Abstract

Background: Heavily calcified coronary artery stenosis are a high risk lesions in optimising treatment and predictor of successful percutaneous coronary intervention procedure was low. Objective: Evaluate to heavily coronary artery lesions for the treatment strategies with special devices and find out the risk factors associated with coronary artery calcification. Materials and methods: A cross-sectional descriptive study on 260 patients with narrowing coronary artery diseases that underwent percutaneous coronary intervention at Kien Giang General Hospital from January 2023 to April 2024. Results: The average age was 67.3 years old, 52.4% of patients was male. Evaluating the calcification by angiography for 95.4% of cases, by IVUS for 2.3% of cases, by OCT for 2.3% of cases. Patients with ≥ 2 coronary artery stenosis were 62.2% of cases. The LAD branch had a calcification rate of 31.2% of cases, the RCA branch had a calcification rate of 17.3% of cases, the LCx branch had a calcification rate of 12.7% of cases and the LMCA branch had a calcification rate of 5.8% of cases. The patients with moderate to severe calcified coronary artery were 31.1% of cases. Multi-vessel coronary artery disease is associated with heavily coronary artery calcium with statistically significant (p<0,0005). Successful percutaneous coronary intervention in heavily coronary artery calcium with special devices such as cutting balloons, rotational atherectomy. There were 40/44 (78.4%) of patients performed with rotational atherectomy, of which 5 cases were performed a recuse rotational atherectomy due to unexpansion lesion  with balloons for predilatation. There was one case of trapping burr, but it was resolved successfully. Conclusion: Up to 1/3 of cases in percutaneous coronary intervention with moderate to severe calcium requiring special devices such as rotational atherectomy, cutting balloons. 42 cases of heavily calcified coronary artery stenosis were performed with rotational atherectomy at Kien Giang general hospital. There was a high success rate and a low complication rate.
