Rotational atherectomy combined with cutting balloon to optimise stent expansion in calcified lesions: the ROTA-CUT randomised trial
Authors' conclusion
Combining RA with CBA resulted in a similar minimum stent area compared with RA followed by NCBA in patients undergoing PCI of moderately or severely calcified lesions.
Study context
- Population
- Patients with CAD undergoing percutaneous coronary intervention (PCI) of moderately or severely calcified lesions with drug-eluting stent implantation
- Participants
- 60 patients
- Comparison
- Rotational atherectomy (RA)+CBA vs RA+NCBA
- Primary endpoint
- Minimum stent area on intravascular ultrasound (IVUS)
Methodological detailsprospective, multicentre, 1:1 randomisation
- Prospective
- Multicentre
- 1:1 randomisation
Primary result
As reported in the abstract
Minimum stent area (IVUS)
P = 0.685
Secondary outcomes
Other intravascular ultrasound (IVUS) and angiographic endpoints (minimum lumen area, stent expansion, acute lumen gain, final residual diameter stenosis, minimum lumen diameter)
- No significant differences
