Mid-Term Valve Performance and Durability of the Ozaki Procedure in Patients on Chronic Dialysis

This retrospective study evaluated the hemodynamics and durability of the Ozaki procedure in chronic dialysis patients compared to two groups: non-dialysis Ozaki patients and dialysis patients receiving bioprosthetic aortic valve replacement (AVR), during a 20-year period. Propensity and age-matching of 155 dialysis Ozaki patients against 121 non-dialysis Ozaki patients and 125 bioprosthetic AVR patients demonstrated excellent mid-term outcomes. At five years, the dialysis Ozaki cohort had comparable freedom from reoperation (91 percent vs 96 percent, p=0.4) compared to non-dialysis patients.  Furthermore, compared to bioprosthetic AVR, the Ozaki group exhibited significantly lower mean gradients (11 versus 14 mmHg, p0
