Why the study?
What are the normal reference ranges for proximal aorta dimensions assessed by two-dimensional transthoracic echocardiography?
What are the normal reference ranges for proximal aorta dimensions assessed by two-dimensional transthoracic echocardiography?
The study establishes normal reference ranges for proximal aorta dimensions using 2D echocardiography, noting that age, gender, and body size significantly affect these measurements.
Answers are grounded in this paper and cite their sources.
May guide echo interpretation of aortic dimensions accounting for age, gender, and size; leaves open prospective validation before routine adoption.
The NORRE study provides normal values of proximal aorta dimensions as assessed by echocardiography. Reference ranges for different anatomical levels using different (i) measurement conventions and (ii) at different times of the cardiac cycle (i.e. mid-systole and end-diastole) are provided. Age, gender, and body size were significant determinants of aortic dimensions.
