Analysis of Post-Systolic Shortening, Myocardial Strain, and Arterial Flow to Assess Myocardial Ischemia during Stress Echocardiography
Arq Bras Cardiol: Imagem cardiovasc. 2020;33(3):abc63
Video 1 - Before hemodynamic intervention. In the 4-chamber apical record, the left ventricle shows normal contractility during dobutamine stress echocardiography at
submaximal heart rate.
Video 2 - Before hemodynamic intervention. In the 2-chamber apical record during dobutamine stress echocardiography, the left ventricle presents a contractile abnormality
compatible with ischemia in the inferior wall (below left) in submaximal heart rate. Ischemia is most evident in the recovery phase (bottom right)
Video 3 - After hemodynamic intervention. In the 4-chamber apical record, the left ventricle presents normal contractility during dobutamine stress echocardiography
at maximum heart rate.
Video 4 - After hemodynamic intervention. In the 2-chamber apical record, the left ventricle presents normal contractility during dobutamine stress echocardiography
at maximum heart rate
