The cardiopulmonary system: research and training opportunities.

The new biology has the potential to provide mechanistic insights into the causes and progression of complex cardiopulmonary diseases such as congenital heart disease and bronchopulmonary dysplasia. Such research requires collaborative investigation supported by sophisticated infrastructures and core facilities. Translating basic observations to clinical outcomes will require networks for collaborative translational research. The research initiatives require excellently trained and motivated clinician-scientists, but there are numerous barriers to the training and support of clinician-scientists in cardiology and neonatology.
