Dear Mr Gaffney,

Your request for information relating to UCLH Foundation Trust has been
processed.

Request and Response

1) Which type of existing heart valve is replaced by which choice of
Heart valve (mechanical vs biological)?

Any of the types of valve can be used to replace any of the 4 heart
valves. However, the choice is usually dictated by the type of disease, co
morbidity which may affect bleeding risks and by the patients preference
in consultation with the consultant in charge of the patients care.

2) What are the mortality rates from the initial operation in the
short term(1 year) and the long term...for each type of heart valve
Operation and the chosen replacement?

We do not collect 1-year mortality. We only collect in-trust mortality as
this is needed by Central Cardiac Audit Database ( CCAD).

The analysis you are requesting would normally have to be under-taken by a
research project.

3) How often do the mechanical and biological valves require
Replacement?

This varies between different Pts. Biological valves deteriorate over
time and mechanical valves vary in rate of replacement due to valve
infections / mechanical valve leaks etc. Again this sort of analysis
would normally come under the remit of a research project.

4) Who makes the biological and mechanical heart valves used at your
Hospital.

St Jude Medical

Sorin

Edwards Lifesciences
