Overview
The hypothesis is that renal function will improve following tricuspid valve intervention. A reduction in renal biomarkers is also expected. Furthermore, based on previous assessments, it is anticipated that there will be an improvement in volume status (reduced edema), symptom burden, and physical capacity in patients. Additionally, the study will assess the impact of the intervention on functional parameters such as motor capacity, physical activity, performance of activities of daily living, and ultimately, participation and quality of life.
