Methods
We performed a retrospective review of Perceval S implantation at a single center between 2015 and 2018. After exclusion criteria, we compared 262 patients who underwent sutureless aortic valve (SLV) implantation with 394 patients who underwent standard sutured aortic valves (SAVR). Hospital cost data was reviewed, and risk adjustment, done by propensity score and inverse probability weighting, was used to compare outcomes.
