Current classifications of pulmonary hypertension have contributed a great deal to our understanding of pulmonary vascular disease, facilitated drug trials, and improved our understanding of congenital heart disease in adult survivors. However, these classifications are not applicable readily to pediatric disease. The classification system that we propose is based firmly in clinical practice. The specific aims of this new system are to improve diagnostic strategies, to promote appropriate clinical investigation, to improve our understanding of disease pathogenesis, physiology and epidemiology, and to guide the development of human disease models in laboratory and animal studies. It should be also an educational resource. We emphasize the concepts of perinatal maladaptation, maldevelopment and pulmonary hypoplasia as causative factors in pediatric pulmonary hypertension. We highlight the importance of genetic, chromosomal and multiple congenital malformation syndromes in the presentation of pediatric pulmonary hypertension. We divide pediatric pulmonary hypertensive vascular disease into 10 broad categories.

Los miembros del Task Force pediátrico del Pulmonary Vascular Research Institute (PVRI, su sigla en Inglés) fueron conscientes de la necesidad de desarrollar una clasificación funcional de la hipertensión pulmonar en niños. La clasificación que se propone sigue el mismo patrón y utiliza los mismos criterios de la clasificación de la hipertensión pulmonar específica para adultos de Dana Point. Fue necesario incluir modificaciones para los niños, teniendo en cuenta que la edad, el crecimiento físico y la madurez influyen en la expresión funcional de la enfermedad. Es necesario definir el estado clínico del niño, pues ello facilita revisar la evolución del mismo en una forma consistente y objetiva a medida que él/ella crecen. Particularmente en los niños más jóvenes, se trató de incluir indicadores objetivos como el crecimiento, la necesidad de alimentos suplementarios y los registros de asistencia al colegio y a la guardería. Esto ayuda a monitorear la evolución clínica y la respuesta al tratamiento a través de los años y facilita el desarrollo de algoritmos de tratamiento en estos pacientes. Se presenta un artículo de consenso sobre una clasificación aplicable a los niños con hipertensión pulmonar que se discutió en la reunión anual del PVRI que se llevó a cabo en Panamá en febrero de 2011. The members of the Pediatric Task Force of the Pulmonary Vascular Research Institute (PVRI) were aware of the need to develop a functional classification of pulmonary hypertension in children. The proposed classification follows the same pattern and uses the same criteria as the Dana Point pulmonary hypertension specific classification for adults. Modifications were necessary for children, since age, physical growth and maturation influences the way in which the functional effects of a disease are expressed. It is essential to encapsulate a child's clinical status, to make it possible to review progress with time as he/she grows up, as consistently and as objectively as possible. Particularly in younger children we sought to include objective indicators such as thriving, need for supplemental feeds and the record of school or nursery attendance. This helps monitor the clinical course of events and response to treatment over the years. It also facilitates the development of treatment algorithms for children. We present a consensus paper on a functional classification system for children with pulmonary hypertension, discussed at the Annual Meeting of the PVRI in Panama City, February 2011.
Consenso sobre la clasificación de la enfermedad vascular pulmonar hipertensiva en niños: Reporte del task force pediátrico del Pulmonary Vascular Research Institute (PVRI) Panamá 2011

Las clasificaciones actuales de la hipertensión pulmonar han contribuido significativamente al conocimiento de la enfermedad vascular pulmonar, han facilitado ensayos farmacológicos y han mejorado nuestro conocimiento de las cardiopatías congénitas del adulto; sin embargo estas clasificaciones no son aplicables completamente a la enfermedad en el niño. La clasificación que aquí se propone se basa principalmente en la práctica clínica. Los objetivos específicos de esta nueva clasificación son mejorar las estrategias diagnósticas, promover la investigación clínica, mejorar nuestro conocimiento de la patogénesis, de la fisiología y de la epidemiología de la enfermedad y orientar el desarrollo de modelos de la enfermedad humana en el laboratorio y estudios en animales; también puede servir como un recurso docente. Se hace énfasis en los conceptos de maladaptación perinatal, alteraciones del desarrollo e hipoplasia pulmonar como factores causantes de la hipertensión pulmonar pediátrica; así mismo, en la importancia de los múltiples síndromes malformativos congénitos, genéticos y cromosómicos en la presentación de la hipertensión pulmonar pediátrica. La enfermedad vascular pulmonar hipertensiva en niños se divide en diez grandes categorías.
