Atypical "mid-ventricular" Tako-tsubo cardiomyopathy in a patient suffering from posttraumatic stress disorder: A case report.

The syndrome of "left ventricular ballooning" summarizes an acute onset of transient extensive akinesia of several segments (apical, mid-ventricular) of the left ventricle, without significant lesions on the coronary angiogram, accompanied by chest symptoms, electrocardiographic changes, and limited release of cardiac markers disproportionate to the extent of akinesia. Initially, the vast majority of cases has been reported among Japanese population. Emotional or physical stress or other preceding triggering factors might play a key role in this reversible form of cardiomyopathy, but the precise etiology remains unknown. We describe a case of a 52-year-old woman with posttraumatic stress disorder after cerebral bleeding presenting with an atypical form of left ventricular ballooning ("midventricular ballooning") syndrome.
