Based on real observations, collected by accredited university lecturers, Redha Lakehal and Jalaleddinne Omar Bouhidel offer us, on about forty pages, an anthology of five clinical cases of cardiac surgery with tumor patients as a background theme.Richly illustrated, this very didactic book is intended for a wide range of readers, both experienced cardiologists and those in training, who will realize the originality of a situation that is very rarely encountered in a surgical context, a rarity that one would not have imagined for a family.The authors, seasoned university lecturers, have, among other things, the great merit of making accessible, in simple terms, a surgical discipline that is easily perceived as complicated. They are warmly thanked and congratulated.Constantine, December 23, 2022
