Key result
Permanent pacemaker implantation following aortic and mitral valve replacements was associated with a significantly higher risk of postoperative elevated tricuspid regurgitation (>2+) (OR 4.033) and increased late mortality.
Why the study?
Risk factors for permanent pacemaker implantation following mitral and aortic valve replacements with or without tricuspid annuloplasty needed to be identified.

Permanent pacemaker implantation following combined aortic and mitral valve replacement is associated with increased late mortality and worsened postoperative tricuspid regurgitation.
Aksoy et al. (2022) conducted a cohort in Aortic and mitral valve replacements (n=179). Permanent pacemaker implantation (PPI) vs. No permanent pacemaker implantation was evaluated on Postoperative elevated tricuspid regurgitation (>2+) (OR 4.033, 95% CI 1.321-12.308, p=0.014). Permanent pacemaker implantation following aortic and mitral valve replacements was associated with a significantly higher risk of postoperative elevated tricuspid regurgitation (>2+) (OR 4.033) and increased late mortality.
