Summary
This study quantitatively measured right auricular morphology in healthy individuals using MDCTA. Men showed significantly larger measurements than women, and age influenced specific parameters, aiding cardiac intervention understanding.
Area of Science:
- Cardiovascular Imaging
- Anatomy
- Medical Diagnostics
Background:
- The right auricle's morphology is crucial for understanding cardiac function and guiding interventions.
- Quantitative data on right auricular dimensions in healthy populations are essential for comparative analysis.
Purpose of the Study:
- To quantitatively measure the morphology parameters of the right auricle in healthy individuals using 256-slice multidetector computed tomography angiography (MDCTA).
Main Methods:
- Retrospective analysis of 200 patients who underwent coronary MDCTA with negative findings.
- Quantitative measurement of right auricular and atrial volumes, dimensions, angles, and distances from reconstructed imaging data.
Main Results:
- Men exhibited significantly larger right auricular volume, height, base long axis, area, perimeter, and normal distance compared to women (P < 0.05).
- Age over 40 was associated with significantly smaller normal angle and distance (P < 0.05).
- Right auricular parameters showed good correlation with right atrium volume, aortic diameter, body weight, height, and body surface area.
Conclusions:
- Quantitative MDCTA measurements provide valuable insights into right auricular morphology and its spatial relationships.
- These findings support improved understanding for cardiac electrophysiology interventions and radiofrequency ablation procedures.
