Abstract： Surgical repair of functional tricuspid regurgitation (FTR) is often carried out concomitantly with other leftsided heart valve procedures. Though diseases of both left heart valve and tricuspid were treated during the surgery, postoperative residual or recurrent tricuspid regurgitation has been clearly associated with progressive heart failure and worsened longterm survival. To date, surgical interventions mainly address FTR at three anatomic levels: commissure, annulus and leaflets. However, a certain mid and longterm failure rate after operation still exists. High surgical mortality rates have been reported in patients with recurrent tricuspid regurgitation requiring complex reoperations. With a better understanding of tricuspid anatomical complex and valvuloplasty, significant improvements have been made in FTR surgical indications and techniques. This review article will focus on the development of surgical indications in tricuspid valve repair, while the repair techniques and their impact on longterm clinical outcome will also be compared.
