Study summary

Prospective, single-arm, multi-center study to evaluate safety and effectiveness of the Autus Size-Adjustable Valve in pediatric patients aged 18 months to 16 years requiring surgical pulmonary valve replacement. The Autus Valve may be expanded pre-implant to match the subject's body size. Subjects will be evaluated prior to the Autus Valve implant procedure, immediately post-implant, at hospital discharge, 30 days, 6 months, and annually through 10 years.

The Autus Valve may be expanded post-implant via transcatheter balloon dilation to accommodate growth of the subject. In subjects who undergo a post-implant valve expansion, follow-up will continue for a minimum of 1 year after the post-implant valve expansion procedure.
