Abstract
ObjectivesThe aim of this study is to assess the feasibility, efficacy and safety of the “RotaTripsy” approach in severe calcified coronary artery lesions. BackgroundCoronary lesions with a high calcium content represent a challenging scenario in interventional cardiology, requiring a proper lesion preparation. In this light, very little is known about the possibility to combine the benefits of rotational atherectomy and intravascular lithotripsy. MethodsWe retrospectively enrolled 34 patients from a real-word, multicenter, cohort of patients affected by severe calcified coronary artery lesions, which required the “RotaTripsy” to obtain a proper lesion preparation. In all the cases, rotational atherectomy and then intravascular lithotripsy were performed as a bail-out strategy following sub-optimal non-compliant balloon expansion. In 53% of the cases, the procedure was guided by intracoronary imaging findings. ResultsProcedural success was reported in all the cases, without any in-hospital major complication. Few major adverse clinical events were reported at mid-term follow-up. Conclusions“RotaTripsy” can represent a valid therapeutic option for undilatable heavily calcified coronary artery lesions. Our findings demonstrate the feasibility, safety and efficacy of this approach.
