| Popis: | Valve Stability and Pseudoendothelialization Fears of calcium resorption leading to loss of valve fixation over the intermediate term are likely unfounded. In this patient, despite minimal initial native aortic cusp calcification, the valve was tenaciously fixed. Whether tissue in-growth contributed is unclear. This valve, particularly the uncovered upper stent cells, was not fully covered in pseudoendothelium 11 months later. Although beneficial near the coronary ostia (possibly caused by high flow), retarded pseudoendothelialization might require antiplatelet therapy postoperatively. Paravalvular leak might further disrupt tissue coverage. Finally, cusp integrity was lost early, probably accelerated by infection and high flow with (paravalvular) AR. Further evaluation of long-term durability, function, and tissue coverage is needed. |
