Objectives To elucidate the impact of regulation of tricuspid regurgitation (TR) using tricuspid annuloplasty on postoperative changes in right ventricular (RV) systolic and diastolic functions. Methods We enrolled 69 patients who underwent aortic or mitral valve surgery between July 2016 to March 2018 without recurrence. Patients with concomitant coronary artery bypass grafting or a history of previous cardiovascular surgery were excluded, remaining 45 patients enrolled. Patients were divided into two groups according to concomitant tricuspid annuloplasty (T: n = 12 vs non‐T: n = 33). RV global longitudinal strain (RVGLS), RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and early tricuspid inflow velocity/early diastolic tricuspid annular velocity ratio (tricuspid E/e') were assessed as functional indices at preoperative, postoperative and 1‐year follow‐up periods. Results RVFAC deteriorated postoperatively but recovered at follow‐up in group T, whereas that in group non‐T showed gradual deterioration overtime. RVGLS and TAPSE showed similar temporary deterioration and recovery between groups. Tricuspid E in group T increased postoperatively and showed significant difference, which was kept until follow‐up period. Tricuspid e' decreased postoperatively, and recovered slightly in both groups. As a result, postoperative RV diastolic function (tricuspid E/e') showed significant difference between groups. This difference was maintained until follow‐up. Conclusions RV systolic function deteriorated postoperatively, but there was a tendency to improve at follow‐up regardless of tricuspid annuloplasty. RV diastolic function may potentially be impaired when TR was regulated by tricuspid annuloplasty.
