Novel application of 3D contrast-enhanced CMR to define fibrotic structure of the human sinoatrial node in vivo

Abstract

This is the first study to visualize the 3D human SAN fibrotic structure in vivo using LGE-CMR. Identification of the 3D SAN location and its high fibrotic content by LGE-CMR may provide a new tool to avoid or target SAN structure during ablation.
