Misalignment of pulmonary vessels with alveolar capillary dysplasia is a rare cause of persistent pulmonary hypertension of the newborn. Most of the reported cases have been sporadic. We present two consecutive affected siblings with this disorder. This is the fifth reported family occurrence of this condition. In addition to the pulmonary abnormality, one of our cases had duodenal atresia.

Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare, fatal, developmental lung disorder, which usually presents as persistent pulmonary hypertension of the newborn (PPHN) unresponsive to treatment. The authors present their own experience with three cases admitted during the last 15 years.

Abstract Alveolar capillary dysplasia with misalignment of the pulmonary veins is an uncommon disorder that affects the lung vasculature development in the neonatal period and leads to pulmonary hypertension. We describe two patients with alveolar capillary dysplasia associated with left-sided obstructive heart defects with two different genetic variants. Our cases highlight the importance of early recognition of this disease in the setting of persistent and supra-systemic pulmonary hypertension despite surgical correction of the associated lesions. Identification of these cases will facilitate the development of a multidisciplinary approach and provide guidance to the affected families.

Background: Pulmonary hypertension (PH) is a common complication in patients with Alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV), a severe congenital disorder associated with mutations in the FOXF1 gene. While the loss of alveolar microvasculature causes PH in ACDMPV patients, it is unknown whether increasing neonatal lung angiogenesis could prevent PH and right ventricular (RV) hypertrophy. Methods: We used echocardiography, RV catheterization, immunostaining and biochemical methods to examine lung and heart remodeling and RV output in Foxf1 WT/S52F mice carrying the S52F Foxf1 mutation (identified in ACDMPV patients). The ability of Foxf1 WT/S52F mutant embryonic stem cells (ESCs) to differentiate into respiratory cell lineages in vivo was examined using blastocyst complementation. Intravascular delivery of nanoparticles with a non-integrating Stat3 expression vector was used to improve neonatal pulmonary angiogenesis in Foxf1 WT/S52F mice and determine its effects on PH and RV hypertrophy. Results: Foxf1 WT/S52F mice developed PH and RV hypertrophy after birth. The severity of PH in Foxf1 WT/S52F mice directly correlated with mortality, low body weight, pulmonary artery muscularization and increased collagen deposition in the lung tissue. Increased fibrotic remodeling was found in human ACDMPV lungs. Mouse ESCs carrying the S52F Foxf1 mutation were used to produce chimeras via blastocyst complementation and to demonstrate that Foxf1 WT/S52F ESCs have a propensity to differentiate into pulmonary myofibroblasts. Intravascular delivery of nanoparticles carrying Stat3 cDNA protected Foxf1 WT/S52F mice from RV hypertrophy and PH, improved survival and decreased fibrotic lung remodeling. Conclusions: Nanoparticle therapies increasing neonatal pulmonary angiogenesis may be considered to prevent PH in ACDMPV.

Three full-term infants died in the first month of life with hypoplastic left heart syndrome (HLH) and persistent pulmonary hypertension (PPH). At postmortem examination, they were found to have alveolar capillary dysplasia with misalignment of pulmonary veins (ACD with MPV). The association of HLH syndrome, and ACD with MPV with intestinal malrotation and/or obstruction, is unique. Decreased blood flow in the ascending aorta in fetuses with left outflow tract obstruction might cause vasoconstriction of pulmonary arterioles to maintain cerebral perfusion. Vasoconstriction early during embryo-genesis might lead to decreased growth and development of alveolar capillaries and pulmonary veins. This results in pulmonary hypertension, and the arterial blood is forced to bypass the deficient capillary bed and can drain only via the anomalous bronchial veins.
