“…The haemodynamics of the FS bioprosthesis, in terms of transvalvular gradients and effective orifice areas indexed, have been shown to be at least as good as those of other routinely used stentless valves [2,12,13]. Moreover, it is interesting to note that, in our study, 24% of patients had a prosthesis size 21 or 19 and 61% a prosthesis size 23 or less.…”

Although porcine aortic valves or pericardial tissue mounted on a stent have made implantation techniques easier, these valves sacrifice orifice area and increase stress at the attachment of the stent, which causes primary tissue failure. Optimizing hemodynamics to prevent patient–prosthetic mismatch and improve durability, stentless bioprostheses use was revived in the early 1990s. The purpose of this review is to provide a current overview of stentless valves in the aortic position. Retrospective and prospective randomized controlled studies showed similar operative mortality and morbidity in stented and stentless aortic valve replacement (AVR), though stentless AVR required longer cross-clamp and cardiopulmonary bypass time. Several cohort studies showed improved survival after stentless AVR, probably due to better hemodynamic performance and earlier left ventricular (LV) mass regression compared with stented AVR. However, there was a bias of operation age and nonrandomization. A randomized trial supported an improved 8-year survival of patients with the Freestyle or Toronto valves compared with Carpentier–Edwards porcine valves. On the contrary, another randomized study did not show improved clinical outcomes up to 12 years. Freedom from reoperation at 12 years in Toronto stentless porcine valves ranged from 69% to 75%, which is much lower than for Carpentier–Edwards Perimount valves. Cusp tear with consequent aortic regurgitation was the most common cause of structural valve deterioration. Cryolife O’Brien valves also have shorter durability compared with stent valves. Actuarial freedom from reoperation was 44% at 10 years. Early prosthetic valve failure was also reported in patients who underwent root replacement with Shelhigh stentless composite grafts. There was no level I or IIa evidence of more effective orifice area, mean pressure gradient, LV mass regression, surgical risk, durability, and late outcomes in stentless bioprostheses. There is no general recommendation to prefer stentless bioprostheses in all patients. For new-generation pericardial stentless valves, follow-up over 15 years is necessary to compare the excellent results of stented valves such as the Carpentier–Edwards Perimount and Hancock II valves.

“…The haemodynamic performance of the Freedom Solo valve and other types of stentless valves has been well established, both in early and mid-term phases (23,24) . Although stentless valves initially had a similar technique of implantation as many other stentless or stented valves, the Sorin Pericarbon Freedom valve and Freedom Solo valve had an easier implantation technique involving 3 sutures or a single suture throughout the aortic annulus (8,9) .…”

Introduction:We aimed to determine whether thrombocytopaenia (TCP) is associated with postoperative complications in patients undergoing bioprosthetic aortic valve replacement.Patients and Methods: Clinical records of 39 consecutive patients undergoing bioprosthetic aortic valve replacement for aortic stenosis were reviewed. Patients were divided into 2 groups based on whether they had TCP or not within 7 days after the operation [TCP (+), 9 patients and TCP (-), 30 patients]. TCP was defined as a platelet count less than 50 × 10 9 /L.Results: Both the groups were similar with regard to baseline clinical characteristics and operative variables. Stentless bioprosthesis was used in 16 patients (41.02%). The use of Sorin Pericarbon Freedom was significantly more common in the TCP (+) group. Postoperative complications such as the removal time of the drainage tube, intensive care unit (ICU) stay and acute renal failure were significantly higher in the TCP (+) group. Overall, 30-day mortality occurred in 3 (7.7%) patients, and the difference between the groups was not statistically significant. Conclusion:Postoperative TCP may be associated with a substantial threat for the postoperative status of patients undergoing bioprosthetic valve replacement. The issue is still subject to further research until the exact mechanism underlying its occurrence is elucidated.
