Splenic rupture as the presenting symptom in infective endocarditis: a rare and dangerous complication

Infective endocarditis remains a dangerous condition and carries a mortality risk of approximately 20%. Splenic rupture is a rare complication of endocarditis. A 60-year-old woman with a history of atrial fibrillation, mitral valve repair and severe mitral regurgitation was admitted with a fall and abdominal pain. Emergency laparotomy was performed leading to a diagnosis of splenic rupture, for which splenectomy was performed. Four months later, the patient represented with symptoms of a transient ischaemic attack. Transthoracic and transoesophageal echocardiogram confirmed a large vegetation on the anterior mitral valve leaflet. Treatment with antibiotics and re-do mitral valve surgery was performed. The cause of the initial splenic rupture was felt to have been secondary to undiagnosed infective endocarditis. It is imperative to consider endocarditis in a case of spontaneous splenic rupture particularly in high-risk patients such as those with previous valve surgery.
