Two-dimensional longitudinal strain in patients with aortic stenosis can be reliably acquired at the bedside without additional benefit of offline analysis.

Background: Two-dimensional strain echocardiography (2DS) has been used to assess ventricular function in several disease states. In previous studies of 2DS, strain analysis was usually performed offline by experienced echocardiographers. The applicability of 2DS in busy clinical labs would be enhanced if 2DS could be reproducibly measured by sonographers at the time of the echo exam.
