    Abstract:
    Aortic valve replacement by bioprosthesis is increasingly being used. Among these, stentless bioprosthesis is becoming a valid choice due to its potential hemodynamic improvement. The Sorin Freedom SOLO stentless aortic valve (FS) (Sorin Biomedica Cardio, Saluggia, Italy) is widely used, with initial and midterm promising results. It is designed to be deployed in a straightforward manner in the supraannular position with a single running suture due to its reproducible implantation technique. Few specific valve-related complications, such as transient thrombocytopenia or rare thrombotic events, are known. Our experience, after the implantation of 33 Freedom SOLO, suggests that using the classical implantation technique, the noncoronary sinus adopts a conformation that increases the difficulty of the implant. Besides, it could also be distorted increasing the risk of periprosthetic leakage and hypothetically becoming the origin of thrombus. We present an easy and safe variation in the implantation technique of the FS that decreases the technical difficulty of the implantation, reduces the risk of periprosthetic leakage, and may additionally reduce the risk of thrombosis.
