Abstract
Tricuspid regurgitation secondary to left heart disease is the most common etiology of tricuspid valve (TV) insufficiency. Therefore, the majority of the patients, who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe tricuspid regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. For patients requiring mitral valve surgery, tricuspid valve annuloplasty should be considered even in the absence of significant regurgitation, when severe annular dilatation is present. Secondary or functional TV insufficiency is primarily treated with valve reconstruction which carries a lower perioperative risk than valve replacement. Tricuspid valve repair with ring annuloplasty is associated with improved survival and a lower reoperation rate than with suture annuloplasty. Patients, who require tricuspid valve surgery either as an isolated or a combined procedure, still constitute a high-risk group. The long-term survival is poor.
