摘要

The authors recognize the limitations of our study, most of which are due to being a single-center study and the small sample size of our cohort. We tried to keep our population as homogeneous as possible and included patients only with cirrhosis. Imaging modalities like cardiac MRI, 3D echocardiography, and tissue Doppler imaging as well as exercise testing often give us significantly more information about cardiac function but come with their inherent limitations of requiring general anesthesia, limited availability, and age-dependent variability. We agree with both reviewers that our study lacks the longitudinal aspect which would allow us to study the reversibility of findings post-liver transplantation. However, the purpose of our study was to correlate the pre-transplantation echocardiographic findings as a risk stratification method for post-transplantation clinical measures like duration of mechanical ventilation and length of hospital stay. We believe that the results of our study can serve as a basis for further prospective studies in the evaluation of patients prior to liver transplantation as well as demonstrating reversal of findings in long-term post-transplant period.
