Pulmonary valve disease is condition refers to any disorder of your heart's pulmonary valve, which is responsible for keeping blood from your heart flowing properly to your lungs. This is the valve separating the right ventricle (one of the chambers in the heart) and the pulmonary artery. The pulmonary artery carries oxygen-poor blood to the lungs.
Statistical analysis on pulmonary valve disease in United States resulted as the mean gestational age at SFLP was 21 (range, 18.7-24.3) weeks. Seven of sixteen (44%) recipients with abnormal pulmonary valve prior to SFLP survived. Six of the 16 (37.5%) recipient twins had documented absence of persistent pulmonary valve abnormalities at birth or at autopsy. Two (12.5%) of the 16 recipients (2.6% of the original cohort) had persistent pulmonary valve abnormalities at birth, requiring intervention.
