Key result
Biplane strain imaging was feasible for measuring cumulative strain in a dog model of aortic stenosis, showing that maximum strain decreased by 50% with increasing valvular stenosis.
Population
4 dogs (beagles) with aortic stenosis (animal model of a child's heart)

Does not support clinical adoption; leaves open translation of biplane strain imaging to human aortic stenosis.
Biplane strain imaging using a commercial ultrasound system is feasible for assessing radial, circumferential, and longitudinal strains simultaneously in an animal model of aortic stenosis.
Lopata et al. (2010) studied Aortic stenosis (n=4). Biplane strain imaging was evaluated on Feasibility of measuring radial, circumferential and longitudinal cumulative strain. Biplane strain imaging was feasible for measuring cumulative strain in a dog model of aortic stenosis, showing that maximum strain decreased by 50% with increasing valvular stenosis.
