Recambio valvular aórtico mediante prótesis sin sutura en pacientes con estenosis aórtica grave y alto riesgo quirúrgico: revisión sistemática

Sutureless aortic valve replacement is perceived to be an alternative treatment for high surgical risk patients with severe aortic stenosis. This work presents the results of a systematic review undertaken to assess the effectiveness and safety of this procedure. Eight low quality case series were identified. Six focused on prosthesis ATS 3f Enable® and 2 on Perceval S. Results show good haemodynamic and clinical results for both prosthesis. Implantation of ATS 3f Enable® valves was successful in more than 85% of the patients and the mean cardiopulmonary bypass (BCP) time ranged from 58 to 85 minutes. For Perceval S, implantation was successful in all patients and the mean BCP time was less than 30 minutes. Since there are no long term follow-up studies, the durability of the prosthesis and the appearance of late complications is uncertain.
