“…The preoperative demographics of patients in this study cohort were similar to other studies describing outcomes following AVR or MVR. [2][3][4][5][6][7][8] In the present study, younger patients who underwent bioprosthetic AVR were less likely to be female, have preoperative atrial fibrillation, and undergo concomitant CABG. Younger patients who underwent MVR were also less likely to require concomitant CABG.…”

“…1 Large cohort studies have indicated that excellent survival and freedom from valve-related complications, including reoperation, are associated with the use of a bioprosthesis for left heart valve replacement in patients older than 65 years. [2][3][4][5][6][7][8] Younger patients also may opt for a bioprosthesis at the time of valve surgery to avoid long-term oral anticoagulation, which is associated with hemorrhage and worse disease perception. 9 Recent North American data indicate that bioprostheses are increasingly used in patients less than 65 years of age who undergo aortic valve replacement (AVR) or mitral valve replacement (MVR).…”

“…Indeed, it remains unclear as to exactly how long a bioprosthesis may last when it is implanted in a patient in his or her fifth or sixth decade of life. [2][3][4][5][6][7][8][13][14][15] Accurate reoperation information would be important for patients who present for valve replacement surgery at a young age, as well as for the physicians who treat them.…”

Background-Evidence supporting the use of bioprostheses for heart valve replacement in young adults is accumulating.However, reoperation data, which may help guide clinical decision making in young patients, remains poorly defined in the literature. Methods and Results-We examined the need for reoperation in 3975 patients who underwent first-time bioprosthetic aortic valve replacement (AVR) (nϭ3152) or mitral valve replacement (MVR) (nϭ823). There were 895 patients below the age of 60 years at bioprosthesis implant (AVR, nϭ636; MVR, nϭ259

“…The SJM Epic and the Epic Supra are both based on the design of the Biocor valve, which has a documented 20-year long-term durability. 16 Its design consists of a triple composite construction with matched individual leaflets. The leaflet tissue is fixed under low pressure in glutaraldehyde to promote retention of collagen crimp and elasticity, before applying the Linx anticalcification treatment.…”

Background— Complete supraannular placement of an aortic bioprosthesis is one approach to optimize the hemodynamic result of an aortic valve replacement. It is achieved with the combination of a special valve design and the supraannular sewing technique with noneverted mattress sutures. We evaluated 5 bioprostheses designed for complete supraannular placement to assess potential hemodynamic differences caused by factors (eg, valve material) other than implantation position. Methods and Results— In 336 patients (mean age, 72.0±7.1 years; 143 women), hemodynamics including mean pressure gradients, effective orifice areas, and indices and incidence of patient-prosthesis mismatch were evaluated 6 months after surgery. Annulus diameter was measured during surgery. Patients received the Carpentier Edwards Perimount Magna (Magna, n=169), the Medtronic Mosaic (Mosaic, n=46), the Mosaic Ultra (Ultra, n=17), the SJM Epic Supra (Epic, n=46), and the Sorin Soprano (Soprano, n=58). For small annulus sizes (<23 mm), the mean pressure gradients of the Magna (11.82±4.8 mm Hg) were significantly lower than the Mosaic (16.04±6.1 mm Hg) and the Ultra (22.0±4.1 mm Hg), and the Soprano (13.3±5.2 mm Hg) was hemodynamically superior to the Ultra. For medium (23 to 24 mm) and large (>24 mm) annulus sizes, the mean pressure gradients of the Magna were lower than the Epic (10.0±3.5 mm Hg versus 14.9±6.4 mm Hg; 9.9±4.0 mm Hg versus 18.6±12.7 mm Hg). Furthermore, in patients with large annulus size, the mean pressure gradients of the Soprano (11.4±3.8 mm Hg) were lower compared with the Epic (18.5±12.7 mm Hg). Severe patient-prosthesis mismatch was observed more frequently in patients with the Mosaic (12/46; 26.1%) and the Ultra (3/17; 17.6%) prostheses. Conclusions— Complete supraannular placement cannot prevent high pressure gradients or patient-prosthesis mismatch thoroughly, but the choice of a bovine prosthesis can optimize hemodynamic performance.
