Left ventricular free-wall rupture: An unusual presentation of non-bacterial thrombotic endocarditis.

Non-bacterial thrombotic endocarditis (NBTE) is a rare, often asymptomatic, condition. A 55-year-old woman presented with hemiparesis, facial palsy and chest pain. After urgent investigation, she was referred as a case of type A aortic dissection complicated by tamponade, myocardial infarction and stroke. Review of her imaging identified haemopericardium but no dissection, and emergency surgery proceeded considering her unstable condition. She underwent an emergency repair of left-ventricular free-wall rupture and excision of an aortic valve vegetation. Postoperative investigations confirmed a diagnosis of NBTE in the setting of a plexiform neurofibroma, and she was discharged 9 weeks later with residual neurological symptoms. This case poses a previously unreported acute presentation of NBTE and highlights the complexities in its diagnosis and management.
