Abstract

We present a case of infective endocarditis (IE) of the aortic valve, mitral valve, and aortomitral curtain caused by Gemella sanguinis. The patient was an otherwise healthy 53-year-old male without significant risk factors for infective endocarditis in his medical history. Due to the extent of the infective endocarditis and the rapid deterioration of his clinical condition, which included respiratory failure and severe heart failure, the patient was treated with urgent surgery (a Commando operation where both the aortic and mitral valves were replaced and the aortomitral curtain was reconstructed), broad-spectrum antibiotics, and aggressive postoperative measures such as venovenous (VV) extracorporeal membrane oxygenation (ECMO). This is the first reported case where the aortic valve, mitral valve, and aortomitral curtain were affected by G. sanguinis.

Keywords: aortic valve abscess; aortic valve replacement; gemella; gemella sanguinis; infective endocarditis; mechanical valve; mitral valve replacement; vv ecmo.
