Key result
Valve-sparing surgery successfully treats an MAIVF pseudoaneurysm complicating infective endocarditis without valvular involvement.
Why the study?
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa can be a catastrophic sequela of untreated active infective endocarditis, and this case highlights the rare presentation without valvular involvement and the role of transesophageal echocardiography.
Case Report (n=1)
No
Highlights the utility of transesophageal echocardiography in diagnosing rare complications of infective endocarditis such as p-MAIVF without valvular involvement.
May support valve-sparing surgery in select young patients; leaves open durability and generalizability.
A pseudoaneurysm of the mitral-aortic intervalvular fibrosa (p-MAIVF) can be a catastrophic sequela of untreated active infective endocarditis. We describe a case of infective endocarditis complicated by p-MAIVF without valvular involvement. This case highlights the importance of this rare clinical entity and of transesophageal echocardiography in reaching a diagnosis. (Level of Difficulty: Beginner.)

Kuroda et al. (2020) conducted a case report in Infective endocarditis complicated by pseudoaneurysm of the mitral-aortic intervalvular fibrosa (n=1). Valve-sparing surgery and antibiotics was evaluated. A 20-year-old man with infective endocarditis complicated by a pseudoaneurysm of the mitral-aortic intervalvular fibrosa without valvular involvement was successfully treated with valve-sparing surgery.
