Figure 3 Coronary angiography findings(A–D) Selective coronary angiograms demonstrating no significant stenosis of the left anterior descending (A), left circumflex (B), or right coronary artery (C). An incidental small fistula from the right coronary artery to the right ventricle is noted (C, arrow). Left ventriculography (D) demonstrates normal chamber size and contractility, excluding obstructive coronary artery disease and supporting the diagnosis of myocardial infarction with non-obstructive coronary arteries (MINOCA).
