Key result
The superior transseptal approach for mitral valve surgery did not significantly increase the rate of permanent pacemaker implantation (10.6% vs 4.5%, p=0.436) or mortality compared to conventional left atriotomy.
Why the study?
Does the superior transseptal approach improve clinical outcomes or affect atrial vulnerability compared to conventional left atriotomy in patients undergoing mitral valve surgery?

Absolute Event Rate: 10.6% vs 4.5%
p-value: p=0.436
The superior transseptal approach for mitral valve surgery is safe and does not lead to serious adverse effects on sinus node function compared to conventional left atriotomy.
No takes yet. Share an insight, caveat, or question.
Supports safe use of superior transseptal approach in mitral valve surgery; extends RCT evidence on atriotomy techniques without excess pacemaker risk.
Aydın et al. (2014) conducted an RCT in Mitral valve surgery (n=91). Superior transseptal approach vs. Conventional left atriotomy was evaluated on Permanent pacemaker implantation (p=0.436). The superior transseptal approach for mitral valve surgery did not significantly increase the rate of permanent pacemaker implantation (10.6% vs 4.5%, p=0.436) or mortality compared to conventional left atriotomy.
