Why the study?
Mitral valve surgeries create substrates for postoperative arrhythmias, but it is not well understood why these macro- and microreentrant circuits develop.
Is a transseptal approach during mitral valve surgery associated with specific postoperative atrial tachyarrhythmias?
Is a transseptal approach during mitral valve surgery associated with specific postoperative atrial tachyarrhythmias?
A transseptal approach during mitral valve surgery may create an arrhythmogenic substrate for right atrial roof tachycardias that is not clearly related to surgical scar.
No takes yet. Share an insight, caveat, or question.
Transseptal mitral valve surgery was associated with right atrial roof flutter; hypothesis-generating for arrhythmogenic substrate, needs prospective confirmation.
Gandhavadi et al. (2020) studied this question.
