Toronto Stentless Porcine Valve® (T-SPV) (SJM)

As the first of the stentless valves, the T-SPV® has excellent hemodynamics and results in good left ventricle remodelling, postimplantation.[37,38] Recent studies based on long-term explants show tissue degeneration with calcification at 9-10 years.[38]

Butany et al.[38] reported on a series of 30 valves out of 350 implants, with a mean implant duration of 100.7 ± 27.8 months in which 90% of the valves displayed one or more of the following: tissue degeneration, cusp tears, calcification, or lipid insudation. Butany et al.[38] report a calcification rate of 76.7% (seen in 23 of 30 explanted valves from 332 total implants). This is likely due to the absence of antimineralization treatment.
