At Yale-New Haven Children's Hospital visionary research on building a living, working, heart valve for children with congenital heart disease is helping to revolutionize heart care for children. YNHCH pediatric surgeons Christopher Breuer, MD, and Toshiharu Shinoka, MD, have developed a novel procedure, approved by the FDA, that uses a patient's own cells to create a new, bioengineered heart valve. Yale-New Haven Children's Hospital is the only center in the United States to offer this potentially life-saving procedure to children with severe heart disease.
