Introduction
Bicuspid aortic valve (BAV) is one of the most common congenital diseases.(1–3) Some patients will develop an aneurysm or aortic insufficiency and require surgery. The traditional treatment modality for aortic root dilatation, with or without aortic dissection or aortic insufficiency, has been a composite valve-conduit (Bentall). (4) Patients with BAV tend to be younger than other patients undergoing treatment, and Bentall’s procedure involves a mechanical prosthesis. (5)
An alternative for such patients is aortic valve-sparing root replacement (AVSRR), which has been used with good results for three decades in patients with tricuspid aortic valves (6,7) but remains debated as an intervention for patients with BAV. (8,9) The aim of this study was to assess short- and mid-term clinical and safety outcomes with AVSRR, specifically Tirone’s procedure, in patients with BAV. (10–14)
