| Bank | Number of donors/no. of grafts processed annually (Average) | Proportion of products meeting release criteria | Reasons for product failure | Proportion of released products implanted | Reasons released products not implanted |
|
| N2 | 55 donors
70 valves | ~70% | (1) Abnormal morphology of graft
(2) Positive serology results of donor
(3) Positive microbiological results of graft
(4) Donor related | 100% for pulmonary valves
20% for aortic valves | Low demand for aortic valves |
|
| N3 | 42 donors
68 grafts | ~78% | Positive microbiological results of graft | 32% of grafts were confirmed to be implanted,
16.5% of grafts were exported | Low demand for aortic valves |
|
| N4 | 2400 grafts | ~60% | (1) Positive microbiological results of graft
(2) Quality/donor related | 80% | (1) Size demand for valves
(2) Nonvalve grafts are not in demand |
|
| N5 | 3700 donors
8500 grafts (including valves, patches, descending thoracic aorta and pericardium patches) | ~39% | (1) Deferred due to size/type of graft
(2) Graft attribute/abnormal morphology of graft
(3) Positive microbiological results of graft | 99% | Beyond maximum storage duration |
|
| N6 | 34 donors
57 grafts (valves, conduits, and pulmonary hemiarteries) | No response provided | 53% | (1) Intraoperative contamination of graft
(2) Incorrect size of graft
(3) Beyond maximum storage duration |
