Question
What are the results of the four-month-old’s heart ultrasound?
Answer
At four months old, the heart ultrasound revealed that the heart’s position and structure are normal, but there is a slight enlargement of the left atrium and left ventricle chambers. The flow velocity in the left ventricular outflow tract is 1.2 meters per second, with no widening of the aorta. The wall of the right ventricular outflow tract is slightly thickened, which has no impact on blood flow, with a flow velocity of 1.6 meters per second. The pulmonary artery is slightly widened, with valves opening actively. The atrioventricular valves open actively. The foramen ovale has not closed, with a fine thread-like left-to-right shunt. There is a ventricular septal defect (membranous peripheral fusion type, extending from inflow to outflow tract) of 0.53 millimeters. The right coronary cusp of the aorta is slightly protruding into the ventricular septal defect, with a left-to-right shunt velocity of 4.682 meters per second. The aortic arch is in the left position. There is a small amount of pericardial effusion in the heart.
