Novel method for diagnosing takotsubo syndrome with left ventriculography using a microaxial flow pump in temporary surgical mode in a patient with cardiogenic shock: a case report

Coronary angiography and LVG are considered essential diagnostic tools to confirm TTS and exclude acute myocardial infarction. Left ventriculography with Impella temporarily set to surgical mode was able to clearly evaluate LV wall motion abnormalities without affecting haemodynamics. This case highlights that it is perfectly acceptable to prioritize Impella insertion over coronary angiography and LVG in patients with refractory cardiogenic shock in whom the differentiation between TTS and acute myocardial infarction has not yet been made.
