Mitral valve plasty in a patient with multiple cerebral cavernous malformations: A case report.

Cerebral cavernous malformations (CCMs) are blood vessel malformations, often untreated if asymptomatic. However, upon cardiac surgery with cardiopulmonary bypass, cerebral edema/hemorrhage may occur. We successful performed mitral valve plasty for a case of severe mitral regurgitation with multiple CCMs. Preoperative head magnetic resonance imaging and strict perioperative management are important.
