Coronary Artery Aneurysm Caused by a Stent Fracture

Int Heart J. 2018;59(1):203-208. doi: 10.1536/ihj.17-081.

Abstract

Coronary stent fracture (SF) is rare as a complication of percutaneous coronary intervention (PCI), and its adverse events are increasingly being recognized with the development in devices of PCI. The major adverse events caused by SFs are in-stent restenosis due to neointimal overgrowth caused by poor drug delivery.1,2) A coronary artery aneurysm (CAA) is a rare complication of SF, but may lead to lethal events such as acute coronary syndrome or rupture of the CAA further leading to cardiac tamponade.3-5) However, the management of CAAs is controversial with or without SF.6) Herein, we report a case of a CAA caused by an SF and discuss the management of CAA complicated with SF, along with a literature review. We suggest that surgical treatment should be considered the higher-priority strategy in the cases of CAA with SF as compared to CAA without SF.
