Pulmonary arterial hypertension in congenital heart disease: Current perspectives and future challenges

Medical and scientific research in the field of pulmonary arterial hypertension (PAH) in adults with congenital heart disease (ACHD) has gradually become globalized, inclusive and collaborative over the past few years. The education of physicians, health administrators and patients on congenital heart disease (CHD), specifically in the field of PAH, is of paramount importance. It is also crucial for ACHD patients with PAH to be followed in tertiary centers and to benefit from a multidisciplinary approach. Shared care models dictate a closer collaboration between tertiary expert centers and local non-specialist services, as well as networking between expert physicians in CHD and PAH and geneticists/epidemiologists, with the inclusion of PAH-CHD patients in national and international registries with a detailed genotypic/phenotypic characterization.
