Clinical course, microbiologic profile, and diagnosis of periannular complications in prosthetic valve endocarditis

Mycotic Aneurysms of Aortic Root and Aorta-to-Left Atrial Fistula Complicating Bicuspid Aortic Valve Endocarditis

“…

valvular abscesses in IE has been detected in 6-9% of the cases [3,4] . In this report, we describe a patient with subacute bicuspid aortic valve endocarditis complicated by aortic insuffi ciency, mycotic aneurysms of the aortic root, and fi stulous communication between the aorta and the left atrium.

Case Report

A 19-year-old man was admitted to a local hospital with ongoing fever, fatigue and weight loss during the preceding 6 months.

Complications of native and prosthetic valve infective endocarditis: Update in 2006

“…Spread of infection in IE from valvular structures to the surrounding perivalvular tissue results in periannular complications that may place the patient at increased risk of adverse outcomes including CHF and death [2,3,6,[20][21][22][23][24][25][26]. Periannular lesions develop from bacterial destruction, invasion of local tissue, and necrosis, leading to abscess formation.…”

Infective endocarditis complicated with left atrioventricular fistula in a 20-year-old patient. A case study

“…It appears in 6-9% of cases of IE on the aortic valve as a consequence of perivalvular abscess [2, 3]. Secondary involvement of the anterior leaflet of the mitral valve, with or without its perforation, may be a result of direct spreading of aortic valve infection.…”
