We read with interest the letter by Dr Baciewicz regarding his experience of two young female patients with prosthetic valve dysfunction as a result of pannus formation. In our study, we showed histologic and immunohistochemical findings of pannus tissue that caused prosthetic valve dysfunction after aortic valve replacement. We believe that our study provides information useful to elucidate the mechanisms of pannus formation in patients receiving prosthetic valves. We also think, however, that our findings are not sufficient to reach conclusion regarding the complete pathogenetic mechanisms of this disorder, and further prospective studies including more patients and control specimens are required.
The sizes of the prosthesis explanted in this study were 21 mm in 6 patients (all female), 23 mm in 2 (1 male and 1 female), 25 mm
