Insights
A flow artifact can mimic coronary thrombus, complicating interventions. This case highlights "pseudothrombus" in severe left circumflex stenosis, emphasizing accurate diagnosis for better patient outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Imaging
Background:
- Coronary interventions become more complex, costly, and morbid with the presence of coronary thrombus.
- Accurate identification of angiographic filling defects is crucial for guiding treatment strategies.
- Distinguishing true thrombus from artifacts is essential for appropriate patient management.
Observation:
- A case report details a flow artifact mistaken for thrombus.
- This artifact, termed "pseudothrombus," occurred in a patient with severe proximal stenosis.
- The affected artery was the left circumflex coronary artery.
Findings:
- The study identified a specific flow artifact that can visually replicate coronary thrombus on angiography.
- This pseudothrombus was associated with significant proximal stenosis in the left circumflex artery.
- The findings underscore the importance of recognizing imaging artifacts in interventional cardiology.
Implications:
- Accurate differentiation between pseudothrombus and actual thrombus can prevent unnecessary or incorrect interventions.
- Recognizing this artifact may lead to improved procedural planning and reduced complication rates.
- This case contributes to the understanding of diagnostic challenges in coronary angiography.
Abstract:
Since the complexity, morbidity, and costs of coronary interventions are increased when coronary thrombus is present, identification of the cause of an angiographic filling defect is potentially important. We present a case report and review our experience with a flow artifact that mimicked thrombus ("pseudothrombus") in the setting of a severe proximal stenosis in the left circumflex coronary artery.
