Cardiac Sonographers 👋 Atrial septal defect? What should we look for on echocardiography? An ASD is a defect in the atrial septum that allows blood to shunt—most commonly from the left atrium (higher pressure) to the right atrium (lower pressure). But spotting the hole is only the beginning 👀 Key echo clues to evaluate: • Right heart enlargement • Signs of pulmonary hypertension • Shunt direction & flow patterns • Qp:Qs for shunt severity We send short, focused echo lessons every Tuesday & Thu
