Description
Summary:Abstract Because of its favourable haemodynamic characteristics and easy implantability, Mitroflow aortic valve bioprosthesis has been the valve of choice for many surgeons in patients with small aortic annulus. Disappointingly, early structural valve deterioration and high transvalvular gradients have been reported mostly in older patients with small prostheses. Reimplanting a new stented prosthesis sutured in a narrow and damaged annulus is technically challenging and demanding mainly in high-risk patients. Valve-in-valve transcatheter aortic valve implantation has been proposed as a viable option; however, it presents significant limitations because of residual high transprosthetic pressure gradients and risk of coronary occlusion. We report a series of 8 patients, with medium-term follow-up, who underwent successful Perceval-S surgical sutureless aortic implant after the removal of a degenerated small Mitroflow valve. No early mortality occurred, but 1 patient died 4 months postoperatively due to gastrointestinal disease. No major complications occurred. Early and mid-term postoperative pressure gradients were low (mean gradients 13.1 ± 3.3 mmHg and 10.2 ± 3.8 mmHg, respectively). In operable patients with a degenerated Mitroflow valve, these favourable clinical and haemodynamic results suggest that the sutureless solution is a simple, valid and safer alternative to conventional redo valve replacement or to valve-in-valve transcatheter aortic valve implantation.
