Abstract

Background: Heavy calcified coronary artery stenosis was challenging for interventional cardiologists performing percutaneous coronary intervention (PCI) optimizations and this affected the long-term outcome of patients. Objective: To evaluate the success of PCI procedure in heavily calcified coronary artery stenosis. This needed rotational atherectomy and it caused procedural complications. Materials and methods: A cross-sectional descriptive study on 42 patients with heavily calcified coronary artery diseases that underwent rotational atherectomy at Kien Giang General Hospital from January 2023 to April 2024. Results: average age was 72.7 years old, 52.4% of patients was male, 61.9% had stable angina, 7.2% had unstable angina, 7.2% had non ST elevation myocardial infarction and 9.5% had heart failure. Rotational atherectomy was performed in 90.5% of Left Anteroir Descending (LAD) and 31.3% of the calcified coronary artery diseases were classified by IVUS/OCT imaging. The most common burr diameter of rotational atherectomy was 1.25 mm in 85.7% of cases, but in 14.3% of cases, a burr diameter of 1.5mm was used. Procedural and clinical success was 100%. There were no complications such as coronary perforation or cardiac death. Entrapped burr only occurred in 2.4% of cases. Conclusion: 42 cases of heavily calcified coronory artery stenosis were performed with rotational atherectomy at Kien Giang general hospital. There was a high success rate and a low complication rate.
