Valve-preserving surgery on the bicuspid aortic valve.

Valve repair has emerged as an important intervention for the management of bicuspid aortic valve disease. This systematic review aims to assess the safety, efficacy and durability of bicuspid aortic valve repair. Initial searches yielded 682 abstracts, reduced by de-duplication to 370, of which 56 full papers were accessed and 30 met the inclusion criteria. Overall, 163 unique outcomes for bicuspid aortic valve-preserving surgery were reported on 280 occasions. Bicuspid aortic valve-preserving surgery exhibited low operative mortality (0.0-5.2%), excellent 5-year survival (82-100%) and 43-100% 5-year freedom from reoperation. Bicuspid aortic valve repair is safe and efficacious, but concerns regarding its durability necessitate further standardized outcome assessments.
