Aortic Disease and Treatment Approaches

Durability of sutureless aortic bioprosthetic valves remains a major issue. The aim of this study was to assess structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) of the Perceval bioprosthesis using the new proposed standardized definitions.All patients who underwent aortic valve replacement with sutureless Perceval S prostheses up to September 2016 were included. Clinical and echocardiographic follow-up was performed. New standardized definitions were used to assess the durability of sutureless bioprosthetic valves. From 2013 to 2016, 214 patients were included.The mean age and EuroSCORE II were 79 years and 2.74. Thirty-day mortality was 0.47%. The survival rate was 96.8%, 88.1% and 85.7% at 1, 3 and 4 years, respectively. The median echocardiographic follow-up was 3.28 years. The mean pressure gradient was 11.3 mmHg. No cases showed evidence of severe SVD, 17 patients had moderate SVD with a mean pressure gradient of 24 mmHg and 8 patients had definite late BVF. The incidence of moderate SVD and BVF at 4 years was 8.8% and 2.9%, respectively.Mid-term follow-up to 6.3 years after aortic valve replacement with the Perceval bioprosthesis documents favourable haemodynamic and clinical outcomes and low rates of SVD and BVF.
