Impact of Calcified Lesion Complexity on the Success of Percutaneous Coronary Intervention With Upfront High-Speed Rotational Atherectomy or Modified Balloons - PREPARE-CALC Subgroup-Analysis
Abstract
Background/purpose
In the randomized PREPARE-CALC trial, lesion preparation of calcified lesions with upfront rotational atherectomy (RA) prior to drug-eluting stent (DES) implantation resulted in higher acute success as compared to a provisional modified balloon (MB) strategy. We aimed to investigate the impact of calcified lesion complexity on the treatment effect with either MB or RA.
