Clinical introduction
A young patient complaining of chest tightness was admitted to our hospital. The ECG showed T-wave inversion at leads Ⅱ, Ⅲ and aVF (aVF is an augmented unipolar limb lead, “a” is augmented, “V” is voltage and “F” is left foot), and heart auscultation was normal. The coronary and thoracic aortic CT angiography indicated coronary artery stenosis and a filling defect (figure 1A, arrows) in the ascending aorta (AAO). Subsequently, transoesophageal echocardiography was performed, which showed a movable mass (figure 1B–D and online supplemental figure 1, arrows) with a size of 27 mm×7 mm attached to the anterior wall of the AAO. The local blood flow was unobstructed (online supplemental video 1).
