title: [Acute Actinobacillus actinomycetem comitans aortic endocarditis].
abstract: A 55 year old man presented an acute massive primary aortic endocarditis, with blood cultures showing the presence of Actinobacillus actinomycetem comitans. The rapidly worsening character of this endocarditis, which required an emergency valve replacement, was the hallmark of this case. The clinical and haemodynamic signs of the often missed massive acute aortic incompetence are recalled.
