Takotsubo cardiomyopathy after solid organ transplantation: a scoping review.

ABSTRACT

Takotsubo syndrome (TTS) is a stress-induced cardiomyopathy that causes temporary left ventricular wall motion abnormalities and abrupt reversible heart failure. The incidence of perioperative TTS is proportional to the severity of surgical trauma, the duration of the procedure, and the degree of apparent sympathetic activity. A growing number of articles have discussed TTS after a solid organ transplant (SOT), which is one of the circumstances in which physical and emotional stress are at their highest levels. The majority of published cases involved patients who had received an orthotopic liver transplant (OLT). TTS occurred in 0.3-1.7% of liver transplant recipients, but a limited number of cases of TTS in patients who had received kidney, heart, or lung transplants have also been documented. In this study, we analyzed the TTS instances that developed after SOT, highlighting the symptoms and causes as well as the various treatment approaches that were applied. Most TTS cases following OLT and kidney transplant cases occurred in the first week of the surgery. However, the majority of cases occurred years after heart transplantation. Dizziness, dyspnoea, and chest discomfort are the most typical symptoms. Patients may also experience syncope and generalized weakness. In spite of this, the symptoms differ depending on the transplanted organ. Dyspnoea is a common symptom after lung transplants, whereas chest discomfort and dizziness are a common symptom after liver and kidney transplants. Yet, chest pain is not a typical symptom after a heart transplant.
