Folge: Stenose oder Insuffizienz. Structural valve deterioration results in stenosis or regurgitation through the valve.
Strutbruch, Occluderbruch, Bewegungseinschränkung: For ‘mechanical valves’, haemodynamic dysfunction can occur as a result of strut fracture, occluder fracture or escape, loss of leaflet mobility (not due to thrombus, pannus, or vegetation) or ball variance (due to lipid adsorption on the ball of old model Starr-Edwards valves), sewing cuff separation from housing.7,118
Häufig Verkalkung der Segel, selten Deformierung. For ‘bioprosthetic valves’, haemodynamic dysfunction (stenosis or regurgitation) usually occurs with calcification or tearing of the cusps but occasionally fracture of the stent sewing cuff separation from stent, or valve deformation.
