ROSC and culprit lesion yield by arrest rhythm

April 5, 2026Haney Mallemat

Haney Mallemat argues cath lab activation decisions after ROSC should move beyond rhythm-based reflexes, noting high culprit yield in STEMI but meaningful yield even in VFib VT and PEA asystole.

ROSC & Culprit Lesions
STEMI: 98% culprit lesion yield
VFib/VT: ~35% yield • PEA/Asystole: Still have culprits!
