Long-term Clinical and Hemodynamic Outcomes of Edge-to-Edge Repair for Tricuspid Regurgitation

The edge-to-edge technique (Alfieri stitch) has been widely adopted in mitral valve but not tricuspid valve (TV) repair. We evaluated long-term clinical and hemodynamic outcomes of tricuspid edge-to-edge repair. We retrospectively reviewed 237 patients (mean age, 58.4 ± 13.9 years) who had undergone tricuspid edge-to-edge repair from January 2001 to March 2019 in our institution. Tricuspid annuloplasty was performed in 175 patients (73.8%) using ring (91 [38.4%]) or suture (84 [35.4%]) annuloplasty. Concomitant procedures were mitral valve replacement (133 [56.1%]), mitral valve repair (52 [21.9%]), aortic valve replacement (41 [17.3%]), and maze operation (138 [58.2%]). Postoperative echocardiography revealed mild or less tricuspid regurgitation (TR) in 220 patients (92.8%). Early mortality (
