Since 1973 the World Symposia on Pulmonary Hypertension (WSPH) proceedings have summarised the scientific advances and future needs in this field through the efforts of multiple task forces, each focusing on a different aspect of pulmonary hypertension (PH) 1. The 6th WSPH comprised 124 experts, divided into 13 task forces, that began their work in January 2017 and presented their consensus opinions to an audience of 1376 participant attendees between February 27 and March 1, 2018 in Nice, France. A newly created task force dedicated to patients' perspectives, including representatives of patients' associations worldwide, was added for the 6th WSPH.
