Total calcification of an aortic homograft used as aortic root replacement.
A 66-year-old man presented with total calcification of a homograft used as aortic root replacement approximately 10 years previously. Reoperation consisted of complete dissection of the homograft and en-bloc replacement with a mechanical conduit. Despite careful dissection the right coronary ostium was disrupted requiring reconstruction by interposition of a saphenous vein segment. Reoperation for failure of homografts used as aortic root replacement represents a major technical challenge.
