Homograft implantation for aortic valve replacement since 15 years – results and follow-up

Outcome after homograft redo operation in aortic position

“…However, it has been apparent in recent years, as our article has shown, that the long-term durability does not seem to be superior compared with biological xenoprostheses [16,17], due to chronic degeneration of the HGs, leading to fibrosis and calcification along with intense root calcification (Fig. 5).…”

Homografts in aortic position: does blood group incompatibility have an impact on patient outcomes?†

“…The preservation technique was developed from fresh-wet valves to cryopreserved homografts that underwent sterilization with an antibiotic cocktail [4]. The implantation technique was also improved from the subcoronary implantation to root replacement with reimplantation of the coronary arteries [16]. The use of pulmonary homografts in aortic position showed an impaired outcome in the long-term follow-up leading to the termination of using those grafts [17].…”
