| Description | Journal: Journal of Thoracic and Cardiovascular Surgery This study was aimed to investigate the influence of choice of prosthesis (bioprosthetic valves or mechanical valves) on intermediate-term outcomes in patients on hemodialysis undergoing aortic valve replacement (AVR). A multi-institutional retrospective cohort study was conducted in 18 Japanese centers. All adult patients on chronic hemodialysis who underwent AVR from 2008 and 2015 were included (n=491). The early and late results were compared between groups. The hazard ratios (HRs) were calculated using Cox regression and Fine-Gray models with adjustment for propensity score based on 40 confounders. The mean follow-up period was 2.5±2.1 years (up to 8.3 years) with 98% completeness. There were 323 patients who received a bioprosthetic valve (group B), and 168 patients who received a mechanical valve (group M). There was no significant difference for in-hospital death rate between groups (group B: 12.1%; group M: 8.9%; p=0.29). The overall survival rate at 5 years after surgery was 39.3% in group B and 50.4% in group M (p=0.42). Freedom from reoperation at 5 years was 97.1% in group B and 97.8% in group M (p=0.88). On propensity-score adjusted analyses, there were no significant differences in overall survival between groups. There were no significant differences in overall survival between bioprosthetic valves and mechanical valves in patients on hemodialysis undergoing AVR. |
