Perioperative predictors of permanent pacing and long-term dependence following tricuspid valve surgery: a multicentre analysis.
Aims: Permanent pacemaker placement (PPM) is often required after valvular surgery and is especially common following tricuspid valve surgery [tricuspid valve repair or replacement (TVR)]. Literature suggests that surgical intervention for isolated tricuspid valve disease is becoming more prevalent. Predictors of PPM dependency following TVR are currently unknown and would be clinically useful from a prognostication standpoint.
Methods and results: We conducted a multicentre, retrospective study to assess perioperative factors of TVR that predispose to PPM placement and long-term PPM dependency from 2008 to 2014. Regression analysis was used to determine independent predictors of PPM implantation. A total of 237 patients (age 66 ± 15 years, 29% male) were studied, and the incidence of PPM placement following TVR was 27% (65/237). No significant differences were observed between those who received PPM and those who did not in age (P = 0.092), gender (P = 0.359), and co-morbidities. Regression analysis identified cross-clamp time >60 min (OR 4.1, 95% CI 1.3-12.9, P = 0.015) and concomitant mitral valve surgery (OR 3.8, 95% CI 1.2-12.2, P = 0.026) as independent risk factors for PPM following TVR. Long-term PPM dependency data were only available in 28 patients who received PPM with 14 of these patients developing long-term dependence. The only statistically significant difference noted was an increased frequency of coronary artery disease in the long-term dependent group vs. the non-dependent group (64% vs. 14%, P = 0.018).
Conclusion: Cross-clamp time >60 min and concomitant mitral valve surgery were independent predictors of PPM implantation following TVR. Long-term PPM dependency is more prevalent after TVR than other types of valvular surgery.
