متن کاملFactors affecting longevity of homograft valves used in right ventricular outflow tract reconstruction for congenital heart disease.
BACKGROUND Few studies have explored the long-term function of cryopreserved homograft valves used for reconstruction of the right ventricular tract (RVOT) in patients with congenital heart disease. METHODS AND RESULTS Among 205 patients receiving cryopreserved homografts for reconstruction of the RVOT between November 1985 and April 1999, the outcome of 220 homografts in 183 operative surviv...
متن کاملHomograft survival after tetralogy of Fallot repair: determinants of accelerated homograft degeneration.
AIMS Homografts are frequently implanted in patients with tetralogy of Fallot (TOF). However, the lifespan of homografts is shorter than that of graft recipients, thus making surgical re-intervention unavoidable. Therefore, to determine variables that could influence their survival, we retrospectively studied the survival pattern of homografts used to treat TOF. METHODS AND RESULTS Sixty-eigh...
متن کاملOutcome after homograft redo operation in aortic position.
OBJECTIVE Since 1992, homografts have been implanted in our institution. After initial sub-coronary implantation of the homograft, our preferred technique for aortic-valve replacement with homografts became root replacement, which poses a surgical challenge whenever redo procedures are necessary. The aim of the present study was to evaluate the outcome after homograft redo surgery, based on pro...
متن کاملRedo aortic root surgery for failure of an aortic homograft is a major technical challenge.
OBJECTIVE Aortic homografts offer many advantages over prosthetic valves. However, homograft dysfunction due to degeneration or infection may lead to reoperation. Aortic valve replacement in patients who have undergone previous aortic root replacement with an aortic homograft remains a technical challenge. To assess reoperation events a retrospective review was conducted. MATERIALS AND METHOD...
