Key result
Reoperation for total calcification of an aortic homograft 10 years post-implantation required complete dissection, en-bloc replacement with a mechanical conduit, and right coronary ostium reconstruction.
Case Report (n=1)
Reoperation for a heavily calcified aortic homograft is technically challenging and may require complex reconstruction such as coronary ostium repair.
Alerts to technical demands of late homograft reoperation; leaves open optimal graft choice and surveillance strategies.
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.

Ravenni et al. (2010) conducted a case report in Total calcification of an aortic homograft (n=1). Reoperation with complete dissection and en-bloc replacement with a mechanical conduit was evaluated. Reoperation for total calcification of an aortic homograft 10 years post-implantation required complete dissection, en-bloc replacement with a mechanical conduit, and right coronary ostium reconstruction.
