Key result
Rotational atherectomy during primary PCI for STEMI achieved an 86.5% procedural success rate, with in-hospital mortality of 50% in patients with cardiogenic shock versus 1.5% without (P<0.0001).
Why the study?
Rotational atherectomy is off-label in STEMI but can be the only option in severely calcified culprit lesions, leading investigators to assess its safety and feasibility during PPCI.
Is rotational atherectomy safe and feasible during primary percutaneous coronary intervention in patients with STEMI?
Observational (n=104)
Yes
Is rotational atherectomy safe and feasible during primary percutaneous coronary intervention in patients with STEMI?
Rotational atherectomy is a feasible bailout strategy with high procedural success during primary PCI for STEMI, and is associated with low in-hospital mortality in patients without cardiogenic shock.
No takes yet. Share an insight, caveat, or question.
RA during PPCI may be feasible in selected calcified STEMI lesions; leaves open safety questions pending randomized trials.
Hemetsberger et al. (2023) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=104). Rotational atherectomy was evaluated on Procedural success (successful stent implantation with final TIMI flow 3 and residual stenosis < 30%). Rotational atherectomy during primary PCI for STEMI achieved an 86.5% procedural success rate, with in-hospital mortality of 50% in patients with cardiogenic shock versus 1.5% without (P<0.0001).
