ObjectiveSignificant tricuspid regurgitation (TR) recurs after tricuspid valve repair of functional TR in 15% to 20% within the first year, and 30% to 70% within 5 years. Prior investigations report leaflet tethering, and not tricuspid valve annular diameter (TVAD), as predictive of recurrent TR. The authors hypothesize that pre-repair TVAD is predictive of repair failure for functional TR.ParticipantsFifty-four patients with functional TR scheduled for left heart surgery and tricuspid valve repair with ring annuloplasty.DesignRetrospective study design. Pre- and post-repair transthoracic and intraoperative transesophageal echocardiographic data included left and right ventricular functions, tricuspid leaflet tethering height, TVAD, and TR severity. Successful repair was defined as ≤2+ TR.SettingTertiary care medical center.InterventionsNone.MeasurementsForty-five patients had a successful repair and 9 did not. Preoperative and intraoperative TVAD in diastole (TVADdiast) ≥4.2 cm, and preoperative systole (TVADsyst) ≥3.7 cm, but not leaflet tethering, were predictive of repair failure. Right ventricular (RV) width >4.88 cm was associated with repair failure. Neither pre- nor post-repair pulmonary artery systolic pressures (PASP) were predictors of repair failure. However, PASP did not change nor did RV function improve in the nonsuccessful repair group.ConclusionFor patients with functional TR undergoing primary left heart surgery, preoperative TVAD (systole and diastole), RV width, and postoperative RV function were predictors of repair outcome. Earlier TV repair and optimizing right heart function may improve repair outcome.Copyright © 2019 Elsevier Inc. All rights reserved.
