The heart’s internal anatomy is a complex network that drives its life-sustaining function, revealed vividly in this anterior view. This diagram showcases the four chambers, major vessels with their early branches, and the critical valves, with the pulmonary trunk and aorta partially obscuring the interatrial septum and the atrioventricular septum cut away for clarity. Exploring this image provides a deeper appreciation of how the heart coordinates blood flow through its intricate internal structures.

The heart’s ventricles exhibit remarkable differences in muscle thickness, reflecting their distinct roles in circulation. This diagram illustrates the left ventricle and right ventricle in both relaxed and contracting states, highlighting how the thicker myocardium of the left ventricle generates greater pressure for systemic circulation. Exploring this image provides a clear understanding of how ventricular anatomy supports the body’s dual circulatory demands.

The heart’s ability to pump blood relentlessly relies on its intricate musculature, a marvel of biological engineering. This diagram illustrates the swirling patterns of cardiac muscle tissue, highlighting the atrial musculature and ventricular musculature that drive circulation. Delving into this image reveals the anatomical foundation that supports the heart’s rhythmic contractions and sustains life.

The heart is enveloped by a protective pericardial membrane, a critical structure that supports its function and movement within the chest. This diagram illustrates the three layers of the pericardium and the pericardial cavity, alongside the three layers of the heart wall, with a shared epicardium linking these structures. Delving into this image provides a deeper understanding of the heart’s anatomy and the protective mechanisms that ensure its efficient operation.

The Norwood procedure is a critical surgical intervention for infants born with hypoplastic left heart syndrome (HLHS), a severe congenital heart defect. This article provides an in-depth look at the Norwood surgical correction, as illustrated in the medical image, offering a detailed anatomical and procedural breakdown. Designed for medical students and professionals, this guide explores the surgical technique, its significance in treating HLHS, and the anatomical structures involved, ensuring a thorough understanding of this life-saving operation.
