The median age at implantation was 3.2\u2009years (interquartile range: 0.9\u20138.4), and 33% of patients were infants. The patch was used mainly in redo surgeries (89.6%). Intra-procedural feasibility and reinterventions were analysed. Primary end points were death or patch-related reoperation\/stent implantation. Explanted patches were stained for recellularization\/calcification, or to reveal proliferation\/inflammation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>A total of 81 patients, who received patches in 119 separate locations, were followed within a median of 20\u2009months (interquartile range: 10.2\u201330.2). Patients with early reoperation\/stent implantation were excluded from follow-up. No patch-related death was noted. Survival at last follow-up was 88% (95% CI: 78.8\u201393.7%). Overall probability of freedom from reoperation\/stent implantation per location, 12 and 24\u2009months after initial surgery was 85.8% (95% CI: 76.2\u201391.7%) and 78.7 (95% CI: 65.9\u201387.2%), respectively. At 20\u2009months, superficial proliferation with discrete macrophage activity was seen in explants; however, no signs of calcification are observed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The initial experience with the Matrix Patch in PAs showed comparable results to other xenogeneic patch materials.
