Figure 1: Cardiac catheterization of the left coronary system (A) and right coronary system (B) demonstrating complete occlusion of the proximal portion of the right coronary artery (RCA). Cardiac catheterization establishing the presence of left to right collateral branches (C and D, indicated by arrows) with filling of the distal RCA (E, indicated by arrows). Previously inserted drug eluting stent can be seen in the distal RCA (F, indicated by oval).

Figure 2: Cardiac catheterization (A and B) and transthoracic echocardiogram (C and D) demonstrating severe global hypokinesis of the left ventricle with a significantly reduced ejection fraction of 10% by comparison of systole (A and C) and diastole (B and D).
