Haemolysis : Mechanical valves, bioprosthetic valves as well as valves repaired with annuloplasty rings may cause haemolysis and related anaemia. This is more common when there is para valvar leak, which often results in a turbulent jet, Laboratory investigations reveal anaemia, elevated serum LDH and high reticulocyte aunt. The definitive treatment is by reoperation, fixing the para
valvar leak or by replacement with another valve.
