EFFICACY AND SAFETY OF ROTATIONAL ATHERECTOMY BY ROTABLATOR IN PERCUTANEOUS CORONARY INTERVENTION
Main Article Content
Abstract
Background: Rotational atherectomy (RA) is an adjunctive method in percutaneous coronary intervention (PCI) for calcified lesions. However, there remains considerable debate regarding the procedural approach, efficacy, and safety of this technique. Objectives: To investigate the implementation and evaluate the efficacy and safety of rotational atherectomy using the Rotablator system in PCI. Subject – method of study: This observational, retrospective study was conducted on 223 cases that underwent RA using the Rotablator system at the University Medical Center Ho Chi Minh City from January 1, 2019, to October 31, 2023. Results: The average age of the study population was 69.5±9.6 years, with 59.6% being male. Acute coronary syndrome was the cause of admission in 78.9% of patients, with three-vessel coronary artery disease (CAD) accounting for 74.9% of cases. The most common target lesion site was the left anterior descending artery (66.4%). Intravascular ultrasound (IVUS) was used in 93.6% of cases. Primary RA strategy was employed in 67.7% of cases. Angiographic success was achieved in 96.4% of cases. Procedural complications included coronary perforation (2.2%), coronary dissection (2.2%), slow or no-reflow (4.0%), and acute cardiac tamponade (0.9%). In-hospital major adverse cardiovascular events (MACEs) occurred in 8.5% of patients, mainly due to periprocedural myocardial infarction (5.8%). Conclusion: Our study demonstrates that rotational atherectomy using the Rotablator system in PCI is a safe and effective treatment method with a high success rate.
