Figure 1.
(A) Angiogram in left anterior oblique (LAO) view demonstrating ulcerative plaque in the mid right coronary artery with 70% stenosis (black arrow) and distal embolism (black asterisk). (B) Angiogram in LAO view demonstrating a de novo lesion with features suggestive of intramural hematoma (white asterisk).

Figure 2.
(A) Angiogram in left anterior oblique view demonstrates haziness within a 70% stenosis proximal to stent edge (white arrow). This was the region of previous suspected hematoma; however, stenosis progressed. (B) Intravascular ultrasound reveals an intramural hematoma (white asterisk) proximal to the stent.

Figure 3.
(A) Angiogram in left anterior oblique view following proximal stent deployment shows a de novo stenosis of 50% to 60% (black asterisk). (B) Intravascular ultrasound of proximal right coronary artery lesion confirms the intramural hematoma (white asterisk).

Figure 4.
(A) Angiogram in left anterior oblique (LAO) view confirming the presence of acute in-stent thrombosis (black asterisk) within the proximal right coronary artery. (B) Angiogram in LAO view showing resolution of thrombus (white asterisk) and proximal prestented hematoma (black arrow) following angioplasty and completion of the “chimney sweep technique.”
