Background and aim of the study: Because of the design and specific implantation technique of the stentless Freedom SOLO bioprosthesis, patient selection is crucial. The aim of the study was to discuss the contraindications to this prosthesis based on the authors’ implant experience.
Methods: Between April 2005 and February 2015, one surgeon at the authors’ center performed 292 aortic valve replacements using a bioprosthesis, with the initial intention of implanting a SOLO valve in every patient. A search was conducted for all of these patients and data collected on whether a SOLO valve was used, or not.
Results: A SOLO valve was implanted in 238 patients (82%), and a stented bioprosthesis in 54 (18%). The
predominant reasons not to implant a SOLO valve were asymmetric commissures (26%) and a large aortic annulus (24%). Only one patient had structural valve deterioration, and none of the patients had to undergo reoperation because of aortic valve insufficiency or paravalvular leakage.
Conclusion: Asymmetric commissures, large aortic annulus (>27 mm), calcified aortic sinuses, dilated sinotubular junction, aberrant location of coronary ostia and whenever the stent of a stented bioprosthesis is useful, were contraindications to implant a SOLO valve. When these contraindications were taken into account, a very good durability could be achieved with the SOLO valve during mid-term follow up.
