Mending Children’s Hearts


Transcatheter Heart Valves for Children

Children born with congenital heart defects require frequent open-heart surgeries that prevent them from living their lives to the fullest.

PolyVascular provides the only non-surgical pulmonary valve and delivery system suitable for children as young as 2 years old. Our minimally invasive valve reduces the need for open heart surgery and enables kids to enjoy a healthy, normal lifestyle.

Effects of Congenital Heart Disease

Congenital Birth Defect

Most common birth defect: 2.4M in US

Infant Mortality

#1 Cause of birth defect related infant mortality

More Fatal than Cancer

Twice as many children die from CHD than all childhood cancers combined

Allograft Donor Pulmonary Valves

The Challenge

Current animal tissue valves often cause endocarditis, while human donor grafts may sensitize the child’s immune system. We address these limitations with our biocompatible, durable, polymer-based valve that is easy to manufacture at any size. The PolyVascular pulmonary valve is provided with an easy-to-use delivery system designed specifically for children that allows clinicians to safely position the valve percutaneously.
