Cirrhotic Cardiomyopathy and Cardiac Failure after Liver Transplantation: A Case Series.

Preoperative cardiac functional assessment has been a long-debated topic in liver transplantation. Debate continues to exist regarding the use of invasive cardiac studies, and the utility of each prior to transplant. Despite the debate, a 7% mortality can be attributed to significant cardiac events. We present a case series of 3 patients who underwent orthotopic liver transplantation and developed significant cardiac dysfunction postoperatively. All preoperative cardiac assessments in each patient were normal with no hemodynamically significant abnormalities. Interestingly enough, each patient developed cardiac failure due to completely different diagnoses.

Utilization of Intraoperative TEE to Assess Supraventricular Tachycardia-Inducing Right-Sided Cardiac Compression by the Liver, Post-Liver-Transplantation Status.

This unique and interesting case report involves a patient who recently underwent a combined liver and kidney transplant (due to autosomal dominant polycystic kidney disease) and subsequently suffered from episodes of supraventricular tachycardia (SVT) secondary to the new liver graft compressing the right atrium and ventricle. After this was diagnosed, the patient underwent operative plication of the right hemidiaphragm. Intraoperative transesophageal echocardiography was used to demonstrate cardiac compression from the liver and demonstrate resolution of compression after plication of the hemidiaphragm.

Adherence to guidelines for the management of local anesthetic systemic toxicity is improved by an electronic decision support tool and designated "Reader".

BACKGROUND AND OBJECTIVES: A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated "Reader" role on team performance during an in situ simulation of LAST. METHODS: Participants were randomized to Reader + DST (n = 16, rDST) and Control (n = 15, memory alone). The rDST group received the assistance of a dedicated Reader on the response team who was equipped with an electronic DST. The primary outcome measure was adherence to guidelines. RESULTS: For overall and critical percent correct scores, the rDST group scored higher than Control (99.3% vs 72.2%, P < 0.0001; 99.5% vs 70%, P < 0.0001, respectively). In the LAST scenario, 0 (0%) of 15 in the control group performed 100% of critical management steps, whereas 15 (93.8%) of 16 in the rDST group did so (P < 0.0001). CONCLUSIONS: In a prospective, randomized single-blinded study, a designated Reader with an electronic DST improved adherence to guidelines in the management of an in situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena.
