Comparison of optical coherence tomography and quantitative coronary angiography for vessel sizing and stent optimization in percutaneous coronary intervention
Main Article Content
Abstract
Optical coherence tomography (OCT) provides more detailed visualization of the coronary lumen and vessel wall structure than quantitative coronary angiography (QCA); however, data from Vietnam remain limited. This study aimed to compare vessel measurements obtained by OCT and QCA and to evaluate the role of OCT in optimizing stent implantation. A cross-sectional study was conducted in 160 patients with 185 coronary lesions undergoing percutaneous coronary intervention at Kien Giang General Hospital. The results showed that measurements obtained by OCT were consistently higher than those obtained by QCA, including proximal reference diameter (3.39 ± 0.65 mm vs 3.21 ± 0.64 mm), distal reference diameter (2.77 ± 0.65 mm vs 2.65 ± 0.59 mm), and lesion length (37.96 ± 16.46 mm vs 35.13 ± 14.62 mm) (p < 0.001). Significant positive correlations were observed between OCT and QCA measurements (r = 0.628 and r = 0.795, p < 0.001). These findings indicate that OCT allows detailed assessment of plaque morphology and supports optimization of stent implantation during coronary intervention.
