Cardiovascular magnetic resonance reveals stable myocardial tissue characteristics despite cardiac remodelling after transjugular intrahepatic portosystemic shunt in liver cirrhosis
- prospective
- multiparametric cardiovascular magnetic resonance (CMR)
Authors' conclusion
TIPS implantation induces progressive biventricular dilatation, increased stroke volume, and eccentric remodelling. Despite these marked structural adaptations, myocardial tissue characteristics remained largely unchanged during short- and mid-term follow-up, suggesting predominantly preload-driven cardiac remodelling.
