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