The role of cardiac computed tomography in diagnostic and prognostic assessment of pregnancy related spontaneous coronary artery dissection: a case report

Abstract

Spontaneous coronary artery dissection (SCAD) is the most common cause of myocardial infarction during pregnancy or the postpartum period and has a major impact on cardiovascular morbidity and death in pregnant women. A 38-year-old woman with sudden cardiac arrest ten days postpartum urgently underwent coronarography, which showed an intraparietal hematoma of the left anterior descending (LAD) artery. Two days later, coronary computed tomography angiography (CCTA) was performed, which showed the evidence of SCAD in the mid-distal tract of LAD and the presence of transmural ischemic infarction in the apex and mid antero-septal wall in delayed acquisition. The patient was treated with a beta-blocker. Four months later CCTA showed complete resolution of SCAD and evolution of the infarcted areas. Given the high accuracy and noninvasiveness of CCTA, our case highlights the potential role of this imaging modality in the diagnosis and follow-up of pregnancy associated SCAD.
