A chest x-ray revealed mild pulmonary congestion and an electrocardiogram confirmed sinus tachycardia (Figure 1).
Initial transthoracic echocardiography shows severe global hypokinesis with apical immobile thrombus (arrow) in (A) apical 4-chamber and (B) apical 2-chamber views. Coronary angiogram shows normal epicardial arteries from (C) left anterior oblique and (D) right anterior oblique views. LM: left main coronary artery; LAD: left anterior descending artery; LCx: left circumflex artery; RCA: right coronary artery.

A TTE demonstrated severe global left ventricular dysfunction with a left ventricular ejection fraction (LVEF) of 20% and an immobile apical mural thrombus (Figure 2A and 2B; Videos 1 and 2). A coronary angiogram showed normal epicardial coronaries (Figure 2C and 2D).

He achieved full recovery, and TTE 1 month later revealed LVEF recovery to 60% without evidence of apical thrombus (Figure 3A and 3B; Videos 3 and 4).
