European Registry Study on Lymphatic Interventions

This European multicenter observational study aims to evaluate the real-world use, timing, and outcomes of lymphatic interventions in patients with congenital heart disease and/or primary lymphatic disorders. The study will examine the effectiveness of diagnostic imaging and interventional techniques, such as lymphatic embolization, in improving clinical symptoms, biomarkers, and fluid-related complications. The central question is whether early diagnosis and targeted intervention can lead to clinically meaningful improvements and reduced need for reintervention. Data collected retrospectively and prospectively from participating centers will help identify predictors of outcome, assess disease severity, and inform standardized diagnostic and therapeutic pathways across Europe.
