Abstract

Background: Transradial coronary artery intervention is the most commonly used method for revascularization in coronary artery disease. Since 2020, Kien Giang Provincial General Hospital has equipped the Rotablator atherectomy system and has been gradually implementing this procedure for indicated patients. Objectives: Surveying the characteristics of injury and treatment outcomes of coronary artery intervention with Rotablator atherectomy in patients with coronary artery disease at Kien Giang Provincial General Hospital. Materials and methods: We selected 260 patients with coronary artery disease (CAD), including 40 patients indicated for Rotablator atherectomy for coronary atherosclerosis. Results: The average age of the study population was 67,33 ± 10,34 years, with males accounting for 55,8%. The majority of patients had a history of hypertension (84,9%) and coronary artery disease (70,4%). CCS class III angina was present in 50,8% of cases, and 78,2% had no heart failure. Single-vessel, two-vessel, and three-vessel coronary artery disease were observed in 37,7%, 24,2%, and 38,1% of cases, respectively, with 65,8% showing no calcification. The most common lesion location was the left anterior descending artery (86,9%), followed by the right coronary artery (67,7%) and circumflex artery (55,8%). Rotablator atherectomy was initially performed in 87,5% of patients. The transradial approach was used in 99,6% of cases, with 6F guiding catheters in 99,2%. All patients used a single burr, with a 1,25 mm size in 87,5% of cases. The mean drilling speed was 181750 ± 4425,31 rotations per minute, and the total drilling time averaged 53,1 ± 23,29 seconds. Treatment success rate was 100%, with few complications observed during the procedure. Conclusion: The majority of patients with coronary artery disease have complex lesions involving multiple coronary arteries. All patients with coronary artery disease who underwent Rotablator atherectomy intervention were successful, with few complications observed during the procedure.
