Parametric cardiovascular magnetic resonance imaging in takotsubo syndrome: a case report

TL;DR

This case report shows that cardiovascular magnetic resonance imaging can reveal late gadolinium enhancement in takotsubo syndrome, challenging previous assumptions.

Contribution

The paper presents a novel case of takotsubo syndrome with late gadolinium enhancement detected via parametric CMR.

Findings

Late gadolinium enhancement was observed in a takotsubo syndrome case using CMR.

Parametric T1/T2 mapping showed myocardial changes matching wall motion abnormalities.

CMR can aid in diagnosing myocardial infarction with non-obstructed coronary arteries.

Abstract

Takotsubo syndrome (TTS) causes angina with ventricular dysfunction that can mimic acute coronary syndrome. Normal coronary angiography leads to cardiovascular magnetic resonance imaging (CMR) in the diagnostic pathway. Historically, TTS was thought to be associated with the absence of late gadolinium enhancement on CMR. This case report highlights the presence of late gadolinium enhancement in a case of TTS while demonstrating the other characteristic findings, including quantitative parametric T1/T2 mapping.

A 69-year-old lady was admitted with chest pain and shortness of breath. She was found to have classical TTS with the characteristic wall motion abnormalities on echocardiogram, left ventricular angiogram, and CMR. Her CMR also demonstrated strongly positive myocardial T1/T2 mapping that matched the wall motion abnormalities and the less frequently described positive early and late gadolinium enhancement.

This case highlights the diagnostic pathway in TTS and the ability of CMR to make a diagnosis in myocardial infarction with non-obstructed coronary arteries. We describe the characteristic cardiac imaging features of TTS while discussing the positive late gadolinium enhancement patterns that may help confirm the diagnosis.
