[Takotsubo-like left ventricular dysfunction with delayed recovery of left ventricular shape: a case report].

A 70-year-old woman was admitted to our hospital because of left ventricular dysfunction, which was observed after permanent pacemaker implantation in another hospital. The left ventricular dysfunction was apical ballooning. Left ventriculography demonstrated takotsubo-like shape. However, the dysfunction did not improve immediately with medical treatment. In this case, 75% stenosis was observed in the left anterior descending artery. We suppose that this lesion corresponded to the delayed recovery of the dysfunction and performed coronary intervention. The takotsubo-like shape improved gradually for about 1 year. Whether the coronary intervention was effective for the recovery of the dysfunction is unclear, this clinical course was interesting in evaluating the delayed recovery of takotsubo-like left ventricular dysfunction.
