Key result
The Bentall procedure with a mechanical prosthetic valve was successfully performed in a 24-year-old man with a unicuspid aortic valve, resulting in an uneventful course and improved cardiac function at one year.
Why the study?
A high percentage of patients with a unicuspid aortic valve require cardiac surgery due to aortic stenosis or regurgitation, and it is sometimes difficult to discriminate from a bicuspid valve.
Case Report (n=1)
The Bentall operation with a mechanical prosthetic valve can be successfully performed in young patients with unicuspid aortic valve and annulo-aortic ectasia when valve-sparing surgery is not feasible.
Supports feasibility of mechanical Bentall in young unicuspid aortic valve patients; leaves open durability and comparative outcomes.
A high percentage of patients with a unicuspid aortic valve require cardiac surgery, because it always induces aortic stenosis or regurgitation. It is sometimes difficult to discriminate it from a bicuspid valve. Here, we report a case of a young patient with severe aortic regurgitation and aortic root enlargement caused by the unicommissural form of unicuspid aortic valve. An aortic valve-sparing operation could not be performed because of his special morphology, and it was thought that sufficient durability could not be obtained postoperatively. The Bentall operation was successfully performed with a mechanical prosthetic valve. His postoperative course was uneventful.

Yu et al. (2019) conducted a case report in Unicuspid aortic valve with annulo-aortic ectasia (n=1). Bentall procedure with a mechanical prosthetic valve and hemi-arch replacement was evaluated on Postoperative clinical course and cardiac function. The Bentall procedure with a mechanical prosthetic valve was successfully performed in a 24-year-old man with a unicuspid aortic valve, resulting in an uneventful course and improved cardiac function at one year.
