Correlations between echocardiography and cardiovascular magnetic resonance in a patient with midventricular stress cardiomyopathy.

MOTS CLÉS Cardiomyopathie induite par le stress ; A 73-year-old woman without previous medical history was admitted for suspected persistent thoracic anginal pain following a violent suffocating cough. On admission, results of physical examination and per-critical electrocardiogram were normal. Aortic dissection and pulmonary embolism were ruled out by computed tomography scan. The troponin peak reached 3.55 g/l at day one, while an electrocardiogram showed T-wave inversion in the anterior and lateral leads. A transthoracic echocardiogram showed akinesis of the midportion of the lateral, posterior, anteroseptal and anterior walls of the left ventricle while the apical and basal parts of these walls were normocontractile (Panel A) and left ventricular ejection fraction was at 40%. Coronary angiography was normal. Cardiovascular magnetic resonance (CMR) confirmed echocardiographic findings with wall motion abnormalities confined to the midportion (Panel B). High T2 signal was observed within the asynergic myocardium (Panel C) while no regional delayed gadolinium hyperenhancement
