ABSTRACT
Background/Aims:
We sought to identify predictors of significant tricuspid regurgitation (TR) after successful permanent pacemaker (PPM) implantation in Korean patients.

Methods:
Of 404 patients who underwent PPM implantation, 187 patients who had both baseline and follow-up echocardiographic examinations were assigned to one of two groups: no development or change in TR (Group I, n = 172, 65.5 ± 13.7 years) versus the development of significant TR (Group II, n = 15, 72.1 ± 8.3 years). Clinical, laboratory, and echocardiographic variables were compared between the two groups.

Results:
Overall, the grade of TR was significantly aggravated from 0.46 ± 0.73 to 0.81 ± 0.84 (p < 0.001) during 3.1 ± 1.8 years of follow-up (0.49 ± 0.75 to 0.69 ± 0.74 in Group I, p < 0.001; 0.13 ± 0.35 to 2.27 ± 0.46 in Group II, p < 0.001). The de novo development or aggravation of TR was observed in 66 patients (35.3%), and significant TR developed in 15 patients (8.0%). The presence of atrial fibrillation (AF) was significantly higher (53.3 vs. 18.6%, p = 0.002), and the implantation of a ventricle pacing, ventricle sensing, inhibited by ventricular event (VVI) type pacemaker was more frequent in Group II than in Group I (46.7 vs. 15.1%, p = 0.002). Other variables were not different between the groups.

Conclusions:
The development or aggravation of TR was not rare after successful PPM implantation, even though the development of significant TR was uncommon. The presence of AF and the implantation of a VVI type pacemaker were predictors of the development of significant TR. Together, the results of this study suggest that the development or aggravation of TR should be monitored carefully after PPM implantation. (Korean J Med 2014;86:577-584)
