Table 4 Sensitivity and specificity of TAC and TACI for evaluation of significant tricuspid annulus dilatation

From: Risk factors for postoperative recurrent tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery and the association between tricuspid annular circumference and secondary tricuspid regurgitation

Variables Cut off point Sensitivity % Specificity % AUC P value
TAC 11.45 cm 82.9 95.0 0.915 < 0.001
TACI 7.07 cm/m2 75.0 85.0 0.825 < 0.001
  1. TAC tricuspid annular circumference, TACI tricuspid annular circumference/body surface area
