Spontaneous Coronary Artery Dissection Causing Cardiac Arrest in a Post-Partum Patient – A Case Report

Spontaneous coronary artery dissection is a rare condition that can precipitate acute coronary syndrome in pregnant and peripartum women. A 32-year-old previously healthy female, 2-weeks post-partum, presented to the emergency department after sudden cardiac arrest. Return of spontaneous circulation was achieved after multiple rounds of resuscitation. Electrocardiogram revealed ST elevations in the anterolateral leads with reciprocal changes. She was taken to the catheterization lab by cardiology and was found to have a dissection of the distal left anterior descending coronary artery. The patient was subsequently treated medically with heparin and antiplatelet therapy, but ultimately died of anoxic encephalopathy. The purpose of this report is to describe the risk factors, presentation, and management of spontaneous coronary artery dissection which can be easily overlooked given its rarity. TOPICS: Spontaneous coronary artery dissection, out-of-hospital cardiac arrest, peri-partum complications.
