Abstract

The aortic homograft has become the replacement valve of choice in the treatment of complicated endocarditis involving native and prosthetic aortic valves. Complications are rare, typically involving chronic leaflet degeneration causing valvular insufficiency or rarely chronic calcific stenosis. We present a case in which functional stenosis of the homograft valve was caused by compression and distortion by blood transmitted directly from the left ventricle into a space between the homograft and an external cavity formed by a Dacron wrap. The latter had been placed to help control suture-line bleeding. This case presentation demonstrates an unusual cause of homograft failure and suggests that wrapping of a homograft conduit by native aorta or an external Dacron wrap is not a substitute for meticulous surgical technique to assure a hemostatic suture line.
