Left atrial (LA) strain is an important marker of left atrial remodeling. Two-dimensional atrial strain has been studied using echocardiography and MRI cine. Here we develop a 3D strain method, using volumetric cine data sets at multiple phases. The volumes were registered and 3D strain maps were generated, demonstrating patterns of regional strain in the LA.
