Abstract:Objective:To explore the safety of coronary rotablation in patients with severe left ventricular systolic dysfunction. Methods:From January 2016 to December 2019, 14 patients undergoing coronary rotablation in Zhongshan Hospital were retrospectively enrolled in this study. Results:Average age of patients were (68.5±8.6) years old, and mean LVEF was (31.4±2.6)%. It took (4.9 ±2.4) times to pass through the lesion, and the average maximal speed was (18.2±1.8)×10⁴ r/min. Drug eluting stents were successfully implanted in all patients, with an average of (2.9±1.2) stents per patient. One case (7.1%) developed slow blood flow, 2 cases (14.3%) developed coronary artery dissection, and 2 cases (14.3%) developed coronary spasm. All of them were diffuse calcified lesions, which were resolved by drug treatment or stent implantation. No coronary perforation, pericardial tamponade, emergency surgery or death occurred. No major adverse cardiac events occurred during hospitalization. Conclusions:Coronary rotablation in patients with severe left ventricular systolic dysfunction was safe.
