Transthoracic echocardiography a reliable tool for assessing proximal aorta diameters

Transthoracic echocardiography (TTE) appears to be consistent when evaluating proximal aorta diameters in hypertensive patients, a new study shows.

Researchers examined the accuracy of TTE vs cardiac magnetic resonance (CMR) for the evaluation of proximal thoracic aorta diameters in a cohort of hypertensive patients. They recruited 75 essential hypertensive outpatients previously assessed by TTE and then by CMR.

The two techniques were specifically compared at the level of sinuses of Valsalva (SoV) and ascending aorta (Asc) diameter. For the TTE image, researchers compared the inner edge-to-inner edge and leading edge-to-leading edge conventions.

When using the leading edge-to-leading edge convention, TTE and CMR diameters were significantly correlated (SoV: r=0.931; p<0.001; Asc: r=0.949; p<0.001). TTE and CMR diameters had a mean difference of 2.49±2.01 mm at the level of SoV and 1.13±1.77 mm at the level of Asc.

In addition, TTE diameters measured by inner edge-to-inner edge convention also showed good correlation (SoV: r=0.936; p<0.001; Asc: r=0.947; p<0.001).

Inner edge-to-inner edge demonstrated better correlation with CMR measurements than leading edge-to-leading edge, with a good interobserver and intraobserver agreement, based on comparisons of the two techniques in the assessment of Asc.

“Accurate and reproducible measurements of proximal thoracic aorta diameters are essential in the diagnosis and follow-up of patients with aortic dilatation, a condition particularly common in hypertensive patients,” researchers said.
