Abstract

Ascending aorta dilatation is common in bicuspid aortic valve (BAV). The aim of this study was to investigate agreement of transthoracic echocardiographic (TTE) measurement of the sinuses of Valsalva and the tubular mid-ascending aorta (Asc-Ao) compared with electrocardiographically gated computed tomographic angiographic (CTA) assessment in patients with BAV. Fifty-three patients with BAV (mean age, 54 ± 14 years; 74% men) who underwent both TTE and CTA imaging for ascending aortic assessment were retrospectively identified. All studies were measured de novo by experts. TTE measurements were obtained at the sinuses and the Asc-Ao, at both systole and end-diastole, using both leading edge-to-leading edge (L-L) and inner edge-to-inner edge (I-I) methods in the parasternal long-axis (LAX) view. The sinuses were also measured in the parasternal short-axis (SAX) view using the same methods plus mid-diastole. CTA measurements were obtained in diastole using outer wall-to-outer wall (O-O) and inner wall-to-inner wall (I-I) methods. Correlation and agreement between the two imaging modalities were assessed using Lin correlation and Bland-Altman analysis, respectively. Compared with CTA O-O maximum sinuses diameter, the best correlatio...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.
