Reviewing surgical video from a case study, we explore the complexity of diagnosing mitral valve endocarditis, especially when there is a risk of embolism. In this discussion we review:

• The key role that echocardiography plays in accurate diagnosis and management of native mitral valve endocarditis
• The importance of thorough CT exams to evaluate the possibility of systemic and cerebral septic embolic events 
• Optimal timing and technique for surgical intervention when there is a risk of cerebral embolic events
