Popis: The Ozaki procedure is an innovative surgical technique aiming at the reconstruction of the aortic valve with autologous pericardium to overcome the limitations of commercially available prostheses.We retrospectively analysed 71 patients who underwent Ozaki operation at our centre between October 2014 and February 2020.No in-hospital death occurred. Freedom from major adverse valve-related events (MAVRE) was 97%. The aortic gradients and transvalvular velocity are significantly lower at the 3-months echocardiographic control than at the pre-discharged echocardiography (10.93 ± 5.38, p= 0,0003 vs 16.24 ± 7.67 p= 0,0004 respectively). The median follow-up period was 20.7 months (range 2 to 47 months). Four patients showed mild/moderate aortic insufficiency (5.6%) and none showed severe aortic valve insufficiency. No patients underwent reoperation.Mid-term outcome follow-up of Ozaki procedure showed optimal results in term of mortality, transaortic valve gradients, freedom from MAVRE and recurrence of aortic valve insufficiency.
