Abstract

Objective: Evaluate the feasibility, safety, and role of intravascular optical coherence tomography (OCT) for optimal guidance in coronary artery intervention patients. Subjects and methods: Twenty-five patients diagnosed with coronary artery disease and indicated for coronary intervention, inpatient treatment at the Department of Cardiology, Tam Anh Hospital, from April 2022 to October 2023. Intravascular images were analyzed before and after intervention using coronary optical computed tomography (OCT). Results: The average age is 49.12 ± 9.07 years; males account for 68%. The technique is safe, with no complications such as major cardiovascular events (MACE) during the hospital stay. OCT plays a role in guiding intervention optimization through high achievement criteria, in which the smallest lumen area in the stent lumen is 5.79 ± 1.11 mm2; Stent expansion rate achieved 85.89±17.25%; 92% met the criteria of no stent edge separation; 88% met the criteria of 88% vessel wall pressure; 96% met the lesion coverage criteria; 80% met the criteria for parenchymal stent failure. The proportion of patients meeting all criteria for optimal stent outcomes is 68%; calcified lesions increase the risk of difficulty achieving optimal results with odds ratio OR=16.80 (95% CI: 1,62-174.52, p<0.05). Conclusion: Intravascular optical tomography is a safe and feasible technique to evaluate coronary artery lesions with highly optimized results.
