Dobutamine stress CMR predicts viable myocardium

Dobutamine stress CMR studies in a patient with total occlusion of the left anterior descending artery and a prior anterior wall myocardial infarction.
(Left upper panel) At rest, the short axis cine CMR at end-diastole shows normal diastolic wall thickness (*).
(Left lower panel) During systole (left lower panel) there is lack of systolic wall thickening (SWT) of the septum and anteroseptal portion of the anterior wall (arrow).
(Middle lower panel) During a dobutamine infusion, there was significant induction of SWT (arrow), indicating viable myocardium.
(Right lower panel) Four months after angioplasty, resting SWT of the anteroseptal region was normal.
