Start Date

Study Type

INTERVENTIONAL

Conditions

MASLD TIPS Liver Cirrhosis, Alcoholic Cirrhosis of Liver Heart Decompensation

Summary

The aim of this clinical trial is to investigate the development of cardiac decompensation following transjugular intrahepatic portosystemic shunt (TIPSS) implantation in order to draw conclusions for future treatment methods or exclusion criteria prior to TIPS implantation. The main questions to be answered are: How often do symptoms of cardiac decompensation develop over a one year period? What laboratory, clinical or imaging morphological changes are associated with this? In addition to the standardised clinical procedure for TIPSS implantation, participants will undergo 3 cardiac magnetic resonance imaging (MRI), extended echocardiographic examinations (both just before, 3 days after and 3 months after implantation) and laboratory chemistry tests for specific endothelial and inflammatory markers (just before, on the day of implantation, 1 day after, 1, 3, 6 and 12 months after implantation).

Plain Language Summary

Simplified for easier understanding

This study is measuring how a procedure called TIPSS (transjugular intrahepatic portosystemic shunt) — a tube placed inside the liver to relieve pressure from advanced liver disease — affects heart function. Using both MRI and echocardiography (heart ultrasound), researchers are comparing the two imaging methods to see which one better captures changes in the heart after this procedure. **You may be eligible if...** - You are between 18 and 99 years old - You have decompensated liver cirrhosis (advanced liver disease with complications) - You are scheduled to receive an elective TIPSS procedure at the participating hospital **You may NOT be eligible if...** - You are pregnant - You have metal implants or other reasons you cannot have an MRI - You have claustrophobia or cannot lie still for the MRI - You are in a critical or unstable medical condition Talk to your doctor to see if this trial is right for you.

Interventions

DIAGNOSTIC_TESTCardiac MRI

Additional to standard clinical practice Patients will receive a cardiac magnetic resonance imaging without contrast. Measured parameters are enddoastolic and endsystolic volume (in ml oder ml/body surface area (BSA)), stroke volume (in ml) of right and left ventricle absolute and relatvie to body surface area (BSA), ejection fraction in % of right and left ventricle, myocardial Strain in % of right and left ventricle if applicable. T1 and T2 relaxation times are obtained and aortic and pulmonary artery flow parameters are measured.

DIAGNOSTIC_TESTBlood samples

We will take additional blood samples for the analysis of markers of bacterial translocation (e.g. LBP, EndoCAb, 16S rRNA), detection of bacterial markers (bacterial extracellular vesicles), inflammatory markers (e.g. IL-1ß, TNF-α, TGF-ß, IL-6, CXCL8, IL1-RA, IL-10, IL-18) and monocyte/macrophage activation markers (sCD14, sCD163, sCD87, sCD206), bile acids (including TCA, GCA, GCDCA, TCDCA, TLCA, GLCA, TDCA, GDCA, CA, CDCA, UDCA, DCA, TUDCA, LCA), lipids and lipoproteins (triglyerides, cholesterol, LDL/HDL cholesterol), coagulation factors (e.g. VWF, ADAMTS13, fibrinogen), markers of cardiac remodeling (e.g. NT-proBNP; troponin, VEGF-D, cleaved Gasdermin D, HMGB1) and Immunophenotyping of monocytes/macrophages, T and B cells (e.g. CD14, CD16, MERTK, CD4, CD127, CD25, TREM1/2).

DIAGNOSTIC_TESTEchocardiography

Patients will receive an extended echocardiographic protocol. In addition to standard clinical parameters, we will collect study specific parameters such as LV EF in %, global longitudinal strain in %, septal e' velocity (cm/s), E/e' ratio, left atrial volume index (LAVI) (in ml/m2), tricuspid regurgitation velocities (m/s).
