  • Title: Near-complete aortic mechanical valve dehiscence due to endocarditis reinfection.
    Author: Gerstein NS, Bhamidipati CM, Schulman PM.
    Journal: Echocardiography; 2018 Jun; 35(6):872-875. PubMed ID: 29726029.
    Abstract:
    Prosthetic valve infective endocarditis (IE) is one of the most serious postimplantation complications. Prosthetic aortic valve IE constitutes 1%-6% of all prosthetic valve IE cases. We present a dramatic echocardiographic case of prosthetic aortic valve IE leading to near-complete valve dehiscence. Echocardiographic evidence of prosthetic aortic valve rocking motion is indicative of significant dehiscence. Aside from IE, other causes and risk factors for prosthetic aortic valve dehiscence include inflammatory and autoimmune vasculitides, concomitant ascending aorta aneurysm, and aortic root calcification.
