STUDY OF MORPHOLOGICAL SIGNIFICANTLY CORONARY ARTERY STENOSIS BEFORE PERCUTANEOUS CORONARY INTERVENTION USING OPTICAL COHERENCE TOMOGRAPHY (OCT) IN KIEN GIANG GENERAL HOSPITAL
Main Article Content
Abstract
Background: Optical coherence tomography is a high-resolution imaging modality that can lead to determine accurately lesions morphology, length, proximal and distal reference diameter. Objectives: To determine injuries morpholgy, length, proximal and distal lesion reference diameter. Methods: A discriptive study from April 2022 to May 2023 in Kien Giang General Hospital, all patients with significant coronary artery narrowing that need percutaneous coronary intertervention were enrolled. Results: In total, 28 lesions in 27 patients were analyzed. Mean age 63.5 ± 2.26, with 33.33% female. The rate of coronary lesions morphology comprised of calcified plaque was 71.42%, lipid plaque was 32.14%, fibrous plaque was 57.14%, red thrombus was 10.71%, white thrombus was 0%, and dissection was 21.43%. Mean lesions length was 39.43 ± 3.71mm. Mean distal and proximal reference diameter was 2.85 ± 0.98mm and 3.62 ± 0.12mm, respectively. Conclusions: Percutanous coronary intervention using optical coherence tomography to help to determine coronary artery lesion morphology, lesion length and lesion reference diameter. Optical Coherence Tomography also helped to find a precise PCI strategy such as stent selection, balloon selection and other supporting equipments.
