Interest in Tricuspid valve disease grew exponentially in the last years in response to an increased awareness of the poor outcome of patients with functional Tricuspid Regurgitation (TR). Earlier reports advocated for a more conservative TR management in patients undergoing left-sided heart valve surgery but more recent guidelines advised for a more aggressive TR management, as accumulating evidence demonstrates its adverse impact on long term morbidity and mortality. Several papers have been published analyzing the results of surgical tricuspid valve repair but the length of the follow-up is usually limited to 10 to 12 years. With this study the investigators aim to analyze the very long-term results (>15years) of tricuspid valve repair according to the surgical method employed for valve repair (suture vs ring annuloplasty).

Inclusion Criteria:

• cardiac surgery treatment of TR, isolated or in conjunction with other procedures on the left heart
• patients operated on between January 1998 and December 2004

Exclusion Criteria:

- patients operated for non-valvular procedures (e.g. coronary artery bypass)
