A year has now passed since the launch of Pulmonary Circulation, a journal dedicated to the clinical and basic science of the pulmonary vasculature. The birth of any new journal is a fragile affair, and whether it truly succeeds is judged by a number of factors. It remains to be seen where the journal finds its place when judged by the hard indices of impact factor and citations. This may take another year and four further issues, though we are quietly confident that the quality of reviews and original articles we have published will be reflected in those figures. Another important measure of success of a specialist journal is the reception it receives from the clinical and scientific community that willed it into being. This reception has been loud and clear: The journal is fulfilling its mission of providing a high-quality forum for some of the best ideas, authoritative reviews, and original observations in the field of pulmonary vascular disease. This will serve to accelerate the generation and analysis of knowledge, ultimately leading to a greater understanding of disease mechanisms and better treatments for patients.
