Left atrial enlargement (LAE) or left atrial dilation refers to enlargement of the left atrium (LA) of the heart, and is a form of cardiomegaly. In both mitral stenosis and mitral regurgitation, it’s more difficult for the left atrium to pump blood into the left ventricle. Severely enlarged left atrium. As in adults, the coexistence of ECG diagnostic criteria for both the left and right atrial enlargement suggest biatrial enlargement (Figure 29-3).
