Stent Infection Leading to Coronary Aneurysm and Coronary Cameral Fistula.

ABSTRACT:

Background

Coronary stent infection (SI) is a rare but catastrophic complication, occurring in 0.3% to 6% of cases post-percutaneous coronary intervention (PCI). Early diagnosis and surgical interventions are crucial for definitive diagnosis and management.

Case summary

A 52-year-old man underwent PCI for an inferior wall myocardial infarction to the left circumflex artery (LCx) with a single sirolimus-eluting stent. He developed a fever 10 days later due to methicillin-sensitive Staphylococcus aureus. Imaging showed a coronary cameral fistula with a left atrial appendage (LAA) mycotic aneurysm. He was treated with antibiotics, stent explantation, abscess drainage, and fistula repair; however, he developed refractory vasoplegia and died 2 days post-surgery.
