At that time, she underwent successful percutaneous intervention with two drug-eluting stents to the distal right coronary artery (Figure 2).

ST-elevations consistent with acute ST-elevation myocardial infarction. She underwent left heart catheterization remarkable for 90% stenosis of the first obtuse marginal branch (Figure 3), which was revascularized with a third drug-eluting stent (Figure 4).

Diagnostic catheterization also revealed new 40-50% restenosis of her previous distal RCA stent (Figure 5) and noncritical stenosis of the first diagonal branch (Figure 6).
