Effect of electronic device implantation on tricuspid valve function
Abstract：Objective To study the effect of electronic device implantation on tricuspid valve regur‐gitation and its mechanism .Methods Four hundred and twenty patients who underwent perma‐nent pacemaker and defibrillator implantation were divided into normal tricuspid valve function group (n=316)and abnormal tricuspid valve function group (n=104) .Their clinical and echocar‐diographic data were compared and analyzed by Spearman correlation analysis .Results The re‐gurgitation area/right atrium area (TR/RA) was significantly higher in tricuspid valve regurgita‐tion patients after operation than before operation (P<0 .01) ,in patients who underwent single or double‐channel pacemaker implantation than in those who underwent CRTP implantation (P<0.01) ,in normal tricuspid valve function group after operation than before operation (P<0 .05 , P<0 .01) ,and in 13 -24 ,25 -36 and≥37 months than in 0 -12 months after operation ( P<0.05 ,P<0 .01) .Spearman correlation analysis showed that the postoperative tricuspid valve re‐gurgitation was positively related with the preoperative tricuspid valve regurgitation ,implanted pacemaker time ,right atrium diameter ,and NT‐proBNP (r= 0 .405 ,P= 0 .005;r= 0 .246 ,P=0.005;r=0 .144 ,P=0 .043 ;r=0 .153 ,P=0 .028) .Conclusion Electronic device implantation can cause different degrees of TR regardless of preoperative tricuspid valve regurgitation .
