• Study description:
  Both, acquired and congenital heart disease can require surgical reconstruction or replacement of cardiac valves and/or arteries. Currently available prosthesis materials is not ideal. It may require anticoagulation, with the risk of bleeding, if manufactured from non-organic material, or it may degenerate when derived from animals or human tissue donors. The use of Cell-free Allografts, XFA, may reduce the need for frequent reoperation, especially in children and young adults. The purpose of this investigation is to analyse the performance of XFA for cardiovascular reconstruction, such as valve replacement, regarding re-operation and re-intervention, hemodynamic performance and long term durability. This will be an observational registry study of isolated or combined procedures using XFA. The following outcome variables will be analysed: Primary safety endpoints: Rate of cardiovascular Adverse Reactions, Serious Adverse Reactions, such as infections, immunological reactions. Secondary safety data: Post-operative time until re-operation, re-interventions or death. Primary efficacy endpoint: Rate of freedom from XFA-dysfunction leading to re-intervention or explantation. Secondary efficacy endpoint: Macroscopic changes of XFA after implantation, trans-XFA gradients and XFA-competence, as applicable, assessed by non-invasive imaging tools such as echocardiography.
