Fatal infection of coronary stent implantation
1Intensive Care and Infectious Diseases Unit, Lille University Medical School, Tourcoing, France.
Insights
Septic cardiac complications, including infective aneurysms of the left anterior descending (LAD) coronary artery, are rare after percutaneous transluminal coronary angioplasty (PTCA) and stenting. This case highlights a fatal outcome despite surgical repair of a Pseudomonas aeruginosa infection.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Device Complications
Background:
- Systemic infections post-percutaneous transluminal coronary angioplasty (PTCA) and coronary stent implantation are uncommon.
- Septic cardiac complications, such as endocarditis and mycotic aneurysms, represent a rare but serious sequela.
Observation:
- A patient developed infective mitral endocarditis caused by Pseudomonas aeruginosa a few weeks after coronary stent implantation.
- Coronary angiography was performed to investigate potential stent infection, revealing a saccular aneurysm of the left anterior descending (LAD) coronary artery.
Findings:
- The case presented an infective aneurysm of the LAD coronary artery, a rare complication following coronary stenting.
- Despite prompt surgical intervention to repair the infected aneurysm, the patient experienced a fatal outcome.
Implications:
- This case underscores the potential for rare but severe infectious complications associated with coronary stent implantation.
- Early recognition and management of suspected stent infections are crucial, even in the absence of typical endocarditis symptoms.
- Further research into preventative strategies and optimal treatment protocols for septic cardiac complications post-stenting is warranted.
Abstract:
Among systemic infections occurring after percutaneous transluminal coronary angioplasty (PTCA) and coronary stent implantation, septic cardiac complications are rare. We report a new case of infective aneurysm of the left anterior descending coronary artery (LAD) following stent implantation. Infective mitral endocarditis due to Pseudomonas aeruginosa occurring a few weeks after stenting led to search for stent infection. Coronary angiography revealed a saccular aneurysm of the LAD. Despite surgical repair, a fatal outcome resulted.
