Objective Aims of this study were to evaluate if tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular peak systolic velocity (TAPSV) indicators could accurately reflect the postoperative right ventricular systolic function in patients after mitral valve or aotic valve surgery combined with tricuspid annuloplasty ring.Methods 45 patients were studied, who underwent left heart valve surgery combined with tricuspid annuloplasty ring.Transthoracic echocardiography were performed pre-surgery and1week, 3, 6, and 12 months post-surgery.In addition to routine preoperative and postoperative transthoracic echocardiography parameters,also measured RVAC, TAPSE,TAPSV.Comparatively analysised preoperative and postoperative indicators .Results TAPSE preoperative 20.25±3.05 mm, postoperative (8.68±2.83)mm, (9.13±3.12) mm, (9.20±2.46) mm, (9.29±2.58) mm at1week, 3, 6, and 12 months respectively and TAPSV preoperative (17.8±4) crn/s,postoperative(11.93±2.32) cm/s, (12.12±2.06) cm/s, (12.85±3.11) crn/s, (12.86±3.13) cm/s at1week, 3, 6, and 12 months respectively).Postoperative values were significantly (P < 0.01) lower after surgery in comparison with pre-surgical values.On the contrary, pre-operative RVAC (45.62±4.32%) did not change significantly after surgery(46.21±3.89)%, (48.45±4.02) %, (47.33±3.86) %, (47.92±4.33) % at each step.Conclusion Right ventricular function evaluation indicators TAPSE and TAPSV underestimates right ventricular systolic function after after mitral valve or aotic valve surgery combined with tricuspid annuloplasty ring.So, TAPSE and TAPSV were not recommended to evaluate fight ventricular systolic function after after tricuspid annuloplasty.
