Ninety-one adult patients underwent three different methods of annuloplasty and compared them by the amount of tricuspid regurgitation. Group Ⅰ (n=17) is Kay method, Group Ⅱ (n=46) is modified Kay method and Group Ⅲ (n=28) is De Vega and
modified De
Vega method.
Preoperative and postopeative size of the liver and its function, the cardiothoracic ratio, EKG and echocardiogram were analyzed. The follow up was done for all the patients (mean 20.0*8.5 months). The postoperative size of the liver, the
postoperative
cardiothoracic ratio and the postoperative systolic pressure of the right ventricle decreased significantly compared to preoperative size, ratio and pressure (p=0.0001, p=0.0001, p=0.0001). But there was no differences between the groups.
The results of annuloplasty revealed that tricuspid regurgitation improved postoperatively (p=0.0001) even though there was no statistically significant differences in relation to the methods of annuloplasty.
The right ventricular systolic pressure and the amount of regurgitation decreased significantly during the postoperative period by performing 3 different methods of annuloplasty, although we could not find the differences between the three
different
methods.
