This case report describes a rare complication of aortic wall rarefaction
under Dacron prosthesis fitted around the dilated proximal
aorta. The wrap was performed under appropriate clinical
settings when both old and more recent clinical considerations
are applied. In patients undergoing cardiac surgery for other pathology
or with significant preoperative morbidity, this method
offers safe and durable treatment of mildly dilated ascending
aortic aneurysms, with little additional perioperative morbidity. It
is unknown whether this complication occurred as a result of
ascending aorta erosion from increased wall stress secondary to
BAV aortopathy or altered aortic dynamics because of the wrap
itself causing splinting of the aorta and loss of its dynamic ability
to respond to beat-to-beat differences pressure differences. Some
histological features of medial wall necrosis were present in the
specimen
