Diastolic dysfunction on echocardiography does not predict survival after transjugular intrahepatic portosystemic stent-shunt in patients with cirrhosis.

BACKGROUND: Cardiac dysfunction is frequently observed in patients with cirrhosis. There remains a paucity of data from routine clinical practice regarding the role of echocardiography in the pre-assessment of transjugular intrahepatic portosystemic stent-shunt.

AIM: Our study aimed to investigate if echocardiography parameters predict outcomes after transjugular intrahepatic portosystemic stent-shunt insertion in cirrhosis.

METHODS: Patients who underwent echocardiography and transjugular intrahepatic portosystemic stent-shunt insertion at the liver unit (Birmingham, UK) between 1999 and 2016 were included. All echocardiography measures (including left ventricle ejection fraction; early maximal ventricular filling/late filling velocity ratio, diastolic dysfunction as per British Society of Echocardiography guidelines) were independently reviewed by a cardiologist. Predictors of 30-day and overall transplant free-survival were assessed.

RESULTS: One Hundred and Seventeen patients with cirrhosis (median age 56 years; 54% alcohol; Child-Pugh B/C 71/14.5%; Model For End-Stage Liver Disease 12) underwent transjugular intrahepatic portosystemic stent-shunt for ascites (n = 78) and variceal haemorrhage (n = 39). Thirty-day and overall transplant-free survival was 90% (n = 105) and 31% (n = 36), respectively, over a median 663 (IQR 385-2368) days follow-up. Model for End-Stage Liver Disease (P < 0.001) and Child-Pugh Score (P = 0.002) significantly predicted 30-day and overall transplant-free survival. Model for End-Stage Liver Disease ≥15 implied three-fold risk of death. Six per cent (n = 7) of patients pre-transjugular intrahepatic portosystemic stent-shunt had a history of ischaemic heart disease and 34% (n = 40) had 1 or more cardiovascular disease risk factors. Fifty per cent (n = 59) had an abnormal echocardiogram and 33% (n = 39) had grade 1-3 diastolic dysfunction. On univariate analysis none of the echocardiography measures pre-intervention were related to 30-day or overall transplant-free survival post-transjugular intrahepatic portosystemic stent-shunt.

CONCLUSIONS: Ventricular, in particular diastolic dysfunction in patients with cirrhosis does not predict survival after transjugular intrahepatic portosystemic stent-shunt insertion. Model for End-Stage Liver Disease and Child-Pugh scores remain the best predictors of survival. Further prospective study is required to clarify the role of routine echocardiography prior to transjugular intrahepatic portosystemic stent-shunt insertion.
