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.
