Intrastent Coronary Pseudoaneurysm in the Setting of Primary Angioplasty: An Early Presentation

Ankit Kumar Sahu , Naveen Chandra

Pseudoaneurysm formation is an uncommon but dreaded complication of percutaneous coronary intervention (PCI). Herein, we describe the case of a patient who developed symptomatic pseudoaneurysm within a month of primary PCI using a zotarolimus eluting stent (ZES). Despite a review of the literature and an examination of the procedural data, we were not able to explain the definite mechanism of pseudoaneurysm formation in our case. We assume that there was stent strut malapposition leading to non-angiographically visible dissection that provoked this phenomenon.
