Key result
Self-apposing stent linked to coronary evagination at 4 years with normal flow requiring no intervention.
Why the study?
Coronary evagination is linked to adverse long-term outcomes and its pathogenesis is incompletely understood, with certain stents such as self-expandable stents being a frequent cause of vascular remodeling.

Self-apposing stents may be associated with the late development of coronary evagination, suggesting a potential role of chronic outward force in positive vessel remodeling.
May be observed without clinical consequence after self-apposing stents; leaves open whether outward force promotes late vessel remodeling.
Kontext: Evaginace (vychlĂpenĂ) koronĂĄrnĂ tepny je abnormalita spojenĂĄ - bez ohledu na (ne)pĹĂtomnost ischemickĂŠ choroby srdeÄnĂ (ICHS) - s nepĹĂznivĂ˝m dlouhodobĂ˝m vĂ˝slednĂ˝m stavem. Patogeneze evaginace koronĂĄrnĂ tepny nenĂ zcela objasnÄna; za prediktory zvÄtĹĄenĂ koronĂĄrnĂ tepny pĹŻsobenĂm mechanismĹŻ, jako jsou dlouhodobÄ probĂhajĂcĂ zĂĄnÄt, suboptimĂĄlnĂ endotelizace a pozitivnĂ remodelace cĂŠv, jsou povaĹžovĂĄny intrakoronĂĄrnĂ manipulace a perkutĂĄnnĂ koronĂĄrnĂ intervence (PCI). ÄastÄjĹĄĂ pĹĂÄinou remodelace cĂŠv jsou nÄkterĂŠ typy stentĹŻ, napĹĂklad samoexpandibilnĂ stenty. Popis pĹĂpadu: Popisujeme pĹĂpad 79letĂŠ Ĺženy, kterĂĄ podstoupila perkutĂĄnnĂ koronĂĄrnĂ intervenci pro nĂĄmahovou anginu pectoris a jĂĹž jsme implantovali samoexpandibilnĂ stent v mĂrnÄ ektatickĂŠm segmentu r. circumflexus levĂŠ koronĂĄrnĂ tepny a klasickĂ˝ stent pro lĂŠÄbu jinĂŠ lĂŠze s dobrĂ˝mi vĂ˝sledky. O ÄtyĹi roky pozdÄji prokĂĄzalo koronarografickĂŠ vyĹĄetĹenĂ aneurysma obklopujĂcĂ dĹĂve implantovanĂ˝ samoexpandibilnĂ stent; nicmĂŠnÄ prĹŻtok koronĂĄrnĂmi tepnami byl normĂĄlnĂ, takĹže nebylo zapotĹebà ŞådnĂŠ dalĹĄĂ intervence. ZĂĄvÄry: Pokud je nĂĄm znĂĄmo, nĂĄĹĄ ÄlĂĄnek popisuje jako prvnĂ Ăşlohu implantace samoexpandibilnĂho stentu pĹi vzniku evaginace; popis pĹĂpadu z klinickĂŠ praxe mĹŻĹže bĂ˝t uĹžiteÄnĂ˝ v tom smyslu, Ĺže upozorĹuje na moĹžnost tĂŠto situace u pacientĹŻ po PCI, jimĹž byl implantovĂĄn tento typ stentu.

Venuti et al. (2023) conducted a case report in Coronary evagination (n=1). STENTYS Xposition S self-Apposing stent was evaluated on Coronary evagination progression. A 79-year-old woman developed a coronary evagination surrounding a previously implanted self-apposing stent at 4-year follow-up, with normal coronary flow requiring no further intervention.
