Blood in, blood out: left ventricular pseudoaneurysm following mitral valve endocarditis.

A 76-year old male on warfarin due to atrial fibrillation was admitted with Staphylococcus aureus septicaemia. Echocardiography demonstrated mitral valve endocarditis, and shortly thereafter, he suffered an intracranial haemorrhage as a result of septic embolism. Four weeks later, cardiac magnetic resonance imaging revealed a newly formed pseudoaneurysm. A left ventricular pseudoaneurysm caused by infective endocarditis is very rare, but awareness of this unusual complication may allow surgery to prevent rupture.
