolimus-eluting stents (EES) and all 39 sirolimus-eluting stents (SES) post-percutaneous coronary intervention (PCI) (measuring 315+ 94 mm and 0.50+0.24 mm in EES and 308+ 119 mm and 0.95+ 0.70 mm in SES), that it persisted in 26% of EES and 38% of SES at 8–12 months although the size of t...
متن کاملIncomplete stent apposition and very late stent thrombosis after drug-eluting stent implantation.
BACKGROUND Stent thrombosis may occur late after drug-eluting stent (DES) implantation, and its cause remains unknown. The present study investigated differences of the stented segment between patients with and without very late stent thrombosis with the use of intravascular ultrasound. METHODS AND RESULTS Since January 2004, patients presenting with very late stent thrombosis (> 1 year) afte...
