Spontaneous Coronary Artery Dissection in a Patient With Cardiogenic Shock: To Revascularize or Not to Revascularize?

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS), predominantly affecting young individuals.
• While supportive care is standard for uncomplicated SCAD, its role in severe cases, particularly with cardiogenic shock, remains uncertain.
• Revascularization strategies like percutaneous coronary intervention (PCI) and coronary artery bypass graft surgery (CABG) carry significant perioperative risks in SCAD patients.

Observation:

• A 40-year-old female with no prior medical history presented with SCAD complicated by Society for Cardiovascular Angiography & Interventions (SCAI) stage D cardiogenic shock.
• The patient was successfully managed with a percutaneous left ventricular assist device (LVAD) as a supportive measure.
• No revascularization procedures (PCI or CABG) were performed during the acute phase.

Findings:

• Repeat coronary angiography demonstrated spontaneous healing of the left anterior descending (LAD) artery dissection.
• Significant recovery of left ventricular (LV) systolic function was observed post-treatment.
• The patient's cardiogenic shock resolved with LVAD support and conservative management.

Implications:

• This case underscores the efficacy of intensive supportive care, including mechanical circulatory support, for SCAD patients experiencing cardiogenic shock.
• It suggests that avoiding revascularization may be a safer approach in select SCAD cases due to high perioperative risks.
• Further research is warranted to establish optimal management guidelines for complex SCAD presentations, balancing risks and benefits of interventions versus conservative strategies.
