In his monograph, Cassels provides an extensive discussion of the patent ductus arteriosus from almost every conceivable aspect. There are chapters dealing with ductal embryology, anatomy and histology, physiology, and clinical correlations. The author also deals with the patent ductus arteriosus in association with other cardiac defects, pulmonary hypertension, and hyaline membrane disease. All chapters have an informative bibliography.
Cassels book isn't easily read. In an apparent effort to provide all points of view concerning a topic, the author all too often leaves his reader with a complex disconnected picture. Unless the reader is relatively sophisticated concerning the subject, he will probably be left with an insufficient evaluation of the presented evidence and, thus, unable to come to a meaningful conclusion.
This book is of value to the individual with a particular interest in the patent ductus arteriosus. However, it is not recommended for the casual medical reader.
