Video Acute Onset of Stress Cardiomyopathy During Dobutamine Stress Echocardiography
Standard transthoracic views obtained during a dobutamine stress echocardiogram at baseline (Video 1), peak dobutamine infusion (Video 2), and post-dobutamine infusion (Video 3) in patient #1. The views demonstrated in all 3 videos include parasternal long-axis (top left), short-axis (top right), apical 4-chamber (bottom left), and apical 2-chamber (bottom right). Baseline images (Video 1) show normal left ventricular systolic function. At peak dobutamine infusion (Video 2), there is severe mid-ventricular and apical hypokinesis that persists into recovery (Video 3). Cardiac catheterization 2 days later revealed normal coronary arteries and recovery of left ventricular systolic function.
