Résumé

The 3-dimensional (3D) nature of sinoatrial node (SAN) function has not been characterized in the intact human heart. The purpose of this study was to characterize the 3D nature of SAN function in patients with structural heart disease (SHD) using simultaneous endocardial-epicardial (endo-epi) phase mapping. Simultaneous intraoperative endo-epi SAN mapping was performed during sinus rhythm at baseline (SR Sixteen patients with SHD were included. SR During mapping of the intact human heart, SAN demonstrated redundancy of sinoatrial exits with postoverdrive shift in sites of earliest activation and epi-endo dissociation of sinoatrial exits.

BACKGROUND
The 3-dimensional (3D) nature of sinoatrial node (SAN) function has not been characterized in the intact human heart.
OBJECTIVE
The purpose of this study was to characterize the 3D nature of SAN function in patients with structural heart disease (SHD) using simultaneous endocardial-epicardial (endo-epi) phase mapping.
METHODS
Simultaneous intraoperative endo-epi SAN mapping was performed during sinus rhythm at baseline (SR
RESULTS
Sixteen patients with SHD were included. SR
CONCLUSION
During mapping of the intact human heart, SAN demonstrated redundancy of sinoatrial exits with postoverdrive shift in sites of earliest activation and epi-endo dissociation of sinoatrial exits.
