Key result
Rotational atherectomy during primary PCI for STEMI achieved final TIMI 3 flow in 19 of 21 patients, with 20 patients surviving to hospital discharge and no marked increase in no-reflow.

Rotational atherectomy during primary PCI for STEMI can be performed safely and effectively in complex, heavily calcified lesions when conventional techniques are inadequate.
No takes yet. Share an insight, caveat, or question.
Feasible in select STEMI cases; leaves open efficacy versus standard PCI pending randomized trials.
Mahmood et al. (2017) conducted an observational in ST-elevation myocardial infarction (STEMI) with heavily calcified coronary arteries (n=21). Rotational atherectomy was evaluated on Clinical and procedural characteristics, and in hospital outcomes. Rotational atherectomy during primary PCI for STEMI achieved final TIMI 3 flow in 19 of 21 patients, with 20 patients surviving to hospital discharge and no marked increase in no-reflow.
