Key result
Rotatripsy enables stent delivery in undilatable coronary lesions by modifying heavily calcified plaque.
Why the study?
In balloon-uncrossable calcified coronary lesions, additional strategies beyond rotational atherectomy are needed when lesions remain undilatable to enable stent delivery.
Does rotatripsy improve stent delivery in heavily calcified coronary lesions that are undilatable after rotational atherectomy?
Does rotatripsy improve stent delivery in heavily calcified coronary lesions that are undilatable after rotational atherectomy?
Rotatripsy is a hybrid approach combining rotational atherectomy and intracoronary lithotripsy that can facilitate stent delivery in heavily calcified, undilatable coronary lesions.

May aid stent delivery in refractory calcified lesions; hypothesis-generating pending randomized trials.
In balloon-uncrossable calcified lesions, rotational atherectomy (RA) is the first-line modality to enable operators to advance balloons and stents over the stenosis. If the lesion is undilatable after RA, a hybrid approach with additional intracoronary lithotripsy (rotatripsy) can be an effective approach that further modifies the calcified plaque and enables stent delivery.

Aznaouridis et al. (2020) studied this question. Rotatripsy, combining rotational atherectomy and intracoronary lithotripsy, effectively modifies calcified plaque and enables stent delivery in undilatable, heavily calcified coronary lesions.
