Rota-Tripsy or step-up-approach rotational atherectomy for severe coronary artery calcification treatment: a comparative effectiveness study.

ABSTRACT: Step-up-approach rotational atherectomy has been widely recognized in the treatment of severe calcified plaques. As an alternative, the rota-tripsy procedure is a novel strategy for the modification of calcification lesions. This study aimed to evaluate and compare the efficacy and safety of rota-tripsy and step-up-approach rotational atherectomy, given the limited clinical data available. Clinical data of 3652 patients with coronary calcification were retrospectively collected from February 2021 to February 2024. The cases were divided into two groups based on the technical approach. The primary efficacy endpoint was procedural success (stent expansion rate > 70% and no hospital major adverse cardiac events [MACEs]). The primary safety endpoint was the absence of serious angiographic comp
