Abstract:
Takotsubo cardiomyopathy (TTC) is a recently recognized clinical syndrome characterized by transient ventricular dysfunction in the absence of obstructive coronary artery disease. TTC primarily affects postmenopausal women; TTC in children and adolescents is only rarely reported. Furthermore, simultaneous occurrence of Takotsubo cardiomyopathy and primary electrical diseases has been previously reported in only four recent cases of female patients with congenital long QT syndrome. Here, we report the novel association of catecholaminergic polymorphic ventricular tachycardias and a midventricular type of TTC observed in a young female patient.
