Role of intravascular ultrasound in the diagnosis of spontaneous coronary artery dissection

Abstract

The diagnosis of spontaneous coronary artery dissection as a cause of acute coronary syndrome has increased since the arise of intravascular imaging techniques. However, it still remains an underdiagnosed entity. Evidence related to its management is scarce, but conservative strategies have shown favorable outcomes in selected patients. We present the case of a 55-year-old female patient who is diagnosed with a non-ST segment elevation myocardial infarction. Spontaneous coronary artery dissection is suspected in the coronary angiography and then confirmed by intravascular ultrasound. Conservative management was selected, with favorable clinical outcomes.
