Causes of Prosthetic Aortic Valve Malfunction

Description

A prosthetic valve may malfunction if certain conditions occur.

Cause	Stenosis	Regurgitation
stent creep	x
pannus	x	x
calcification	x	x
support structure deformation, fracture, trauma, under-expansion	x
prosthesis-patient mismatch	x
endocarditis	x	x
prosthetic valve thrombosis	x	x
native leaflet prolapse impeding prosthetic valve motion	x
malposition (too high, too low)		x
acute malcoaptation		x
leaflet wear, tear, prolapse, etc		x
suture breakage or disruption		x

where:

• Stent creep is a structural deterioration of a bioprosthetic valve with permanent inward deflection of the stent posts.

• Coaptation refers to the coming together of the heart valves leaflets. Malcoaptation means that the valves do not come together properly, allowing a regurgitant jet.
