Key result
Two-dimensional right parasternal echocardiography visualized a larger maximum length of the ascending aorta compared to the left parasternal approach in 87% of patients (P < 0.001).
Why the study?
The ascending aorta has not been well studied using two-dimensional right parasternal transthoracic echocardiographic examination.
Does right parasternal transthoracic echocardiography (2D and 3D) improve the assessment of ascending aorta size compared to the left parasternal approach in adult patients?

Does right parasternal transthoracic echocardiography (2D and 3D) improve the assessment of ascending aorta size compared to the left parasternal approach in adult patients?
Right parasternal echocardiography, particularly with 3D imaging, provides superior visualization and larger measurements of the ascending aorta compared to the standard left parasternal approach.
BACKGROUND: The ascending aorta (AA) has not been well studied using two-dimensional right parasternal transthoracic echocardiographic examination (2DRPE). AIM: The aim of the present study was to assess the incremental value of 2DRPE over two-dimensional left parasternal transthoracic echocardiographic examination (2DLPE) in evaluating the size of AA in adult patients (pts) and, secondly, to determine whether live/real time three-dimensional (3D) RPE provided any additional benefit over 2DRPE. MATERIALS AND METHODS: The AA was successfully imaged by 2DLPE, 2DRPE, and 3D RPE in 87 of 141 (61.7%) pts which comprised of two groups of consecutive pts separated by an interval of 2 weeks. RESULTS: The maximum length of AA visualized by 2DRPE (4.98 ± 0.89) was larger than 2DLPE in 76/87(87%) pts (P < 0.001). Both the maximum systolic AA inner luminal width and leading edge-to-leading edge width by 2DRPE were greater than 2DLPE (P < 0.001). Similar to other noninvasive imaging modalities where mid-AA width is taken at level of right pulmonary artery, mid-AA width could also be taken at this level by 2DRPE in 79/87(91%) pts since this landmark was visualized during 2DRPE. However, this vessel could be visualized in only 2/87 (2%) pts with 2DLPE. 3DRPE conferred additional benefit over 2DRPE. The maximal AA length by 3DRPE was larger than 2DRPE in 60/87(69%) pts, and the maximal inner lumen and leading edge to leading edge widths were larger in 54/87(62%) and 66/87(76%) pts, respectively. CONCLUSION: Our preliminary study demonstrates significant incremental value of 2DRPE over 2DLPE in the assessment of AA. 3DRPE confers an additional advantage over 2DRPE.

Akdogan et al. (2019) conducted an observational in Ascending aorta size assessment (n=141). Two-dimensional right parasternal transthoracic echocardiography (2DRPE) vs. Two-dimensional left parasternal transthoracic echocardiography (2DLPE) was evaluated on Maximum length of ascending aorta visualized (p=< 0.001). Two-dimensional right parasternal echocardiography visualized a larger maximum length of the ascending aorta compared to the left parasternal approach in 87% of patients (P < 0.001).
