Anomalous Left Coronary Artery from the Pulmonary Artery

🔹️Pediatric Echocardiography Review🔹️ ✅ALCAPA Anomalous left coronary artery from the pulmonary artery (ALCAPA), also known as Bland-White-Garland syndrome (BWG), is a rare congenital coronary artery anomaly and is considered one of the most severe of such anomalies. ALCAPA is a problem that occurs when the baby’s heart is developing early in the pregnancy. The developing blood vessel to the heart muscle does not attach correctly. In the normal heart, the LCA originates from the aorta. It supplies oxygen-rich blood to the heart muscle on the left side of the heart as well as the mitral valve (the heart valve between the upper and lower chambers of the heart on the left side). The aorta is the major blood vessel that takes oxygen-rich blood from the heart to the rest of the body. In children with ALCAPA, the LCA originates from the pulmonary artery. The pulmonary artery is the major blood vessel that takes oxygen-poor blood from the heart to the lungs to pick up oxygen. When this defect occurs, blood that is lacking in oxygen is carried to the heart muscle on the left side of the heart. Therefore, the heart muscle does not get enough oxygen. The tissue begins to die due to lack of oxygen. This can cause a heart attack in the baby. A condition known as "coronary steal" further damages the heart in babies with ALCAPA. The low blood pressure in the pulmonary artery causes blood from the abnormally connected LCA to flow back toward the pulmonary artery instead of toward the heart muscle. This results in less blood and oxygen to the heart muscle. This problem can also lead to a heart attack in a baby. Coronary steal develops over time in babies with ALCAPA if the condition is not treated early. #pediatric #pediatricechocardiography #Echocardiography #congenitaldefects
