Overview

Spontaneous Coronary Artery Dissection (SCAD)

Stable,no high-risk feature

High-risk feature present

Left main dissection

Ongoing/recurrent ischemia

Ventricular tachycardia or fibrillation

Cardiogenic shock

Hemodynamically unstable?

No

Yes

Consider: Intra-aortic balloon pump, Extra corporeal membrane oxygenation, Left ventricular assist device, Implantable cardioverter defibrillator

Isolated Left Main

Involving Left Anterior Descending (LAD +/or circumflex

Is percutaneous coronary intervention (PCI) feasible?

No

Yes

Ostial LAD or ≥ 2 proximal SCAD?

Conservative therapy

PCI

Coronary artery bypassing

Conservative therapy

PCI

Adjunctive medical therapy
Aspirin and beta-blocker (± clopidogrel, ACEI/ARB, statin)

Monitor in-hospital for 3 to 5 days
