Key result
Coronary angiography in a 29-year-old woman with postpartum myocardial infarction resulted in iatrogenic dissection, suggesting initial infarctions with normal angiograms may be due to healed dissections.
Case Report (n=1)
This case suggests that myocardial infarctions in patients with angiographically normal coronary arteries may be caused by healed dissections, and highlights the risk of iatrogenic dissection during angiography.
Suggests caution with angiography in postpartum MI; hypothesis-generating for healed dissections as MINOCA cause.
A 29 year old woman had a myocardial infarction three weeks post partum. Coronary angiography was performed six days later. No abnormalities were seen initially, but re-injection of the left coronary artery resulted in a dissection that extended through the anterior descending and circumflex branches and a reinfarction. This case suggests that myocardial infarctions occurring in patients with angiographically normal coronary arteries may be caused by dissections that heal by the time of catheterisation.

Movsesian et al. (1989) conducted a case report in Postpartum myocardial infarction (n=1). Coronary angiography was evaluated. Coronary angiography in a 29-year-old woman with postpartum myocardial infarction resulted in iatrogenic dissection, suggesting initial infarctions with normal angiograms may be due to healed dissections.
