Abstract
"This is not the heart; this is the lung." Who among paediatric pulmonologists has never faced this situation with a cardiologist? Joking aside, discussions for some cases may be tricky and our common ultimate goal is always to provide the best care to the patients and their families. In this review, we will focus on the links between the heart, or more widely the cardiovascular system, and bronchopulmonary dysplasia, in order to determine if this quote is a myth or a maxim.
