ReviewAortic Valve Replacement With the Stentless Freedom SOLO Bioprosthesis: A Systematic Review
Section snippets
Material and Methods
A literature search of MEDLINE, EMBASE, and The Cochrane library (Fig 2) was done using the search terms “freedom SOLO” or “stentless SOLO.” The articles were selected independently by 2 reviewers (L.W. and W.L.) and are presented in Figure 2. After duplicates were removed, 97 titles were screened. Inclusion criteria for the title and abstract screening were “everything on the Freedom SOLO bioprosthesis.” After title screening, 20 titles were excluded (98% agreement). Seventy-seven abstracts
Clinical Outcomes
Table 1 and Table 2 show the clinical outcomes and follow-up of 2,185 patients with a Freedom SOLO. In 22 studies, the mean age was 74 years, concomitant procedures were performed in 39% of the patients, and the mean cross-clamp time for isolated AVR with the Freedom SOLO was 66 minutes. Seventy-seven patients (10%) underwent an operation for isolated aortic valve insufficiency (AoI). Mean European System for Cardiac Operative Risk Evaluation (EuroSCORE) was 8 and the mean logistic EuroSCORE
Comment
This systematic review shows that AVR with the Freedom SOLO is safe and feasible, with good prosthesis performance after a mean follow-up of 22 months (maximum, 83 months). Operative mortality of 3.5% and stroke rate of 1.1% in 2,185 patients with 39% concomitant procedures is comparable with other studies. Data from The Society of Thoracic Surgeons National Database shows an observed mortality of 3.0% and stroke in 1.5% in 141,905 isolated AVRs [3].

Hemodynamic and clinical performance of Solo stentless bioprosthetic aortic valves
2018, Revista Portuguesa de CardiologiaCitation Excerpt :The implantation technique proved to be simple and fast, with a similar mean cross-clamp time for isolated AVR (67 [59-85] min) to previous studies on the Solo valve.17 These times are shorter than those observed with earlier generations of stentless aortic valves (72-128 min) and also comparable to those reported for stented valves (50-67 min).17–20 In-hospital morbidity and mortality rates were low and comparable to previous studies, confirming the safety of FS/SS.7–10
Early hemodynamics and clinical outcomes of isolated aortic valve replacement with stentless or transcatheter valve in intermediate-risk patients
2017, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :Several studies report that the use of transcatheter valves in this particular subset of patients provides excellent hemodynamic and procedural results,15,25,26 albeit a comparison with the FS pericardial stentless bioprosthesis, implanted with a single supra-annular suture technique, has not been performed previously. Our experience showed that neither cross-clamp time nor periprocedural complications30 were increased in our FS cohort compared with conventional prostheses without a downside to surgical complexity, which may be attributable to the unique and relatively simple implantation technique afforded by FS, while providing the excellent hemodynamic performance expected of a stentless valve. Moreover, we found out that in intermediate-risk patients 30-day mortality was greater in the TAVR cohort compared with FS, with similar hemodynamic performance in the 2 groups.

2016, Seminars in Thoracic and Cardiovascular SurgeryCitation Excerpt :This leads to less prosthesis-patient mismatch, lower valvular gradients, and better postoperative outcomes.5 The Freedom SOLO (Sorin, Saluggia, and Italy) is a stentless bioprosthesis with an excellent hemodynamic profile and cross-clamp times that are equal to stented bioprostheses.6 Its stentless design and supra-annular implantation technique offers the largest possible effective orifice area.
