Abstract:
Surgery for aortic-valve endocarditis is still challenging, particularly in combination with destruction of the annulus. Freedom Solo (Solo) is a bovine stentless prosthesis for aortic valve replacement. It is implanted supra-annularly into the aortic wall with a single suture line, without requiring an 'intact' annulus. Thirteen patients received a Solo for endocarditis with annular destruction. Our results showed a low reinfection rate and no patient-prosthesis mismatch. Our contribution intends to show the feasibility of implantation also in case of complicated anatomical conditions, such as destruction of the annulus.
