Hypothesis
Can optical coherence tomography (OCT) effectively identify the mechanisms of stent thrombosis?
Conclusion
The study demonstrates that OCT can reveal stent underexpansion as a key factor in early stent thrombosis.
Supporting Evidence
- OCT revealed severe focal stent underexpansion localized in the overlap segment.
- The patient presented an acute myocardial infarction with ST segment elevation six days after PCI.
- Angiography showed in-stent thrombosis of the proximal LCX.
Takeaway
A patient had a heart attack because a stent in his artery didn't expand properly, and a special camera helped doctors see the problem.
Methodology
The case involved the use of optical coherence tomography to evaluate stent underexpansion in a patient with stent thrombosis.
Participant Demographics
53-year-old male with a history of arterial hypertension and ex-smoker.
