Aortic valve replacement using the Freedom SOLO stentless bioprosthesis: clinical and haemodynamic performance in 625 patients at medium-term follow-up.

Objectives: Our goal was to analyse the haemodynamic and clinical results after implantation of the Freedom SOLO stentless aortic valve replacement by assessing the immediate postoperative results regarding mortality, discharge echocardiographic gradients and reoperation rates and by evaluating these results in the medium term.

Methods: This study was designed as a single-centre retrospective observational trial. Clinical and echocardiographic data were collected retrospectively from 625 patients undergoing an aortic valve replacement using the Freedom Solo stentless valve (LivaNova, London, UK) at the Sint-Jan Hospital, Bruges, between May 2009 and May 2017.
