Extensive aortic valve ring abscess formation: a rare complication of Q fever endocarditis.

We report the successful management and 2 year follow up of a young patient with Q fever endocarditis on a congenitally bicuspid aortic valve complicated by extensive abscess formation in the aortic valve ring and interventricular septum. Aortic root abscess formation complicating Q fever endocarditis has been reported in only one previous patient. Serological tests may thus be indicated in patients with aortic abscesses. Despite extensive aortic and intramyocardial abscess formation it proved possible to control the progression of disease by open drainage of the abscess and aortic valve replacement. Although the requirement for aortic root replacement was anticipated in this patient, it has not been required. [ABSTRACT FROM PUBLISHER]
