Haemophilus parainfluenzae infective endocarditis complicated by multiorgan septic emboli.

Infective endocarditis (IE) caused by Haemophilus parainfluenzae is a rare but serious condition if not diagnosed and treated promptly. In this article, we describe a patient with H. parainfluenzae IE who initially presented with non-specific symptoms but subsequently developed multiple sequelae of IE. The diagnosis of IE was made based on clinical, echocardiographic, radiological and microbiological findings. He was treated successfully with a mitral valve replacement along with 4 weeks of intravenous antibiotic therapy. Our case highlights the importance of obtaining a thorough history and a complete physical examination to ensure an early diagnosis of IE.
