Summary
Embolic infarction from mitral valve endocarditis caused a large heart attack. While the mitral valve recovered, a coronary aneurysm developed after treatment.
Area of Science:
- Cardiology
- Infective Endocarditis
- Interventional Cardiology
Background:
- Mitral valve endocarditis can rarely lead to embolic infarction.
- Large vegetations pose a significant risk for systemic embolization and subsequent organ damage.
Observation:
- A patient presented with a large (15 mm) linear vegetation on the anterior mitral leaflet, extending into the aortic valve orifice during systole.
- This valvular mass caused a severe anterior wall myocardial infarction, necessitating urgent primary angioplasty due to hemodynamic instability.
Findings:
- Primary angioplasty successfully treated the acute myocardial infarction.
- At 3-month follow-up, the mitral valve showed favorable recovery.
- However, a large mycotic coronary aneurysm formed at the angioplasty site, and significant sequelae from the myocardial infarction persisted.
Implications:
- This case highlights the complex management of embolic complications from mitral valve endocarditis.
- It underscores the potential for delayed complications, such as mycotic aneurysms, following interventions for myocardial infarction in the context of endocarditis.
- Careful monitoring is crucial after treating such cases to detect and manage late sequelae.
