Pediatric pulmonary hypertension (PH) has emerged as a major clinical problem throughout the world. This problem has grown for two reasons: (a) increased awareness of the strong impact of PH on short and long‐term outcomes in more diverse diseases, which has led to an increase in screening and diagnostic evaluations; and (b) the availability of PH‐specific drug therapies leading to improved survival. We have the honor of leading off this special issue of Pediatric Pulmonology with an overview of the many faces of PH in neonates, infants, children, and adolescents, with particular emphasis on the importance and need for pediatric pulmonologists to develop a greater understanding of PH. While a large proportion of leaders in adult PH are pulmonologists, pediatric cardiologists have dominated the field in children with PH. With growing awareness of the importance of PH in dictating outcomes of many childhood lung diseases and the critical contribution of respiratory problems to outcomes of children with many forms of PH, it is clear that pediatric pulmonary specialists must become more knowledgeable and engaged in PH‐related diseases. As reflected by the development of PH teams at many medical centers, it is evident that optimal care for these patients requires the collaboration of pediatric pulmonologists with pediatric cardiologists, intensivists, neonatologists, pharmacists, and others. As a result, the goal of this supplemental issue of Pediatric Pulmonology is to highlight and provide updates on key aspects of this important clinical field of pediatric PH.
