Miocardiopatía de takotsubo en la fase de recuperación de ecocardiografía de estrés con dobutaminaTakotsubo cardiomyopathy in recovery phase during dobutamine stress echocardiogram. Rev. Colomb.

Dobutamine stress echocardiogram is one of the most frequently used methods to assess the presence of induces ischaemia with a high level of certainty. There are few reports of takotsubo cardiomyopathy during the recovery phase of this test. We present the case of a 56 year-old female who was admitted for a dobutamine stress echocardiogram as part of a chest pain evaluation. Baseline assessment showed normal contractibility, ejection fraction 60 % and normal electrocardiogram. At a dobutamine dose of 30 μ¼g/kg she started feeling crushing chest pain associated to a complete left bundle-branch block, without associated alterations or contractibility. During the recovery phase she developed akinesia of all mid and apical segments with an increase in volumes and a persistence of the left bundle-branch block. A coronary angiography was performed, showing healthy epicardial vessels. Six weeks later the full recovery from the contractibility was evidenced on the electrocardiogram, as well as the disappearance of the left bundle-branch block. Takotsubo cardiomyopathy can be included as a frequent complication of the dobutamine stress echocardiogram, both during the highest stress period as well as during the recovery phase.
