title: Transient left ventricular apical ballooning during dobutamine myocardial perfusion imaging.
abstract: The transient left ventricular apical ballooning is characterized by wall motion abnormalities involving the apex in the absence of obstructive coronary disease. It is precipitated by acute emotional or physical stress and is most often reported in post-menopausal women. We report a case of transient left ventricular "apical ballooning" without significant coronary artery disease precipitated by high dose dobutamine infusion during pharmacological stress myocardial perfusion imaging. The unique feature of our case was precipitation by chemical stress rather than emotional/physical stress.
