Summary
We present the case of a 61-year-old woman admitted with chest pain and an ECG demonstrating ST-segment elevation in the lateral leads. Emergency coronary angiography demonstrated an occluded obtuse marginal branch. Percutaneous intervention was unsuccessful as the lesion could not be crossed with a wire. Left ventriculography and transthoracic echocardiography demonstrated hypokinesis of the entire apex but preserved contractility of the basal segments, consistent with a diagnosis of apical ballooning syndrome (ABS). Cardiac MRI demonstrated myocardial oedema in all mid to apical segments, with a left ventricular ejection fraction (LVEF) of 38%. Repeat study at 5 months demonstrated an infarct in the distribution of the occluded artery with late gadolinium enhancement, consistent with a diagnosis of a lateral wall myocardial infarction and an improvement in the LVEF to 51%. The case illustrates the novel observation that ABS and acute myocardial infarction may rarely occur simultaneously.
