Why the study?
To compare the outcomes of the classic biatrial cut-and-sew maze procedure versus its left atrial variant in patients with atrial fibrillation and concomitant cardiac pathology.
Does the classic biatrial maze procedure compared to the left atrial variant improve sinus rhythm maintenance or reduce complications in patients with atrial fibrillation undergoing concomitant cardiac surgery?
Does the classic biatrial maze procedure compared to the left atrial variant improve sinus rhythm maintenance or reduce complications in patients with atrial fibrillation undergoing concomitant cardiac surgery?
The left atrial maze procedure offers comparable efficacy to the biatrial approach for maintaining sinus rhythm at 12 months, but with a significantly lower risk of postoperative sinus node dysfunction.
