[Atypical form of tako-tsubo cardiomyopathy in a patient with atrial fibrillation in Wolff-Parkinson-White syndrome complicated with ventricular fibrillation: the diagnostic problems].
Atypical form of tako-tsubo cardiomyopathy (TTC) is associated with regional wall motion abnormalities in basal and/or middle segments or only middle segments with sparing of apical segments or apical and basal segments. We described a case of47-year-old female with atypical form of TTC due to fast atrial fibrillation that converted into ventricular fibrillation in WPW syndrome. The echocardiogram made after direct current cardioversion revealed decreased left ventricular ejection fraction (LVEF 35%) with akinesis of inferior and posterior walls and anterior part of interventricular septum in the middle and the basal segments with hyperkinesis of apical segments. The biochemistry blood samples revealed elevated both troponin T- 0.35 ng/mL and NT-proBNP - 3550 pg/mL plasma level. The ECG showed sinus rhythm 62 bpm, shortened PQ interval 100 ms, widened QRS duration - 115 ms with delta wave, prolonged QT interval - 520 ms, QS in leads: II, III, aVF. NegativeT waves in leads: I, aVL and positive, symmetrical T waves in leads V1-V6. The coronarography revealed normal coronaryarteries. The control echocardiography after 10 days showed normal LVEF 70%, without any wall motion abnormalities. TTC was recognised based on: history of sudden stress situation before, ischaemic ECG changes, positive markers of myocardial injury, transient segmental wall motion abnormalities and normal coronary arteries. The ablation of right postero-septal accessory pathway was successfully performed.
