This diagram provides a clear visual explanation of the Arterial Switch Operation (ASO), a complex but life-saving surgical procedure used to correct transposition of the great arteries (TGA). The top panel illustrates the heart's anatomy before the operation, highlighting the abnormal connections of the great arteries. The bottom panel demonstrates the corrected anatomy post-surgery, showcasing how the arteries are reconnected to ensure proper blood flow. This detailed visual guide is crucial for understanding how this intricate surgery restores normal cardiovascular circulation in affected infants.

This diagram illustrates the critical technique for adult cardiopulmonary resuscitation (CPR), specifically focusing on the correct hand placement for chest compressions. CPR is a life-saving emergency procedure performed when the heart stops beating, aiming to maintain blood flow to the brain and other vital organs until professional medical help arrives. Understanding the anatomical landmarks and the mechanics of effective chest compressions, as depicted here, is paramount for anyone learning this essential skill. This guide will delve into the proper methodology to maximize the chances of a positive outcome during a cardiac arrest event.

This diagram provides a comprehensive overview of aortic coarctation and its repair using various advanced imaging techniques. Aortic coarctation is a congenital narrowing of the aorta, often located near the ductus arteriosus, which significantly impedes blood flow to the lower body. The diverse images—A: 'Black-blood' oblique sagittal view, B: 3D contrast-enhanced CT angiogram, C: 3D contrast-enhanced MR angiogram, and D: another 3D contrast-enhanced MR angiogram—collectively demonstrate the condition's characteristics and potential post-surgical complications. Understanding these visual details is crucial for accurate diagnosis, treatment planning, and long-term management of this complex cardiovascular anomaly.

This chest X-ray (CXR) diagram illustrates dilated cardiomyopathy, a serious condition affecting the heart's ability to pump blood effectively. The image provides a clear visual representation of cardiac enlargement, which is a hallmark feature of this disease. By examining such radiological findings, medical professionals can gain crucial insights into the extent of heart remodeling and guide appropriate diagnostic and therapeutic strategies for patients suffering from this condition.
