Abstract Funding Acknowledgements Type of funding sources: None. Background Percutaneous tricuspid valve edge-to-edge repair (pTVR) is a promising interventional technique for patients with regurgitation (TR), but guidance regarding patient selection and echocardiographic screening lacking. The aim this study was to identify measurements which may predict pTVR success. Methods Before after pTVR, data, including 3D full-volume datasets, were obtained quantified. Right ventricular assessments included ejection fraction (RVEF3D) diastolic (RVVd3D) systolic (RVVs3D) volumes. Also evaluated were: right atrial (RA) volume, effective regurgitant orifice area by PISA method (EROAPISA), vena contracta (VCA3D) multiplanar reconstruction from colour Doppler loop (Figure 1a), maximal annulus zoom image 1b), tenting area. TR severity graded according EROAPISA VCA3D as grade 1+ 5+. Results Patients (n= 44, age 72 ± 9 years, 20 male) at least moderate severe undergoing consecutively included. divided into groups their post-pTVR grade. Group 1 had ≤2+, group 2 ≥3+.Echocardiographic parameters before both are presented in Table 1. As expected, TVR ≥3+ significantly worse pre-intervention severity, dimensions, chamber ROC curves the prediction ≤2+ (mild moderate) (defined <0.75 cm² <0.4 cm²) drawn different features 2). yielded highest under curve followed TV anatomy (Annulus area3D, Tenting area) volume. Conclusion A thorough evaluation dimensions echocardiography, particulary Doppler, aids probability Figure.

Edge-to-edge repair of tricuspid valve in a corrected transposition of the great vessels.
We describe the case of a 27-year-old Caucasian woman with corrected transposition of the great vessels, who presented with cardiac failure. She had severe regurgitation of the systemic tricuspid valve with a huge annulus that was not suitable for annuloplasty. She underwent a successful repair using the Alfieri edge-to-edge technique and was asymptomatic 15 months after surgery. Such a repair ...
متن کاملEndovascular Edge-to-Edge Mitral Valve Repair
Background—The edge-to-edge technique is an accepted method for the surgical repair of a regurgitant mitral valve. This study reports the initial use of an endovascular technology that enables a double-orifice edge-to-edge mitral valve repair without cardiopulmonary bypass in an animal model. Methods and Results—Adult pigs (n 14) were anesthetized, and left thoracotomy was performed for epicard...
متن کاملTricuspid valve tethering predicts residual tricuspid regurgitation after tricuspid annuloplasty.
BACKGROUND Tricuspid valve (TV) annuloplasty is recommended for functional tricuspid regurgitation (TR), which is caused by TV annulus dilatation and tethering of the leaflets. However, the impact of TV deformations on the outcome of TV annuloplasty remains unknown. The goal of this study was to investigate the relationship between preoperative TV deformation and residual TR after TV annuloplas...
متن کاملEdge-to-edge mitral valve repair without ring annuloplasty for acute ischemic mitral regurgitation.
BACKGROUND Alfieri edge-to-edge mitral repair has been used clinically with ring annuloplasty to correct ischemic mitral regurgitation (IMR), but its efficacy without concomitant ring annuloplasty has not been described in this setting. METHODS Seventeen sheep underwent implantation of 9 radiopaque markers on the left ventricle, 8 on the mitral annulus (MA), 1 on each papillary muscle (PM) ti...
