Syndrome Tako-tsubo au décours d'une perfusion d'immunoglobuline humaine normale (Tégeline®)

This is a case of an 82 year old female patient with myasthenia gravis, who following treatment with Human Normal Immunoglobulin (Tegeline®), developed dyspnoea, chest pain without cardiac insufficiency, inverted T wave on ECG with slight increase in Troponine T 0.43 ng/mL (< 0.2 ng/mL normal value in our hospital) and marked increase in Pro-BNP 4900 (Nl ≤ 450 pg/mL for an age greater than 65 years old). Her coronary angiogram showed hypokinesia of apical area but was otherwise normal. Also, MRI ruled out inflammatory and ischemic cardiac diseases. The most likely diagnosis for us was Tako-Tsubo syndrome in relation with injection of Human Normal Immunoglobulin (Tegeline®) according to the Mayo clinic criteria.
