Pericardio autólogo para pacientes adultos y ancianos sometidos a reemplazo de válvula aórtica: Una Revisión Sistemática

Ozaki et al. first performed aortic valve replacement using autologous pericardium in 2007. Compared to mechanical and bioprosthetic valves which have apparent disadvantages, this technique has been an alternative with a promising safety and efficacy result. A comprehensive search was carried out in 4 databases (Pubmed, Cochrane Library, Proquest, Scopus) from February to March 2021 using search terms “autologous pericardium”, “aortic valve replacement”, and “aortic valve reconstruction”. Outcomes measured in this study were mortality, freedom of operation, thromboembolic and endocarditis event, and echocardiography finding. Risk bias of all studies was measured using MINORS criteria. A total of 12 studies involving 1427 subjects were included. The mean age was 64.95 years and 52.1% subjects were male. Mortality due to cardiac and noncardiac cause was 1.75%. Reoperation was needed in 1.12% subjects. Thromboembolic and endocarditis events occurred in 0.21% and 0.91% respectively. All studies reported lower average peak pressure gradient after surgery. Aortic valve replacement using autologous pericardium has a tolerable safety and efficacy.
