Abstract

Takotsubo syndrome is characterized by transient and regional left ventricular dysfunction, which does not correspond anatomically to coronary distribution, without obstructive coronary lesions and frequently follows episodes of emotional or physical stress. The authors present a case of takotsubo syndrome, complicated by acute heart failure and functional severe mitral regurgitation, in a newborn after fetal distress caused by the umbilical cord being twisted around the chest and neck. In newborns after birth asphyxia, left ventricular dysfunction has been reported as global and due to ischemia. In this case, the transient and regional left ventricular dysfunction involving segments of multiple epicardial coronary territories, with associated hyperkinesis of the ventricular septum and basal segments of other walls, could have been caused by delivery stress with catecholamine-mediated cardiac toxicity.
