Echocardiographic evaluation in patient candidate for liver transplant: from pathophysiology to hemodynamic optimization

Abstract

Abstract Cardiovascular complications are common in patients with severe liver disease and are an important cause of peri-operative and post-transplant morbidity and mortality. Cirrhotic cardiomyopathy (CCM), often found in advanced liver disease, is characterized by diastolic dysfunction, systolic dysfunction, and electrophysiological abnormalities. While CCM may not cause symptoms at rest, it can become evident during stressful activities, such as surgery. Liver transplantation, while being the definitive treatment for end-stage liver disease (ESLD), carries significant cardiovascular risks. Preoperative cardiac evaluation is essential for assessing these risks and planning appropriate management. Cardiac imaging, particularly echocardiography, plays a crucial role in evaluating liver transplant candidates, helping to identify conditions such as CCM, pulmonary hypertension, hepatopulmonary syndrome, and others. Currently, liver transplant anesthetists must acquire echocardiographic knowledge and skills to evaluate the cardiocirculatory conditions of the transplanted patient, especially in the pre-operative phase, but also intra-operatively and post-operatively.
