Insights
A rare calcified thrombus in the coronary artery was identified using advanced imaging. Successful stenting confirmed the diagnosis, distinguishing it from a calcified nodule.
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
Background:
- Calcified thrombi are uncommon intracoronary masses.
- Distinguishing calcified thrombi from calcified nodules is clinically important.
Observation:
- A case of acute coronary syndrome presented with a large, mobile intracoronary mass.
- Optical frequency domain imaging and intravascular ultrasound were utilized for characterization.
Findings:
- The intracoronary mobile mass was definitively identified as a calcified thrombus.
- Successful direct stenting provided functional confirmation of the thrombus diagnosis.
Implications:
- Cardiologists must consider calcified thrombus in the differential diagnosis of intracoronary mobile masses.
- Combined use of optical frequency domain imaging and intravascular ultrasound aids accurate diagnosis.
Objectives:
A calcified thrombus is rare, but needs to be recognized and to be differentiated from calcified nodule.
Methods:
We report a case of acute coronary syndrome and a large intracoronary mobile mass, which was identified as a calcified thrombus by optical frequency domain imaging and intravascular ultrasound.
Results:
Successful direct stenting indicated that mobile mass was a calcified thrombus, not a calcified nodule.
Conclusions:
Cardiologists should be aware that an intracoronary mobile mass could be a calcified thrombus. This diagnosis can be confirmed through the combined use of optical frequency domain imaging and intravascular ultrasound.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
