attention to the cardiac effect of pulmonary vascular disease, the cardiovascular comorbidities of COPD and the cardiovascular causes and effects of their acute exacerbation, the cardiorespiratory tropism of sarcoidosis or scleroderma, as well as the management of equivocal symptoms which can be of either cardiac or respiratory origin. The reader may ? nd overlaps between chapters. These are certainly red- dant if they express converging opinions while, in contrast, interesting if they express con? icting opinions resulting from the author's own experience and demonstrate that the use of imaging at the boundary between heart and lungs has not yet found its balance. The reader may also encounter chapters lacking suf? cient detail, such as the study of the cardio-pericardiac extent of neighbouring diseases (med- stinal, bronchopulmonary, pleural or even sub-diaphragmatic), or of therap- tic interactions between heart and lungs, a review of which alone would have merited a book of this size. We would like to express our profound gratitude to all the authors who c- tributed to this book, which represents a collective work of pioneers who have just opened the door to a new specialty.
