Abstract
Primary pulmonary vein stenosis (PPVS) represents a rare but emerging, often progressive heterogeneous disease with high morbidity and mortality in the pediatric population. Although our understanding of PPVS disease has improved markedly in recent years, much remains unknown regarding disease pathogenesis, distinct disease phenotypes, and patient- and disease-related risk factors driving the unrelenting disease progression characteristic of PPVS. In the pediatric population, risk factors identified in the development of PPVS include an underlying congenital heart disease, prematurity and associated conditions, and an underlying genetic or congenital syndrome. Continued improvement in the survival of high-risk populations, coupled with ongoing advances in general PPVS awareness and diagnostic imaging technologies suggest that PPVS will be an increasingly prevalent disease affecting pediatric populations in the years to come. However, significant challenges persist in both the diagnosis and management of PPVS. Standardized definitions and risk stratification for PPVS are lacking. Furthermore, evidence-based guidelines for screening, monitoring, and treatment remain to be established. Given these limitations, significant practice variation in management approaches has emerged across centers, and contemporary outcomes for patients affected by PPVS remain guarded. To improve care and outcomes for PPVS patients, the development and implementation of universal definitions for disease and severity, as well as evidence-based guidelines for screening, monitoring, cardiorespiratory care, and indications for surgical intervention will be critical. In addition, collaboration across institutions will be paramount in the creation of regionalized referral centers as well as a comprehensive patient registry for those requiring pulmonary vein stenosis.

Abstract
Pulmonary vein stenosis (PVS) is a rare condition that has been linked to prematurity and congenital heart disease (CHD). Despite these associations, treatment options are limited and outcomes are guarded. We investigated differences in PVS outcomes based on the presence of CHD and prematurity, and risk factors for mortality or lung transplantation in PVS. Single-center retrospective cohort study of patients diagnosed with PVS between January 2005 and May 2016 and identified by ICD codes with chart validation. Cox proportional hazard models assessed risk factors for the composite outcome of mortality or lung transplantation. Ninety-three patients with PVS were identified: 65 (70%) had significant CHD, 32 (34%) were premature, and 14 (15%) were premature with CHD. Sixty-five (70%) underwent a PVS intervention and 42 (46%) underwent ≥2 interventions. Twenty-five subjects (27%) died or underwent lung transplant 5.8 months (interquartile range [IQR] 1.1, 15.3) after diagnosis. There was no difference in age at diagnosis or mortality based on presence of CHD or prematurity. PVS diagnosis before age 6 months and greater than 1 pulmonary vein affected at diagnosis were associated with higher mortality (hazards ratio [HR] 3.4 (95% confidence interval 1.5, 7.5), P = 0.003, and HR 2.1 per additional vein affected (95% confidence interval 1.3, 3.4), P = 0.004, respectively). Survival in children with PVS is poor, independent of underlying CHD or prematurity. Younger age and greater number of veins affected at diagnosis are risk factors for worse outcome. Understanding causal mechanisms and development of treatment strategies are necessary to improve outcomes.

Abstract
OBJECTIVE To quantify outcomes of infants (<1 year of age) diagnosed with pulmonary vein stenosis (PVS). STUDY DESIGN MEDLINE (PubMed), Scopus, and Web of Science were searched through February 1, 2017, with no language restrictions. Publications including infants diagnosed with primary PVS, defined as the absence of preceding intervention(s), were considered. The study was performed according to Meta-analysis of Observational Studies in Epidemiology guidelines, the Systematic Reviews, and Meta-Analysis checklist, and registered prospectively. The quality of selected reports was critically examined. Data extraction was independently performed by multiple observers with outcomes agreed upon a priori. Data were pooled using an inverse variance heterogeneity model with incidence of mortality the primary outcome of interest. RESULTS Forty-eight studies of 185 infants were included. Studies were highly diverse with regards to the participants, interventions, and outcomes reported. The median (range) age at diagnosis was 5.0 (0.1-11.6) months. Pooled mortality was 58.5% (95% CI 49.8%-67.0%, I2 = 21.4%). We observed greater mortality incidence among infants with 3 or 4 vein stenoses than in those with 1 or 2 vein stenoses (83.3% vs 36.1%; P < .01). We observed greater mortality among infants with bilateral than unilateral disease (78.7% vs 26.0%; P < .01). CONCLUSIONS Studies of primary PVS during infancy are highly variable in their methodological quality and estimates of clinical outcomes; therefore, estimates of prognosis remain uncertain. Multicenter, interdisciplinary collaborations, including alignment of key outcome measurements, are needed to answer questions beyond the scope of available data.

Abstract
Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of failed circulatory adaptation at birth due to delay or impairment in the normal fall in pulmonary vascular resistance (PVR) that occurs following birth. The fetus is in a state of physiological pulmonary hypertension. In utero, the fetus receives oxygenated blood from the placenta through the umbilical vein. At birth, following initiation of respiration, there is a sudden precipitous fall in the PVR and an increase of systemic vascular resistance (SVR) due to the removal of the placenta from circulation. There is dramatic increase in pulmonary blood flow with a decrease in, and later reversal of shunts at the foramen ovale and ductus arteriosus. The failure of this normal physiological pulmonary transition leads to the syndrome of PPHN. PPHN presents with varying degrees of hypoxemic respiratory failure. Survival of infants with PPHN has significantly improved with the use of gentle ventilation, surfactant and inhaled nitric oxide (iNO). PPHN is associated with significant mortality and morbidity among survivors. Newer agents that target different enzymatic pathways in the vascular smooth muscle are in different stages of development and testing. Further research using these agents is likely to further reduce morbidity and mortality associated with PPHN.

Abstract
Pulmonary hypertension is associated with diverse cardiac, pulmonary, and systemic diseases in neonates, infants, and older children and contributes to significant morbidity and mortality. However, current approaches to caring for pediatric patients with pulmonary hypertension have been limited by the lack of consensus guidelines from experts in the field. In a joint effort from the American Heart Association and American Thoracic Society, a panel of experienced clinicians and clinician-scientists was assembled to review the current literature and to make recommendations on the diagnosis, evaluation, and treatment of pediatric pulmonary hypertension. This publication presents the results of extensive literature reviews, discussions, and formal scoring of recommendations for the care of children with pulmonary hypertension.

Abstract
Pulmonary venous stenosis is rare and is most commonly found in association with cardiac malformations. Recent studies have associated pulmonary venous stenosis with prematurity, especially with bronchopulmonary dysplasia, although no such case has been documented at autopsy. We report the case of a 26-week-gestation infant who required ventilation at birth and who, among other complications, developed chronic lung disease of prematurity by the age of 3 months. Imaging showed suprasystemic right-sided pressures and pulmonary venous stenosis. Despite aggressive management of respiratory status and surgical marsupialization of stenoses, the infant expired after 3 weeks. At autopsy, 3 of 4 pulmonary veins showed a fibrous ridge obstructing atrial ostia with otherwise normal anatomy. The lungs showed bronchopulmonary dysplasia, pulmonary hypertensive vascular changes, and features of venous obstruction. Pulmonary venous stenosis and bronchopulmonary dysplasia in premature infants may be pathogenetically related. Coincidence of these diseases is likely underrecognized, and careful cardiac examination in these patients is warranted.

Abstract
BACKGROUND Pulmonary vein stenosis is a rare cause of pulmonary hypertension, with variable onset and presentation. One or more of the four pulmonary veins can be primarily or secondarily affected. A five-month-old girl presented with respiratory distress, lethargy and cyanosis requiring intubation. METHODS Echocardiography showed right ventricular dilation, a right ventricular systolic pressure of 97 mmHg, decreased ejection fraction and turbulent flow at the left atrium. Cardiac catheterization revealed stenosis of the left-sided pulmonary veins, for which she underwent a Coles procedure. RESULTS Postoperatively, there was a transient improvement in the patient's pulmonary hypertension but she subsequently deteriorated. Her prognosis was considered bleak, and a decision was made with the family to withdraw care. CONCLUSION Pulmonary vein stenosis is a rare cause of pulmonary hypertension, and is associated with significant morbidity and mortality. Surgical intervention may be of benefit in selected cases. It stands to reason that any treatment will have the best chance of success if completed before the pulmonary hypertension becomes fixed. Early diagnosis depends on a high index of clinical suspicion.

Abstract
Major advances have been made in the understanding and treatment of pulmonary hypertension in the last few years. Without treatment (medication) for idiopathic pulmonary arterial hypertension, which is a rare and potentially fatal condition, the survival time is only about 3 years after diagnosis. However, if pulmonary hypertension is secondary to other causes such as congenital heart disease, it is possible to survive for 30 years or more without treatment. The condition can affect children at any age, from fetal life to adulthood. Patients with pulmonary hypertension can present to the respiratory pediatrician with unresponsive asthma, to the neurologist with faints, or to the general pediatrician with failure to thrive. Over the last few years there have been significant developments in the available therapy for managing this complicated disease. There is now a generally recognized ladder of long-term therapy for chronic pulmonary hypertension. Treatment can start with oxygen at home at night or even during the day. Next is the use of oral phosphodiesterase inhibitors, mostly type V, such as sildenafil, which enhance endogenous nitric oxide. More potent are the endothelin receptor antagonists and the most potent are the prostanoids, especially epoprostenol, which is given by constant intravenous infusion. In addition to interventional catheterization with atrial septostomy, these agents have improved the prognostic outlook. This article reviews the current knowledge about the etiology, investigation, and treatment of children with pulmonary hypertension in the clinical setting.

Abstract
Idiopathic pulmonary arterial hypertension is a rare and potentially fatal condition. Without treatment, survival is only approximately 2.8 years from diagnosis. However, if the pulmonary hypertension is secondary to other causes, especially to congenital heart disease, it is possible to survive for 30 years or more without treatment. In recent years, remarkable progress has been made, risk factors have been identified and improved imaging techniques, including echocardiography, computer tomography and magnetic resonance imaging, are available. The condition can affect children at any age from fetal life through to adulthood. Patients can present to the respiratory pediatrician with unresponsive asthma, to the neurologist with faints or to the general pediatrician with failure to thrive. Over the last few years there have been significant developments in the available therapy for managing this complicated disease, which have improved the prognostic outlook, such as oral bosentan and sildenafil, intravenous epoprostenol and interventional catheterization with atrial septostomy. This article reviews the current knowledge about causation, investigation and treatment of children with pulmonary hypertension in the clinical setting.

Abstract
Pulmonary hypertension (PHT) is a well recognised feature of untreated congenital heart disease. This article will review the causes, known mechanisms, appropriate investigations and current therapies for PHT. The reader will understand the difference between PHT due to high pulmonary blood flow and PHT that is due to high pulmonary vascular resistance. The former is best treated by surgical or catheter intervention, whereas for the latter (Eisenmenger syndrome) only palliation is possible with medication or transplantation. Echocardiography and electrocardiography (ECG) should be performed in any child where there is a possibility of pulmonary hypertension, especially with long standing chronic lung disease and minor left to right shunt. Often these children may have dual pathology and their investigation and management may be a complex interaction between cardiac and respiratory therapists. New treatments and new techniques of assessment are now available and this may lead to improved recognition of PHT and prevention of long term disability as a result.

Abstract
We report the case of an infant born prematurely at 27 weeks gestational age with life-threatening pulmonary hypertension crisis as a result of left upper pulmonary vein stenosis. Surgical treatment consisted of a lobectomy, which is a safe and effective procedure. Evidence strongly suggests that the venous stenosis may have resulted from hypertonic drugs infused through an umbilical catheter facing the upper left venous-atrial junction.

Abstract
A variety of pulmonary vascular disorders, such as hemangiomatosis, telangectasia, and veno-occlusive disease, may be involved in the pathogenesis of interstitial lung diseases. We describe the case of a girl with recurrent bacterial pneumonia and progressive interstitial fibrosis affecting the right lung. Morphologic evaluation of the lung biopsy showed structural changes of the vessel walls suggesting pulmonary hypertension. The echocardiogram showed the presence of centripetal blood flow in the right pulmonary artery from the periphery of the lung to the heart. A selective right angiography demonstrated the presence of pulmonary venous obstruction at the veno-atrial junction, successfully treated by endovascular stent implantation during cardiac catheterization.
