Key result
Modified Sorin Freedom SOLO implantation technique linked to reduced technical difficulty and complication risks.
Why the study?
The classical implantation technique of the Sorin Freedom SOLO stentless aortic valve may increase technical difficulty and risk of complications such as periprosthetic leakage and thrombosis.
Does a variation in the implantation technique of the Sorin Freedom SOLO stentless aortic valve reduce technical difficulty and risk of complications compared to the classical technique?
Does a variation in the implantation technique of the Sorin Freedom SOLO stentless aortic valve reduce technical difficulty and risk of complications compared to the classical technique?
A modified implantation technique for the Sorin Freedom SOLO stentless aortic valve may reduce technical difficulty and the risk of periprosthetic leakage and thrombosis.
May ease stentless valve implantation; leaves open comparative safety versus classical technique.
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.

Permanyer et al. (2011) studied Aortic valve replacement (n=33). Variation in implantation technique vs. Classical implantation technique was evaluated. In an experience of 33 implantations, a variation in the implantation technique of the Sorin Freedom SOLO stentless aortic valve was presented to decrease technical difficulty and complication risks.
