Abstract:
Objective To assess the morphological changes of tricuspid annulus in patients with functional tricuspid regurgitation(FTR)by real-time three-dimensional echocardiography.Methods Seventy-five FTR patients were divided into 4 groups according to the tricuspid regurgitation and transverse diameter of tricuspid annulus,which were group A(regurgitation more than moderate and dilated transverse diameter,n=21),group B(regurgitation less than moderate and dilated transverse diameter,n =18), group C(regurgitation more than moderate and normal transverse diameter,n = 1 9),group D (regurgitation less than moderate and normal transverse diameter,n =17).And 21 healthy controls were chosen to be group E.The 3D parameters including annular anterior-posterior diameter(AP),annular left-right diameter(SM),sphericity index(SI),non-planar angle(NPA),anterior annular length(Ant Ann), posterior annular length(Post Ann),annular circumference(Ann)and annular area(Area)were analyzed. Results SM,AP,Post Ann,Ann and Area of group A and B were larger than those in group E,whereas SI and Ant Ann only larger in group A(P<0.05).There were positive correlations between SM,AP,Post Ann,Ann,Area and the degree of regurgitation in group A(P <0.05).The patients of group C showed larger SM,Ant Ann,Post Ann,Ann and Area compared with patients in group E(P <0.05).There were no significant difference in all 3D parameters between group D and E(P >0.05).Conclusions FTR patients with regurgitation more than moderate or dilated transverse diameter are accompanied with changes of 3D annular parameters. The real-time three-dimensional echocardiography is helpful to judge morphological changes of tricuspid annulus in patients with FTR.
