Coronary artery aneurysm formation following implantation of a bioresorbable vascular scaffold for in-stent restenosis

Coronary artery aneurysm (CAA) formation is a rare complication of coronary intervention that may develop after implantation of bare-metal or drug-eluting stents. The etiology of this entity appears to be multifactorial and its prognosis is poorly understood, but it has been associated with an incre...

Description
Summary:Coronary artery aneurysm (CAA) formation is a rare complication of coronary intervention that may develop after implantation of bare-metal or drug-eluting stents. The etiology of this entity appears to be multifactorial and its prognosis is poorly understood, but it has been associated with an increased risk of stent thrombosis. To date few cases of CAAs related to bioresorbable vascular scaffold (BVS) implantation have been reported, and the development of CAA after BVS implantation for the treatment of in-stent restenosis (ISR) has not been previously described. Here we present two cases of CAA formation after BVS, which represent the first demonstration of CAA formation after the use of BVS for ISR. Resumo: A formação de um aneurisma coronário (CAN) é uma complicação rara após intervenções coronárias. O CAN pode se desenvolver após stent convencional (BMS) e implante de stent farmacológico (DES). A etiologia desta patologia parece ser multifatorial e o prognóstico permanece mal elucidado, mas tem sido associado com um aumento do risco de trombose de stent. Até à data, apenas alguns casos de CAN relacionadas com scaffold bioabsorvível (BVS) foram relatados. O desenvolvimento de CAN após o implante de um BVS para o tratamento da reestenose intra-stent (ISR) não foi anteriormente descrito. Aqui apresentamos dois casos de formação CAN após a BVS, que representam a primeira demonstração de formação CAN após o uso da BVS para ISR.
