PURPOSE: We examined changes of TR (tricuspid regurgitation) after mitral valve repair for degenerative mitral regurgitation (MR) and investigated their contributing parameters.
METHODS: We divided 205 patients undergoing mitral valve repair for degenerative MR into 3 groups: up-grade (n = 65), down-grade (n = 29), and no-change (n = 111) of TR during postoperative follow-up. Preoperative, immediate postoperative, and mid-term postoperative parameters included MR grade, right ventricular (RV) pressure, RV Tei index, left ventricular Tei index, and presence of atrial fibrillation.
RESULTS: Preoperative incidence of atrial fibrillation in the down-grade group was lower (7%) than those in the other groups (37% and 34%). In the immediate postoperative stage, the TR grade of the up-grade group was significantly lower (p <0.001) and RV Tei index of the downgrade group was significantly lower (p = 0.049). In mid-term postoperative stage, the TR grade (p <0.001) and RV Tei index (p = 0.034) of the down-grade group were significantly lower, and the MR up-grade in the TR up-grade group was significantly frequent (p = 0.008).
CONCLUSIONS: TR became deteriorated even after the operation in about 30% and remained unchanged in about 50%. The RV Tei index can be a reliable parameter to predict postoperative improvement of TR. The postoperative MR up-grade was related to the TR up-grade.
