The functional reliability of mechanical heart valves depends on their manufacturing process, material selection criteria, choice of design, and quality control/quality assurance procedures. hence, the manufacturing practices and quality control procedures of the mechanical heart valve components, the coated frame, the disc, and the sewing ring should be carefully chosen to avoid adverse events in animal/human trials and commercialization. the thickness inspection and component evaluation for batch qualification of ultra-high molecular weight polyethylene (uhmwpe) disc is paramount during commercial production. these requirements and clean room work environment prefer nde technology, which is non-ionizing, non-contact, and non-invasive.
