Accuracy of Angiographic Identification of Culprit Lesions in Women With Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA)

Circ Cardiovasc IntervPublished

  • diagnostic accuracy study
  • blinded independent review by two interventional cardiologists
  • core laboratory confirmation with angiographic coregistration

Authors' conclusion

Interventional cardiologists could not reliably identify culprit arteries using coronary angiography in women with MINOCA, even after ECG and transthoracic echocardiography review. Our findings suggest that invasive angiography alone should not guide vessel selection for intracoronary imaging and support multivessel imaging when evaluating MINOCA.

Study context

Population
Women with MINOCA who had a coronary culprit lesion identified by multivessel optical coherence tomography (OCT)women with MINOCA
Participants
64 women
Comparison
Interventional cardiologists' identification of the culprit artery on invasive coronary angiography, before and after review of ECG and transthoracic echocardiography, against OCT-defined culprit lesions
