This heart anatomy book describes the cardiac development and cardiac anatomy in the development of the adult heart, and is illustrated by numerous images and examples. It contains 550 images of dissected embryo and adult hearts, obtained through the dissection and photography of 235 hearts. It has been designed to allow the rapid understanding of the key concepts and that everything should be clearly and graphically explained in one book. This is an atlas of cardiac development and anatomy of the human heart which distinguishes itself with the use of 550 images of embryonic, fetal and adult hearts and using text that is logical and concise. All the mentioned anatomical structures are shown with the use of suggestive dissection images to emphasize the details and the overall location. All the images have detailed comments, while clinical implications are suggested. The dissections of different hearts exemplify the variability of the cardiac structures. The electron and optical microscopy images are sharp and provide great fidelity. The arterial molds obtained using methyl methacrylate are illustrative and the pictures use suggestive angles. The dissections were made on human normal and pathological hearts of different ages, increasing the clinical utility of the material contained within.
