Enhancing the clarity of the heart’s inner lining with ultrasound contrast improves thrombus detection in the left ventricle and left atrium. Using 2D or 3D transthoracic echocardiography with contrast makes the blood pool look brighter and the endocardial borders crisper, so any non-enhancing area stands out more clearly as a potential thrombus. This contrast-opacified view helps reveal small or difficult-to-see thrombi, such as those in the LV apex or within the left atrial appendage, by providing a stark contrast between the bright cavity and a nonperfused, echo-free mass.

While MRI can detect thrombus and transesophageal echocardiography is highly sensitive for left atrial thrombus, contrast-enhanced transthoracic echocardiography offers a rapid, widely available, noninvasive way to boost sensitivity in routine assessment. Color Doppler by itself adds flow information but does not reliably distinguish thrombus from artifact without the enhanced endocardial delineation that contrast provides.
