Abstract

Abstract: Introduction: Transcatheter tricuspid annuloplasty is a promising therapeutic alternative for the treatment of tricuspid regurgitation (TR) in patients with a high surgical risk. To date, the published experience with percutaneous tricuspid devices is quite limited. The objective of this study is to present the impact of the transcatheter tricuspid annuloplasty with band implantation on the degree of TR and on several echocardiographic parameters in a series of 27 patients. Methods: A single-center cohort of 27 patients was followed up prospectively after the transcatheter tricuspid annuloplasty with band implantation (mean follow-up: 10, 39 months) (Figure 1). The degree of tricuspid regurgitation (mild, moderate, severe, massive, torrential) was measured before and after the procedure, as well as at 6 months and one year of follow-up. Other parameters have also been considered, such as the septal-lateral end-diastolic diameter of the tricuspid annulus, the vena contracta (VC), regurgitant orifice area (ROA) 2D, tricuspid annular plane systolic excursion (TAPSE), right ventricular ejection fraction (RVEF) and fractional area change (FAC). Results: Initially, there were 22.3% of patients with torrential TR, 29.6% massive and 48% severe. After the procedure, these percentages were reduced to 3.8%, 7.7% and 23.1% respectively, leading to an amount of 65% of patients with mild or moderate TR. With respect to the the diameter of the lateral septum ring, the mean was initially 44.74 mm. After the procedure, it decreased to 34.5 mm (22% of reduction) and, as can be seen during follow-up, it remains stable over time. The ROA and VC were also significantly reduced while TAPSE, CAF and RVEF do not show significant changes (Figure 2). Percutaneous tricuspid annuloplasty demonstrated a notable impact on the degree of tricuspid regurgitation reduction in the patients in our study. The differences are already noticeable from the moment of the procedure and are maintained throughout the follow-up, where the stability of the diameter of the septolateral ring, the ERO and the vena contracta is observed.
