What are the complications of prosthetic valves ?

What are the complications of prosthetic valves ?

 • Thromboembolism. 

• Valve dysfunction, including valve leakage, valve dehiscence and valve obstruc-tion due to thrombosis and clogging. Perivalvular leak is always abnormal. 'Built-in' transvalvular leakage should be less than 10 mi per beat. The loss of expected valve sounds is an important sign of mechanical valve thrombosis. 

• Bleeding (such as upper gastrointestinal haemorrhage) due to anticoagulants. 

• Haemolysis at the valve, causing anaemia. • Endocarditis, which carries a mortality rate of up to 60%; patients should be urgently referred to a tertiary cardiothoracic centre (see pp 57-60).

 • Structural dysfunction: fracture, poppet escape, cuspal tear, calcification. 

• Non-structural dysfunction: paravalvular leak, suture/tissue entrapment, noise.
