Background/Introduction
In order to develop a new surgical program based on recently developed technologies, companies often require a minimal volume of operations. Sutureless aortic bioprostheses were recently introduced in order to make the operation simpler, faster and more user friendly.
Aims/Objectives
The aim of this study is to review our results with the Edwards Intuity Elite sutureless bioprosthetic aortic valve.
Methods
The perioperative data of patients who underwent aortic valve replacement during the last year by sutureless bioprotheses (Edwards Intuity Elite, n = 7) were reviewed retrospectively and compared to those who received a conventional bioprostheses (Edwards Perimount Magna Ease, n = 7).
Results
Patients in the Intuity group were significantly older (76 vs. 64 years), but didn't differ significantly with regards to EuroSCORE-II or comorbidities. The operative times didn't differ significantly between groups, even though more patients in the Intuity group had concomitant procedures. No valvular and paravalvular leak or heart block were seen after the operation in both groups. Despite the median valve size being smaller in the Intuity group (21 vs. 25 mm), the postoperative gradients were significantly lower.
