Key result
Transseptal surgical access for mitral valve surgery did not significantly affect the incidence of postoperative atrial fibrillation or atrioventricular block compared to left atrial access.
Why the study?
Does transseptal surgical access compared to left atrial access affect the incidence of postoperative atrial fibrillation and atrioventricular block in patients undergoing mitral valve surgery?
Cohort (n=103)
No
Does transseptal surgical access compared to left atrial access affect the incidence of postoperative atrial fibrillation and atrioventricular block in patients undergoing mitral valve surgery?
Absolute Event Rate: 23.1% vs 27.3%
p-value: p=>0.05
The choice of surgical access (transseptal vs. left atrial) for mitral valve surgery does not significantly affect the incidence of postoperative atrial fibrillation or atrioventricular block.
Transseptal access was not associated with higher postoperative AF or block rates; leaves open optimal approach selection in mitral surgery.

Toporcer et al. (2017) conducted a cohort in Mitral valve disease requiring surgery (n=103). Transseptal surgical access vs. Left atrial surgical access was evaluated on Postoperative atrial fibrillation (p=>0.05). Transseptal surgical access for mitral valve surgery did not significantly affect the incidence of postoperative atrial fibrillation or atrioventricular block compared to left atrial access.
