Abstract：Objective To evaluate the efficacy and safety of Guidezilla extension catheter assisted rotational atherectomy in the interventional treatment of complex coronary artery calcification lesions.Methods A total of 45 patients with severe coronary artery calcification detected by coronary angiography in Beijing Anzhen Hospital,Capital Medical University from January 2018 to December 2021 were consecutively enrolled.The Guidezilla extension catheter was used to assist rotational atherectomy.The basic clinical data,lesion characteristics,rotational atherectomy treatment,intraoperative complications and major adverse cardiovascular events during hospitalization were analyzed.Results The distribution of coronary artery calcification in 45 patients was mainly the right coronary artery(21 cases,46.7％),the rest included the left anterior descending artery(11 cases,24.4％)and left circumflex artery(13 cases,28.9％).The anatomical features of coronary artery calcification mainly included abnormal opening(9 cases,20.0％),tortuosity of the proximal segment(8 cases,17.8％),and distal lesion(28 cases,62.2％).Rotational atherectomy was successfully performed and stents were implanted in all patients.The length of calcified lesions was(18±6)mm,the rotational speed was(17.1±1.2)×104 r/min,and the rotational time was(1.4±0.4)min.There were no intraoperative complications such as burr incarceration,vascular rupture,severe dissection,and other complications.No major adverse cardiovascular events occurred during hospitalization.Conclusions The Guidezilla extension catheter assisted rotational atherectomy is a safe and effective procedure for the treatment of complex coronary artery calcification lesions.
