Liver transplantation is a complex procedure performed on critically ill patients with multiple comorbidities, which requires the anesthesiologist to be facile with complex hemodynamics and physiology, vascular access procedures, and advanced monitoring. Over the past decade, there has been a continuing debate whether or not liver transplant anesthesia is a general or specialist practice. Yet, as significant data have come out in support of dedicated liver transplant anesthesia teams, there is not a guarantee of liver transplant exposure in domestic residencies. In addition, there are no standards for what competencies are required for an individual seeking fellowship training in liver transplant anesthesia. Using the Accreditation Council for Graduate Medical Education guidelines for residency training as a model, the Society for the Advancement of Transplant Anesthesia Fellowship Committee in conjunction with the Liver Transplant Anesthesia Fellowship Task Force has developed the first proposed standardized core competencies and milestones for fellowship training in liver transplant anesthesiology.

AbstractImprovements in early survival after liver transplant (LT) have allowed for the selection of LT candidates with multiple comorbidities. Cardiovascular disease is a major contributor to post‐LT complications. We performed a literature search to identify the causes of cardiac disease in the LT population and to describe techniques for diagnosis and perioperative management. As no definite guidelines for preoperative assessment (except for pulmonary heart disease) are currently available, we recommend an algorithm for preoperative cardiac work‐up.

AbstractIntroductionTakotsubo 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.ObjectivesThe primary objective of this study was to determine the relationship of multiple intra‐operative factors on the pathogenesis of TTS.MethodsA 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.ResultsWe 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).ConclusionOur exploratory, single‐center retrospective review evaluating 46 intra‐operative characteristics found no association with the development of TTS.

Intracardiac thrombosis (ICT) during orthotopic liver transplantation (OLT) is an uncommon event. However, it is a devastating complication with high mortality when it occurs. This study aimed to identify possible predisposing factors for ICT during OLT. We retrospectively identified the cases of all patients with ICT during OLT at our institution from 1998 to 2014. Of 2750 OLTs performed, 10 patients had ICT intraoperatively. The patients' immediate prethrombosis intraoperative hemodynamic and coagulation values and thromboelastography (TEG) data were reviewed. Preexisting venous thrombosis, atrial fibrillation, and the prior placement of a transjugular intrahepatic portosystemic shunt for portal hypertension were noted in several patients and may be related to ICT during OLT. A high Model of End‐Stage Liver Disease score, low cardiac output, and sepsis did not appear to be associated with ICT. ICT occurred in some patients without the administration of antifibrinolytic agents. TEG and coagulation parameters did not appear to be helpful in predicting the onset of ICT. Four patients had ICT in both right‐ and left‐sided heart chambers; none of these 4 patients survived. All 6 patients with only right‐sided thrombus survived. In those who survived, improved hemodynamics and clot disappearance on transesophageal echocardiography (TEE) occurred over time, even without the use of thrombolytics. Whether this is because of endogenous thrombolysis or distal clot propagation into the pulmonary vasculature, or both, is unclear. Tissue plasminogen activator may have a role in the resuscitation procedure. In conclusion, without the routine use of TEE during OLT, the incidence of ICT will remain an under‐recognized event.
