Advancing Heart Valve Replacement: Risk Mitigation of Decellularized Pulmonary Valve Preparation for Its Implementation in Public Tissue Banks by Rodríguez Martínez JI, Castells-Sala C, Piteira AR, Montagner G, Trojan D, Martinez-Legazpi P, Acosta Ocampo A, Fernández-Santos ME, Bermejo J, Jashari R, Pérez ML, Agustí E, Tabera J, Vilarrodona A

“…The present study aims to document the work performed for the safe implementation in public tissue banks of a new decellularization method for human pulmonary heart valves, based on previous risk evaluation.Methods: After assessing new preparation method associated risks, using EuroGTP-II methodologies, an extensive array of in vitro studies were defined to validate the new technique, mitigate the risks and provide quality and safety data.Results: Initial evaluation of risks using EuroGTP II tool, showed Final Risk Score of 23 (high risk), and four studies were devised to mitigate identified risks: (i) tissue structure integrity; (ii) cell content; (iii) microbiological safety; and (iv) cytotoxicity evaluation in final tissue preparation. …”
