Mycotic aneurysm of left anterior descending artery after sirolimus‐eluting stent implantation: A case report

Abstract

We report a case of mycotic aneurysms due to Staphylococcus aureus infection in the left anterior descending coronary artery in a 56-year-old male after implantation of a sirolimus-eluting stent. This is an unreported complication of a drug-eluting stent.

Successful Surgical Treatment of an Infected Right Coronary Artery Aneurysm-to-Right Ventricle Fistula after Sirolimus-eluting Stent Implantation

“…There has been no recurrence of fever or angina in the past 16 months. Table 1 (5,6,(10)(11)(12)(13)(14)(15)(16)). Bacterial cultures of blood in the present case repeatedly grew S. aureus (Fig.…”

“…Recently, coronary artery aneurysm formation is considered as one of complications after the use of sirolimus-eluting stent (SES), which markedly reduces the restenosis rate after coronary angioplasty (3,4). (5,6). Furtermore, the incidence of infected aneurismal fistula formation after stenting SES has not been presented.…”

Pseudoaneurysm and Intracardiac Fistula Caused by an Infected Paclitaxel-Eluting Coronary Stent

“…Potential causes for drugeluting stent infections include impairment of local immunosuppression and endothelialization caused by the paclitaxel or sirolimus released from the stent and/or bacteremia at the time of catheterization. [1][2][3][4] In fact, Ramsdale et al reported that up to 17.7% of patients who underwent complex percutaneous coronary interventions had detectable bacteremia. 5 Further investigation is warranted to determine whether drugeluting stents have a higher propensity for contamination versus bare-metal stents and whether prophylactic antibiotics should be administered for drug-eluting coronary stent implementation, particularly in complicated percutaneous coronary interventions.…”

“…[1][2][3][4] In all cases S. aureus bacteremia was responsible for causing mycotic stent complications. Although mycotic aneurysms, pseudoaneurysms, and abscesses have been previously reported in both bare-metal and drug-eluting stent infections, this is the first reported case of an infected coronary stent that developed an intracardiac fistula.…”

Aneurisma coronariano micótico: relato de dois casos

“…Therapy with intravenous antibiotics was chosen, however, considering that foreign body infections are extremely resistant to antibiotics, surgical debridement and/or stent removal could be necessary 5 . Our cases were managed with endovenous therapy, reaching a survival of 50%.…”
