This book covers the latest information on the anatomic features, underlying physiologic mechanisms, and treatments for diseases of the heart. Key chapters address animal models for cardiac research, cardiac mapping systems, heart-valve disease and genomics-based tools and technology.
The heart is located behind the sternum; however, it normally lies “down” with the apex pointing toward the left side. This chapter provides a succinct overview of the gross anatomy of the heart and its blood vessels as well as some clinical aspects pertinent to its structure.
20 kwi 2023 · In the anatomical position, the heart has five surfaces – each formed by the different chambers of the heart: Anterior (or sternocostal) – Right ventricle. Posterior (base of the pyramid) – Left atrium.
3 sie 2023 · The surface projections of the heart represent points on the thoracic wall that map out the outline and valves of the heart. These include four borders (superior, right, inferior, left) and four valves (left atrioventricular, right atrioventricular, aortic, pulmonary). The main reference points used for the surface projections of the heart are ...
1 cze 2022 · The right border of the heart is shown by the red dotted line, the left border, or obtuse border of the ventricular mass, by the yellow dotted line, and the diaphragmatic border, or acute border of the ventricular mass, by the green dashed line.
The heart is placed in the mediastinum, between the lungs, and is encased by the pericardial sac, which has a posterior border near the spinal column and an anterior border near the sternum, with the diaphragmatic crurae on the inferior surface [1].
3 lis 2023 · Key facts about the heart. Borders. Superior (atria, auricles), inferior (right and left ventricles), left (left auricle, left ventricle), right (right atrium) borders. Surfaces. Sternocostal (right ventricle), diaphragmatic (mostly right ventricle, portion of left ventricle), pulmonary (cardiac impression) surfaces.
