RESUMO
INTRODUCTION: Takotsubo syndrome (TTS), also known as Takotsubo cardiomyopathy or stress-induced cardiomyopathy, has been described following a variety of surgeries and disease states. The relationship between intra-operative anesthesia management and the development of this syndrome has never been fully elucidated. OBJECTIVES: The primary objective of this study was to determine the relationship of multiple intra-operative factors on the pathogenesis of TTS. METHODS: A single-center retrospective review of all liver transplants performed at Mayo Clinic Florida from January 2005 to December 2014. Patients developing left ventricular dilation and a concomitant decrease in ejection fraction, a negative cardiac catheterization, or stress test within 30 days of transplantation were identified. Cases were matched 2:1 to controls with respect to MELD, age, sex, and indication for transplantation. Our evaluation included liver graft characteristics, intra-operative medications, and intra-operative hemodynamic measurements. RESULTS: We identified 24 cases of TTS from a pool of 1752 transplants, for an incidence of 1.4%. No statistically significant differences in intra-operative measures between the two groups were identified (all P ≥ .08). CONCLUSION: Our exploratory, single-center retrospective review evaluating 46 intra-operative characteristics found no association with the development of TTS.
