  • A Randomized Controlled Trial of Concomitant Tricuspid Annuloplasty for Patients Underwent Mitral Valve Replacement: UCG Evaluation 2 Years After Surgery

    Objective To evaluate the right ventricular function of the patients 2 years after surgery by ultrasonic cardiography (UCG) who underwent mitral valve replacement (MVR) concomitant tricuspid annuloplasty (TAP). Method We finally identified 36 patients required MVR with tricuspid valve annular dilation concomitant merely mild tricuspid regurgitaion (TR) based on preoperative UCG in our hospital between April and November 2012 year. All patients were randomly divided into two groups by digital table including a tricuspid annuloplasty group (a TAP group, n=18, 7 males and 11 females at age of 45.67±12.49 years) and a no-tricuspid annuloplasty group (a NTAP group, n=18, 6 males and 12 females at age of 45.44±10.48 years). General clinical data and extracorporeal circulation data were recorded. UCG evaluation was practiced preoperation, alone with 1 week, 6 months, and 2 years after surgery. Results Two years postoperative maximal long-axis of RA (RAmla), mid-RA minor distance (RAmmd), right ventricle dimension-1(RVD1) , right ventricular fractional area change (RVFAC), 3D RV end-systolic volume (3DRVESV), tricuspid valve annular end-diastolic dimension (TVAEDD), tricuspid valve annular end-systolic dimension (TVAESD) of patients were all smaller in the TAP group than those in the NTAP group. Yet right ventricular ejection fraction (RVEF), percent shorting of tricuspid valve annulus (PSTVA) were greater in the TAP group than those in the NTAP group, although there was no statistical difference between the two groups in two years postoperative 3D RV end-diastolic volume (3DRVEDV). The patients in the TAP group had a superior trend than that of the NTAP group. Moreover, the patients' TR constituent ratio in the TAP group was much better than that of the NTAP group in 2 year after operation. Conclusions Concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent MVR is favorable for the recovery of their 2 years postoperative function of tricuspid valve and right ventricle. It is benefit to reduce patient's long term postoperative TR residues and exacerbation.
