However, the proximal obtuse marginal branch of the left circumflex (LCX) artery was noted to have a complete occlusion (Figure 1). 
After a successful percutaneous coronary intervention, the occluded segment of the proximal portion of the obtuse marginal artery was fully reperfused (white arrow).

After placement of two bare-metal stents, TIMI grade 3 (normal) flow with limited myocardial blush was observed (Figure 2).
Two-dimensional echocardiogram demonstrates an irregular mass in the left atrium during the end-systolic phase of the cardiac cycle (white arrow).

A transthoracic 2D echocardiogram performed two days after the intervention revealed a very large irregular mobile mass attached to the superior atrial septum freely prolapsing to the left ventricle (Figures 3 and 4).
Two-dimensional echocardiogram demonstrates the irregular mass prolapsing to the left ventricle during the middiastolic phase of the cardiac cycle (white arrow).
