Paper Abstract
Patients suffering from a heart valve deficiency are often treated by replacing the valve with an artificial or
biological implant. In case of biological implants, the use of porcine heart valves is common. Quality assessment
and inspection methods are mandatory to supply the patients (and also medical research) with only the best
such xenograft implants thus reducing the number of follow-up surgeries to replace worn-up valves. We describe
an approach for automatic in-vitro evaluation of prosthetic heart valves in an artificial circulation system. We
show how to measure the orifice area during a heart cycle to obtain an orifice curve. Different quality parameters
are then estimated on such curves.
