Spontaneous left main dissection treated by percutaneous coronary intervention

Area of Science:

• Cardiology
• Vascular Medicine
• Diagnostic Imaging

Background:

• Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndromes and sudden cardiac death.
• SCAD presents with variable clinical symptoms, making prompt diagnosis challenging.
• Effective management of SCAD involves medical therapy, percutaneous coronary intervention, or surgical revascularization.

Observation:

• A young woman presented with symptoms initially diagnosed as coronary thrombus.
• The underlying cause was identified as spontaneous coronary artery dissection of the left main coronary artery.
• The patient successfully underwent percutaneous coronary stenting for the condition.

Findings:

• Distinguishing SCAD from coronary thrombus can be difficult, even with advanced diagnostic tools.
• Successful percutaneous coronary stenting is a viable treatment option for SCAD involving the left main artery.
• This case represents the fourth reported instance of left main stenting in SCAD patients.

Implications:

• SCAD should be considered in the differential diagnosis of chest pain, particularly in young women.
• Early and accurate diagnosis of SCAD is crucial for improving patient prognosis.
• Further research is needed to refine diagnostic and therapeutic strategies for SCAD.
