Our experience shows that root replacement with Freestyle stentless bioprostheses in patient with VE, is associated with low rates of early and mid-term mortality, good haemodynamic performance and low rates of valve-related morbidity as well as low recurrence of infection.

Endovascular stent-graft repair is emerging as the treatment of choice for complicated type B aortic dissection. In this report we describe a patient who presented with type B aortic dissection involving a right-sided aortic arch (RAA), a rare congenital vascular anomaly. The initial aggressive medical treatment proved unsuccessful due to false aneurysm expansion. Given the greater complexity of conventional surgical repair and the limited experience with this rare malformation, endovascular repair was preferred and successfully performed. We report the first case of endovascular repair of type B dissection involving RAA, confirming that endovascular treatment is technically feasible also when the dissection involves this unusual vascular malformation.

A less pronounced graft oversizing is needed to achieve normal-range sinuses size when using a Valsalva graft, the ideal theoretical graft oversizing was +7mm for a standard graft and +3mm for the Valsalva graft, our normograms can be helpful in selecting a proper graft size when performing a valve-sparing aortic procedure.
