Key result
Cross-clamp time >60 min (OR 4.1; 95% CI 1.3-12.9) and concomitant mitral valve surgery (OR 3.8; 95% CI 1.2-12.2) independently predicted permanent pacemaker placement after tricuspid valve surgery.
Why the study?
What are the perioperative predictors of permanent pacemaker placement and long-term dependence following tricuspid valve surgery?
Population
237 patients undergoing tricuspid valve surgery from 2008 to 2014, mean age 66 ± 15 years, 29% male.

Cross-clamp time >60 minutes and concomitant mitral valve surgery are independent predictors of the need for permanent pacemaker implantation after tricuspid valve surgery.
Mar et al. (2016) conducted an observational in Tricuspid valve disease requiring surgery (n=237). Cross-clamp time >60 min vs. Cross-clamp time ≤60 min was evaluated on Permanent pacemaker placement (PPM) (OR 4.1, 95% CI 1.3-12.9, p=0.015). Cross-clamp time >60 min (OR 4.1; 95% CI 1.3-12.9) and concomitant mitral valve surgery (OR 3.8; 95% CI 1.2-12.2) independently predicted permanent pacemaker placement after tricuspid valve surgery.
