Bottom Line: Based on the results of the OCT, the patient underwent an elective coronary angioplasty with standard anticoagulation.The use of OCT permitted a correct diagnosis and a successful treatment.This paper provides a discussion of the advantages and disadvantages of OCT, and a comparison with intravascular ultrasound.

ABSTRACT
Although its use in daily practice is not common, optical coherence tomography (OCT) is a powerful research tool in invasive cardiology. This report describes a hazy angiography image after percutaneous coronary intervention that has been assessed using OCT. Based on the results of the OCT, the patient underwent an elective coronary angioplasty with standard anticoagulation. After implantation of the stent, an intracoronary hazy image was seen on angiography. The use of OCT permitted a correct diagnosis and a successful treatment. This paper provides a discussion of the advantages and disadvantages of OCT, and a comparison with intravascular ultrasound.

Optical coherence tomography imaging of left anterior descending artery. Distal (A): correct apposition of the stent without intraluminal content. Middle (B): a signal rich, low-backscattering protrusion image compatible with white thrombus (mark), which occupies the greater part of the vessel lumen. Proximal (C): stent malapposition (arrow head) in the proximal border, with small images of thrombus.

Figure 3: Optical coherence tomography imaging of left anterior descending artery. Distal (A): correct apposition of the stent without intraluminal content. Middle (B): a signal rich, low-backscattering protrusion image compatible with white thrombus (mark), which occupies the greater part of the vessel lumen. Proximal (C): stent malapposition (arrow head) in the proximal border, with small images of thrombus.

Mentions: The stent was fully expanded but showed some strut malapposition at the proximal border (Fig. 3). We performed manual thrombus aspiration and obtained white thrombus material. We postdilated the proximal segment of the stent with a non-compliant balloon. The final result was significant reduction of the thrombus and correction of the stent malapposition (Fig. 4).
