Surgical aortic valve replacement (AVR) is the therapy of choice for severe symptomatic disease and has become a safe procedure, reflecting not only advances in intra- and postoperative care, but also improvements in prosthetic valve design and technology.<a class="elsevierStyleCrossRefs" href="#bib0125"><span class="elsevierStyleSup">1,2</span></a> The ideal prosthetic valve should have low transvalvular gradients, maximum effective orifice area (EOA) and minimum patient-prosthesis mismatch (PPM), mimicking the anatomy and hemodynamic profile of healthy native valves. Moreover, it should be easy and safe to implant, durable, resistant to infection and have low thrombogenic risk. However, the search for the perfect artificial valve continues.<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">3</span></a></p><p id="par0070" class="elsevierStylePara elsevierViewall">Stentless bioprosthetic aortic valves, without an obstructive stent or a rigid suture ring, have proven excellent hemodynamic performance, similar to homografts. This improved hemodynamic profile is also associated with survival benefit, although this may be at the expense of a greater risk of structural valve deterioration (SVD) and need for reoperation.<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">4</span></a> The first widely used stentless valve, the Toronto SPV, had low long-term durability, generally attributed to its stentless design, although it could also be related to its porcine origin.<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">5</span></a> As with other early-generation stentless valves, implantation was technically demanding.<a class="elsevierStyleCrossRef" href="#bib0150"><span class="elsevierStyleSup">6</span></a> The Freedom Solo (FS) and Solo Smart (SS) biological valves (Sorin Group, Saluggia, Italy) emerged in response to these technical challenges and have been in clinical use since 2004. These are third-generation stentless valves (the Smart is the same model with a different holder) with supra-annular implantation and a single suture line. The valves are manufactured from bovine pericardial tissue detoxified in homocysteic acid, which may reduce structural valve deterioration. As they are stentless, supra-annular and easily adaptable to the aortic root, they allow larger valve sizes and EOA than an equivalent stented valve, favoring laminar flow.<a class="elsevierStyleCrossRefs" href="#bib0155"><span class="elsevierStyleSup">7,8</span></a></p><p id="par0075" class="elsevierStylePara elsevierViewall">High-volume centers have begun publishing their experience with these bioprostheses, confirming them as a safe and reliable alternative for AVR, but the available clinical data are limited and need to be supported by larger patient series and longer follow-up times.<a class="elsevierStyleCrossRefs" href="#bib0165"><span class="elsevierStyleSup">9–12</span></a></p><p id="par0080" class="elsevierStylePara elsevierViewall">The objective of this study is to report the hemodynamic profile and the short- and medium-term outcomes of FS/SS stentless bioprosthetic valves implanted at our center during a six-year period.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0075">Methods</span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0080">Study design and setting</span><p id="par0085" class="elsevierStylePara elsevierViewall">We performed a retrospective, longitudinal and descriptive study.

Three 4-0 polypropylene sutures were placed in a supra-annular position at the nadir of each sinus and passed through the Solo valve. Thereafter, the valve was parachuted into the aortic root and tied with sutures running continuously 1 mm above the annulus. The sutures were passed out of the aorta at the level of the commissures and tied with the suture from the adjacent sinus. Immediate outcome was assessed by intraoperative transesophageal echocardiography. All patients underwent our center's standard anesthetic, surgical and postoperative care procedures.
