Key result
PCI and MCS temporarily restore flow in postpartum LM SCAD before fatal progressive heart failure.
Why the study?
Postpartum spontaneous coronary artery dissection is a rare cause of vessel occlusion and heart attack, warranting report to enhance clinicians' understanding and inform treatment approaches.
Case Report (n=1)
No
Postpartum spontaneous coronary artery dissection involving the left main coronary artery is a rare, highly lethal condition that can rapidly progress to refractory cardiogenic shock despite urgent revascularization and mechanical circulatory support.
Anticipate refractory HF despite PCI and MCS; leaves open novel therapies for postpartum left main SCAD.
Introduction: Postpartum spontaneous coronary artery dissection (PSCAD) is a non-iatrogenic coronary artery wall separation typically occurring within weeks of childbirth and resulting in vessel occlusion and heart attack. This report presents a case of PSCAD involving the left main (LM) coronary artery. Case Presentation: A 27-year-old woman was admitted to emergency care due to sudden chest pain lasting for 1.5 hours. Coronary angiography suggested complete occlusion of the LM coronary artery, and she was urgently transferred to a provincial-level hospital. A 3.0 × 22-mm Endeavor Resolute stent was implanted in the proximal LM and left anterior descending coronary arteries. Postoperatively, mechanical circulatory support was provided using veno-arterial extracorporeal membrane oxygenation (VA-ECMO), an intra-aortic balloon pump (IABP), intermittent continuous renal replacement therapy, and non-invasive ventilation. The clinical symptoms of the patient improved temporarily. However, after withdrawal of the IABP and VA-ECMO, the patient’s symptoms worsened, and she died while awaiting heart transplantation. Conclusion: We report a rare case of PSCAD involving the LM coronary artery with the aim of enhancing clinicians’ understanding of PSCAD and providing insights for treatment approaches.

Jing et al. (2026) conducted a case report in Postpartum young woman (age 27) with postpartum spontaneous coronary artery dissection involving the left main coronary artery complicated by cardiogenic shock (n=1). Percutaneous coronary intervention (PCI) with 3.0 × 22-mm Endeavor Resolute stent implanted in the left main and proximal left anterior descending arteries was evaluated on Restoration of coronary artery flow with TIMI grade 3 and survival status after PCI and mechanical support. PCI with stent implantation and mechanical circulatory support temporarily improved coronary flow and symptoms in postpartum spontaneous coronary artery dissection involving the left main artery, but the patient died from progressive heart failure within weeks.
