Abstract

In-stent atheromatous plaque rupture is a very rare event. A 51-year-old man presented with an acute inferior myocardial infarction 9 years after bare-metal stent implantation in the mid-portion of right coronary artery. After thrombolytic therapy, coronary angiography and intravascular ultrasound (IVUS) revealed a ruptured plaque at the mid portion of the stented segment.

Figure

• 

  Fig. 1 Angiogram of the right coronary artery. A, B: the initial coronary angiogram revealed a wedged shape intraluminal filling defect in the stent area. C, D: successful reperfusion was achieved after stenting.

  Fig. 2 Cross-sectional intravascular ultrasound images of the RCA. A: the initial IVUS images showed ruptured plaque (white arrow). B: the post IVUS examination revealed adequate expansion and apposition without complication.
