Takotsubo syndrome (TTS), also referred to as stress cardiomyopathy, is characterized by transient left ventricular apical ballooning in the absence of obstructive coronary artery disease. Catecholamine-induced cardiac injury or vasospasm has been implicated in this pathophysiology. We present a case of a 67-year-old man 10 years after heart transplantation diagnosed with TTS. Sympathetic reinnervation could not be detected by iodine-123 meta iodobenzylguanidine uptake, suggesting that TTS can occur in the absence of functional sympathetic nerve systems reconstruction.
