The study will examine the lymphatic functional and morphological status in patients with moderate tricuspid valve regurgitation compared to healthy age and gender-matched controls.~Subjects will be examined at one occasion using t2-weighted MRIs to evaluated lymphatic anatomy and Near-infrared fluorescence imaging for evaluation of superficial peripheral lymphatic function. Finally, the capillary filtration rate will be estimated using plethysmography.
