An atrial thrombus is a blood clot that forms within the atria, the upper chambers of the heart. These clots often arise in conditions like atrial fibrillation, where irregular heartbeats lead to stagnant blood flow, increasing the risk of clot formation. Detecting atrial thrombi is crucial in cardiac ultrasound (echocardiography) as they pose a significant embolic risk, potentially causing strokes or other systemic embolisms.
Ultrasound imaging provides non-invasive visualization of the heart’s chambers, allowing cardiologists and sonographers to identify, characterize, and monitor atrial thrombi. Early detection via cardiac ultrasound is vital for guiding therapeutic interventions, such as anticoagulation, to prevent life-threatening complications. Understanding atrial thrombus formation and its appearance on ultrasound is essential for accurate medical diagnosis and patient management.
