Opposing forces and a river into a lake: Relevance to coronary hemodynamics in Kawasaki disease

[first paragraph of article] Kawasaki disease (KD) continues to interest, intrigue, and challenge clinicians, basic scientists, and engineers. One of the defining features of the disease is the development of coronary aneurysms of varying sizes and shapes, reproducing the phenomenon of ‘‘River into a lake’’, and introducing profound changes in the coronary circulation. These changes reflect many physical, engineering and even cultural beliefs which might be of interest to the readers of this special issue of the Journal dealing with KD. Some of these ideas are presented in this article.
