Abstract:
Objective To evaluate the function of tricuspid annulus using omni-directional M-mode echocardioraphy(OME) in patients during mitral valve replacement(MVR) ,and provide a reference for clinical decision about concomitant tricuspid annuloplasty for patients under MVR . Methods Twenty-five normal subjects were selected as control group . Thirty-three patients under MVR for mitral stenosis were divided into tricuspid annuloplasty group( TVP group , n =17) and non-tricuspid annuloplasty group( NTVP group , n =16) .Transesophageal echocardiography ( TEE) was performed before and after surgery . The right ventricular fractional area change( RVFAC) ,maximal tricuspid annular diameter( TADmax) ,tricuspid annular fractional shortening( TAFS) and tricuspid regurgitation( TR) degree were detected by 2D and color Doppler echocardiography . OME and quantitative tissue velocity imaging(QTVI) were used to measure the peak systolic velocity of tricuspid annular ,which were defined as Sm and St . Results In the TVP group , TADmax decreased and TR degree improved significantly compared with preoperative date ( P< 0 .05) . Preoperative Sm had nagative correlation with TADmax/BSA ( r = -0 .53 , P <0 .01) and RVFAC( r =0 .87 , P < 0 .01) ,and positive correlation with TAFS ( r = 0 .68 , P < 0 .01) . Conclusions The peak systolic velocity of tricuspid annulus measured by OME can assess the function of tricuspid annulus additionally ,and provide a reference for clinical decision about concomitant tricuspid annuloplasty for patients under MVR .
