Key result
Coronary angiography with an ergonovine provocation test was followed 7 days later by Takotsubo cardiomyopathy complicated by left ventricular outflow tract obstruction and cardiac tamponade.
Case Report (n=1)
This case highlights that Takotsubo cardiomyopathy induced by coronary angiography and ergonovine provocation can rarely be complicated by left ventricular outflow tract obstruction and cardiac tamponade.
Possible delayed Takotsubo after ergonovine testing warrants vigilance; leaves open causality in this single case.
Takotsubo cardiomyopathy (TCM) is a transient left ventricular dysfunction that typically occurs after emotional or physical stress. TCM has a benign prognosis and serious complications are uncommon. However, though very rarely reported, cardiac tamponade has occurred on some occasions. We hereby report the case of a 70-year-old woman who underwent coronary angiography with an ergonovine provocation test to evaluate recurrent chest pain and was readmitted 7 days later presenting with TCM, followed by left ventricular outflow tract obstruction and cardiac tamponade.

Kang et al. (2017) conducted a case report in Takotsubo cardiomyopathy complicated with cardiac tamponade (n=1). Coronary angiography with ergonovine provocation test was evaluated on Takotsubo cardiomyopathy followed by left ventricular outflow tract obstruction and cardiac tamponade. Coronary angiography with an ergonovine provocation test was followed 7 days later by Takotsubo cardiomyopathy complicated by left ventricular outflow tract obstruction and cardiac tamponade.
