Lung transplantation is recognized as a treatment option for selected patients with end-stage lung disease and pulmonary vascular disorders. Overall, pulmonary hypertension (PH) is the second most frequent indication for children requiring lung transplantation. Pediatric lung transplantation can be complex; in PH patients timing for listing and the perioperative management can be particularly challenging making interdisciplinary collaboration with the referring PH team essential. Because pediatric patients typically have preserved cardiac index and exercise tolerance even with advanced disease, they should be referred early even if they do not meet the proposed criteria for listing by ISHLT published in 2015: NYHA functional class III or IV without improvement, cardiac index < 2 liters/min/m^2, mean right atrial pressure of > 15 mmHg. Bridging strategies with extracorporeal support should be determined at time of listing prior to transplantation anticipating the possibility of clinical deterioration. Bilateral lung transplantation using cardiopulmonary bypass to provide hemodynamics stability is the standard practice in pediatric centers. The immediate post-transplant period is characterized by dramatic normalization of PVR as well as changes in the RV and LV physiology and function which can be life-threatening. Induction, immunosuppression, prophylaxis and surveillance are not different from patients without PH. Overall, outcomes in pediatric lung and heart-lung transplant patients for PH are not different from those children undergoing lung or heart-lung transplant for other indications. In fact, long-term survival is superior in children with idiopathic PH compared to other diseases, there is also a dramatic improvement in quality of life in most recipients

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a serious health problem worldwide. In the pediatric population, currently available epidemiological data seem reassuring as the incidence of coronavirus disease 2019 (COVID-19) is much lower than in adults, with less critical cases and very few deaths. At present, there are no evidence-based studies on chest imaging in pediatric COVID-19. Chest X-rays showed non-specific findings and chest computed tomography (CT) exhibited similar, but fairly less severe CT changes compared to adult. Moreover, in approximately 50% of pediatric patients no correlation was found between chest CT imaging results and clinical characteristics. Lung ultrasound is rarely used, despite its unquestionable benefits as it can be performed at bed-side with a portable device, which minimizes virus transmission, is cheap and can be easily repeated. In conclusion, the chest imaging use in children, who are typically spared from severe infection, deserve recommendations different than adults also considering the increased risk of radiations exposure. In view of this, pediatric comparative studies among different chest imaging techniques, either less or more invasive, are urgently needed possibly after standardization of interpretation criteria of lung ultrasound.
