Hepatorenal dysfunction assessment with the Model for End-Stage Liver Disease Excluding INR score predicts worse survival after heart transplant in pediatric Fontan patients

BackgroundFontan physiology results in multiorgan dysfunction, most notably affecting the liver and kidney. We evaluated the utility of Model for End-Stage Liver Disease Excluding INR (MELD-XI) score, a score evaluating the function of both liver and kidney to identify Fontan patients at increased risk for morbidity and mortality post–heart transplant. MethodsThe Pediatric Heart Transplant Society database was queried to identify Fontan patients listed for heart transplant between January 2005 and December 2018. MELD-XI scores were calculated at listing and heart transplant. A multivariable analysis was conducted to identify risk factors for post–heart transplant mortality. Demographic, clinical characteristics, and survival differences were evaluated and compared between the high and low MELD-XI score cohorts. The impact of changing MELD-XI scores during the waitlist period on post–heart transplant outcomes was also evaluated. ResultsOf 565 Fontan patients who underwent transplantation, 524 (93%) had calculable MELD-XI scores at the time of heart transplant: 421 calculable at listing and 392 calculable at listing and at heart transplant. On multivariable analysis, only MELD-XI score (squared) (hazard ratio, 1.007), history of protein-losing enteropathy (hazard ratio, 2.1), and ventricular assist device use at transplant (hazard ratio, 3.4) were risk factors for early phase post–heart transplant mortality. Patients with high MELD-XI scores at heart transplant had inferior survival post–heart transplant (P = .02); those in the high MELD-XI score cohort at wait listing and heart transplant tend to have the worst post–heart transplant survival; however, this was not significant (P = .42). ConclusionsThe MELD-XI, an easily calculated score, serves as a valuable aid in identifying pediatric Fontan patients at increased risk for post–heart transplant mortality.

Abstract 12917: Prognostic Value of the Combination of Model for End-stage Liver Disease Excluding Inr Score and Non-alcoholic Fatty Liver Disease Fibrosis Score in Patients Admitted for Acute Heart Failure

Background: Cardiohepatic interactions have been a focus of attention in heart failure(HF), and the model for end-stage liver disease excluding INR (MELD-XI) has been shown to be useful for prediction of poor outcome in patients (pts) with acute decompensated heart failure (ADHF). Furthermore, it has been reported that liver stiffness predicts adverse prognosis in pts with HF. Liver fibrosis is assessed by non-invasive fibrosis markers such as Fibrosis-4 (FIB4) index, non-alcoholic fatty liver disease fibrosis score (NFS) and aminotransferase to platelet ratio index (APRI). Recently, a new group of HF pts with mid-range ejection fraction (HFmrEF) has been defined, separated from reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). However, there is little information available on the comparison of prognostic significance of MELD-XI and liver fibrosis scores in ADHF pts, relating to LVEF. Methods: We prospectively studied 466 consecutive ADHF pts (HFrEF (LVEF≦40%): n=164, HFmrEF (40<LVEF<50): n=104 and HFpEF (LVEF≧50%): n=198). At the discharge, we calculated MELD-XI, FIB4 index , NFS, and APRI. The endpoint was all cause death (ACD). Results: During a follow-up period of 2.8±1.5 years, 143 pts had ACD. At multivariate Cox analysis, MELD-XI and FIB4 index was independently associated with ACD irrespective of LVEF. The pts with both greater MELD-XI ([HFrEF]≥25.8, [HFmrEF]≥33.2, [HFpEF]≥30.1) and greater FIB4 index ([HFrEF]≥2.58, [HFmrEF]≥2.58, [HFpEF]≥2.22) had a significantly increased risk of ACD than those with either and none of them in all three groups. Conclusions: The combination of MELD-XI and FIB4 index might be useful for stratifying pts at risk for ACD in ADHF pts with irrespective of LVEF.

Prognostic value of the model for end-stage liver disease excluding INR score (MELD-XI) in patients with adult congenital heart disease.

Patients with adult congenital heart disease (ACHD) are at increased risk of developing late cardiovascular complication. However, little is known about the predictive factors for long-term outcome. The Model for End-Stage Liver Disease eXcluding INR (MELD-XI) score was originally developed to assess cirrhotic patients and has the prognostic value for heart failure (HF) patients. In the present study, we examined whether the score also has the prognostic value in this population. We retrospectively examined 637 ACHD patients (mean age 31.0 years) who visited our Tohoku University hospital from 1995 to 2015. MELD-XI score was calculated as follows; 11.76 x ln(serum creatinine) + 5.11 x ln(serum total bilirubin) + 9.44. We compared the long-term outcomes between the high (≥10.4) and the low (<10.4) score groups. The cutoff value of MELD-XI score was determined based on the survival classification and regression tree (CART) analysis. The major adverse cardiac event (MACE) was defined as a composite of cardiac death, HF hospitalization, and lethal ventricular arrhythmias. During a mean follow-up period of 8.6 years (interquartile range 4.4–11.4 years), MACE was noted in 51 patients, including HF hospitalization in 37, cardiac death in 8, and lethal ventricular arrhythmias in 6. In Kaplan-Meier analysis, the high score group had significantly worse MACE-free survival compared with the low score group (log-rank, P<0.001). Multivariable Cox regression analysis showed that the MELD-XI score remained a significant predictor of MACE (hazard ratio 1.36, confidence interval 1.17–1.58, P<0.001) even after adjusting for patient characteristics, such as sex, functional status, estimated glomerular filtration rate, and cardiac function. Furthermore, CART analysis revealed that the MELD-XI score was the most important variable for predicting MACE. These results demonstrate that the MELD-XI score can effectively predict MACE in ACHD patients, indicating that ACHD patients with high MELD-XI score need to be closely followed.

Calculation of the ALMA Risk of Right Ventricular Failure After Left Ventricular Assist Device Implantation.

Right ventricular failure after continuous-flow left ventricular assist device (LVAD) implantation is still an unsolved issue and remains a life-threatening event for patients. We undertook this study to determine predictors of the patients who are candidates for isolated LVAD therapy as opposed to biventricular support (BVAD). We reviewed demographic, echocardiographic, hemodynamic, and laboratory variables for 258 patients who underwent both isolated LVAD implantation and unplanned BVAD because of early right ventricular failure after LVAD insertion, between 2006 and 2017 (LVAD = 170 and BVAD = 88). The final study patients were randomly divided into derivation (79.8%, n = 206) and validation (20.1%, n = 52) cohorts. Fifty-seven preoperative risk factors were compared between patients who were successfully managed with an LVAD and those who required a BVAD. Nineteen variables demonstrated statistical significance on univariable analysis. Multivariable logistic regression analysis identified destination therapy (odds ratio [OR] 2.0 [1.7-3.9], p = 0.003), a pulmonary artery pulsatility index <2 (OR 3.3 [1.7-6.1], p = 0.001), a right ventricle/left ventricle end-diastolic diameter ratio >0.75 (OR 2.7 [1.5-5.5], p = 0.001), an right ventricle stroke work index <300 mm Hg/ml/m (OR 4.3 [2.5-7.3], p < 0.001), and a United Network for Organ Sharing modified Model for End-Stage Liver Disease Excluding INR score >17 (OR 3.5 [1.9-6.9], p < 0.001) as the major predictors of the need for BVAD. Using these data, we propose a simple risk calculator to determine the suitability of patients for isolated LVAD support in the era of continuous-flow mechanical circulatory support devices.

Prognostic utility of MELD-XI in adult congenital heart disease patients undergoing cardiac transplantation.

Model of End-Stage Liver Disease eXcluding INR (MELD-XI) at cardiac transplant has demonstrated prognostic survival utility, but has not been specifically validated in adult congenital heart disease (ACHD) in a registry study. Adults undergoing first-time orthotopic heart transplant from 2005 to 2015 in the United Network for Organ Sharing (UNOS) registry were examined in parallel: ACHD (n=543), ischemic-dilated cardiomyopathy (IDCM, n=6954) and valvular heart disease (VHD, n=355). Our primary endpoint was a composite of death, graft failure, and retransplantation assessed at 3months (early), and those with freedom from early endpoint were reassessed at 5years (late). Interactions between hepatorenal indices and waitlist time were examined. Secondary outcomes relating to long-term morbidity were assessed at late endpoint. Freedom from endpoint analysis in ACHD at clinically relevant endpoints was also conducted. Model of End-Stage Liver Disease eXcluding INR score at transplant associated with an increased risk of early endpoint in all cohorts. At late endpoint, bilirubin level associated with increased risk uniquely in ACHD. Model of End-Stage Liver Disease eXcluding INR holds prognostic application to ACHD in early time points and demonstrates unique waitlist interactions. Transplant bilirubin level may hold significance in long-term risk stratification of the ACHD population. Time on waitlist is an important consideration to contextualize these values.
