Diagnosis and treatment of Takotsubo syndrome after liver transplantation and literature review / 器官移植

ABSTRACT

Objective To summarize the experience of diagnosis and treatment of Takotsubo syndrome (TTS) after liver transplantation. Methods Clinical data of one TTS patient after liver transplantation was retrospectively analyzed. Clinical features, diagnosis and treatment strategies were summarized, and literature review was conducted. Results A 43-year-old female patient successfully underwent split liver transplantation due to primary biliary cirrhosis for 8 years. At postoperative 3 d, the patient developed anxiety, irritation, dyspnea, disorientation, hypotension, N-terminal pro-brain natriuretic peptide (NT-proBNP) of > 35 000 pg/mL, creatine kinase isoenzyme (CK-MB) of 5.9 U/L and troponin I (TnI) of 1.78 μg/L. Electrocardiogram indicated the signs of sinus rhythm. Echocardiography indicated diffuse weakening of the left ventricular wall motion and spherical dilatation of the apex, accompanied with moderate and severe regurgitation of the mitral valve and tricuspid valve. The left ventricular ejection fraction (LVEF) declined to 23%, whereas no abnormal segmental motion of ventricular wall or corresponding electrocardiogram changes were observed. The possibility of acute coronary syndrome was excluded. The InterTAK diagnostic score was 73. The diagnosis of TTS after liver transplantation was considered. Metoprolol, coenzyme Q10, recombinant human brain natriuretic peptide, deacetyl lanatoside and lorazepam were given. Echocardiography at postoperative 10 d showed that the left ventricular function was significantly improved and the LVEF recovered to 50%. The patient was discharged 40 d after liver transplantation. The liver function was recovered well. During postoperative follow-up, she was given with metoprolol till the submission date, and no recurrence was reported. Conclusions TTS after liver transplantation is rare in clinical practice. It is difficult to make the diagnosis. The condition of TTS is severe and clinical prognosis is poor. Prompt diagnosis and interventions should be implemented.
