Electrocardiogram showed sinus tachycardia, Q wave was observed in V2-4 (Fig. 1a). Transthoracic echocardiogram (TTE) and 3-dimensional TTE revealed giant dilatation of left anterior descending coronary artery (LAD; 16 mm) with massive intraluminal thrombus (Fig. 1b, Fig. 1 Video 1, 2), dilated right coronary artery (RCA; 6 mm), enlarged left ventricle with abnormal wall motion (left ventricular ejection fraction: 48%) (Fig. 1c, Fig. 1 Video 3). Coronary computed tomography angiography confirmed giant dilatated and distal-blocked LAD (17 mm) (Fig. 1d, Fig. 1e).

Positron emission tomography also revealed large myocardial perfusion defect in left ventricular apical segment and survival of some mid anterior myocardial cells (Fig 2. arrows).
