Purpose : We evaluated the risk factor for progression of tricuspid regurgitation (TR) and suggested the optimal criteria of a tricuspid annuloplasty in patients with less than moderate functional TR.

Methods : From August 2007 to December 2014, 227 patients (56.4 ± 12.1 years old) with less than moderate TR underwent mitral valve surgery for rheumatic or degenerative mitral valve disease without tricuspid valve procedure. The preoperative TR was graded from 1 to 3; 1=trivial, 2=mild, and 3=mild to moderate. TV annulus diameters were measured in the transthoracic apical 4-chamber view in late diastole. The clinical follow-up durations was 57.5 ± 31.2months.

Results : Nine (3.9%) patients developed moderate or greater TR during follow-up (severe: 2 patients, moderate: 7 patients). TV annular size and preoperative atrial fibrillation were associated with development of TR ≥moderate in multivariable analysis (p = 0.007 and p = 0.010, respectively). TV annulus sizes of all patients who developed TR ≥ moderate were lower than 40mm of current recommendation. The TV annular size of 29.6mm was a cut-off value predicting the recurrent of TR ≥ moderate.

Conclusion : Although the follow-up duration was short, the progression of TR was not infrequent in patients with untreated less than moderate TR. TV annular size was a risk factor for development of TR ≥moderate and the optimal cut-off value for predicting TR ≥moderate was 26.9mm. Aggressive approach for TV annuloplasty would be helpful to prevent the progression of less than moderate FTR.
