Abstract
Introduction
Tricuspid regurgitation (TR) is frequently associated with severe venous congestion, increasingly recognized as a key factor in the development of cardiorenal syndrome. While transcatheter tricuspid valve intervention (TTVI) has shown to be effective in TR reduction, their impact on visceral venous congestion remains unknown. The aim of our study was to investigate visceral venous congestion in patients with severe TR undergoing TTVI.
Methods
We prospectively enrolled 30 patients undergoing TTVI for severe TR. Renal venous blood flow was assessed by Doppler ultrasound examination at baseline and 1 to 3 months after the procedure. A 5-grade rating scale was developed to categorize venous flow from continuous (Grade I°) through discontinuous to a pendulous venous flow (Grade V°) within the kidneys.
