Conclusion
ST is a medical emergency that may be associated with death, myocardial
infarction, and significant cardiac morbidity, which mainly requires
revascularization.
This case emphasized IVUS as a highly useful modality for investigating
the causal mechanisms of ST, as it reveals pathophysiologic factors
underestimated by conventional angiography and identifies patients who
may benefit from more additional coronary interventions, and it should
be at the center of our attention.
