LTSI Consensus Guidelines: Preoperative Cardiac Evaluation in Adult Liver Transplant Recipients

Abstract

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality among LT candidates and accounts for up to 40% of the overall mortality within one month. It is influenced by traditional and nontraditional risk factors related to end-stage liver disease. A large proportion of CLD patients have underlying cardiovascular disease (CVD) especially if the etiology is metabolic associated steatohepatitis. Despite the large number of liver transplantations being conducted in India, there is a lack of an evidence-based guidelines for screening of CVD in this patient population. This consensus statement from Liver Transplant Society of India (LTSI) is the first attempt for developing an evidence-based document on preoperative cardiac evaluation from India. A task force consisting of transplant-anesthesiologists, transplant hepatologists, liver transplant surgeon and cardiologists from high volume centres was formed which reviewed the existing evidence and literature and formulated graded recommendations. The document focuses on identification of underlying cardiac pathologies, risk stratification and optimisation of modifiable cardiac diseases. Implementation of best practices and optimal strategies should be encouraged to improve cardiovascular outcomes in these populations.
