How does a normal septal motion appear on echocardiography?

A normal septal motion on echocardiography is characterized by synchronized movement during both systole and diastole. This means that the interventricular septum, which is the wall separating the left and right ventricles, contracts and relaxes in coordination with the overall movement of the heart chambers. During systole, the septum moves towards the left ventricle, helping to facilitate effective pumping of blood out of this chamber. In diastole, the septum returns to its original position as the ventricles fill with blood, maintaining the overall rhythmic mechanics of the heart.

This coordinated motion is essential for optimal cardiac function and reflects healthy left and right ventricular interactions. If the septum were to display asynchronous movement, remain static, or bulge abnormally, this could indicate underlying cardiac dysfunction or pathology, such as ventricular septal defects or other forms of cardiac anomalies. The normal synchronized motion signifies that the heart's chambers are working harmoniously, which is crucial for efficient circulation.
