Mitral valve reconstruction by posterior cusp advancement using a pericardial graft. Long-term follow-up in nine patients.

Aortic valve repair by cusp extension with the use of fresh autologous pericardium in children with rheumatic aortic insufficiency

“…11 Nevertheless, aortic cusp extension with short-time glutaraldehydetreated autologous pericardium 9 seems to yield the same satisfactory clinical results as those obtained by mitral leaflet enlargement with similarly treated autologous pericardium. 14 On the other hand, the literature concerning the use of fresh autologous pericardium in valvular surgery seems to be divided between those who observed progressive contracture and loss of pliability of fresh pericardium [15][16][17][18] and those who observed preserved pliability despite some degenerative changes and healing. [19][20][21][22] Frater and associates, 16,17 who reported that mitral and tricuspid leaflet extension with fresh pericardium results in thickening, retraction, and hyaline deposition, recognized that technical difficulties and consequent malalignment of the patch might be a contributing factor.…”

Outcomes of Totally Endoscopic Atrial Septal Defect Closure Using a Glutaraldehyde-Treated Autologous Pericardial Patch

“…Histological examination of the samples showed prominent degeneration associated with thickening and fibrotic change. 28 Chauvaud and colleagues reported their experience of 64 patients who underwent mitral valve repair using glutaraldehyde-treated autologous pericardium. 10 There were 6 patients who required reoperation during the follow-up period (6 months to 9 years after primary surgery).…”

“…28- 30 Ross and Olsen reported 11 cases of mitral valve repair using untreated autologous pericardium and very high reoperation rate (64%) in the 58 months after surgery. 28 They harvested the pericardial patches at the time of redo surgery. Histological examination of the samples showed prominent degeneration associated with thickening and fibrotic change.…”

REPLY: Optimal management of left ventricular free wall rupture considering the probability of rerupture

“…Ross and Olsen 3 used untreated autologous pericardium for mitral valve repair and reported prominent degeneration with thickening and fibrotic changes in the harvested pericardial patches during redo surgery. 3 Fukunaga and coworkers 4 reported that glutaraldehyde-treated autologous pericardium was severely calcified 5 years after mitral valve repair.…”
