Most are ordered for respiratory symptoms, routine health examinations, or emergency evaluations. Yet among these seemingly ordinary studies lie subtle cardiac findings that may dramatically influence a patient's prognosis. One of the most underrecognized—but clinically significant—examples is left atrial enlargement (LAE) . Although echocardiography remains the gold standard for evaluating valvular heart disease, experienced radiologists often identify the earliest clues long before an ultrasound is performed.

However, contrast-enhanced CT ...
