Insights
Intravascular ultrasound (IVUS) reveals significant differences in coronary artery ostia dimensions between men and women in Ukraine. Men exhibit larger diameters and lumen areas, highlighting the importance of morphological evaluation in interpreting these cardiac images.
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
- Human Anatomy
Background:
- Coronary artery ostia morphometry is crucial for understanding cardiovascular health.
- Intravascular ultrasound (IVUS) provides detailed imaging of coronary artery anatomy.
- Previous studies have indicated potential sex-based differences in coronary vasculature.
Purpose of the Study:
- To conduct a morphometric assessment of coronary artery ostia using IVUS in the Ukrainian population.
- To evaluate morphological characteristics and identify potential sex-based differences.
Main Methods:
- Analysis of intravascular ultrasound images of the right and left coronary artery ostia from 25 patients.
- Measurements included minimum diameter, maximum diameter, mean diameter, and lumen area.
- IVUS procedures were performed prior to percutaneous coronary intervention.
Main Results:
- Significant differences in maximal diameter, mean diameter, and lumen area were observed between men and women (p<0.0001).
- Men demonstrated larger maximal diameters in both the right coronary artery (RCA) and left coronary artery (LCA) ostia compared to women.
- While RCA ostia were larger than LCA ostia in women, these differences were not statistically significant.
Conclusions:
- IVUS analysis revealed significantly larger dimensions (minimum diameter, mean diameter, maximum diameter, lumen area) of coronary artery ostia in men compared to women within the Ukrainian population.
- Morphological evaluation is essential for accurate interpretation of intracoronary images, especially when assessing sex-based variations.
Objective:
The aim: To perform a morphometric assessment of the coronary arteries ostia by intravascular ultrasound with morphological evaluation among the Ukrainian population.
Patients And Methods:
Materials and methods: Intravascular images of the ostia of the right (48%) and left (52%) coronary arteries with the minimum diameter, maximum diameter, mean diameter and lumen area were analyzed. An intravascular ultrasound procedure was performed before percutaneous intervention.
Results:
Results: A total of 25 IVUS examinations were collected from patients of both sexes and the same ages: 61,27±10,24 for males and females 68±5,83 (p=0.64).The left coronary artery (LCA) ostium assessment was performed in 13 (52%) cases: 8 men and 5 women (32% and 20%, respectively). The right coronary artery (RCA) ostium assessment was performed in 12 (48%) cases: 7 men and 5 women (28% and 20%, respectively). The maximal diameter of the coronary artery ostia was higher in men (5.95±0.66mm) than in women (4.82±0.34mm) (p<0.0001). In men, the maximal diameter of the RCA was higher than in the LCA (6.4±0.40mm and 5.56±0.60mm, respectively). The same differences were found in the mean diameter and lumen area (p<0.05). In women, the minimum diameter, mean diameter, maximum diameter and lumen area of the RCA were higher than LCA but without statistically signi#cant di"erences. The anatomic precondition explains the observed changes in echogenicity.
Conclusion:
Conclusions: IVUS analysis shows signi#cantly higher parameters of the minimum diameter, mean diameter, maximum diameter and lumen area in men than in women among the Ukrainian population. Therefore, morphological evaluation is crucial in the interpretation of intracoronary images.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
