Atrial Fibrillation

Atrial fibrillation research centers on atrial structure, flow, and rhythm-related cardiovascular MRI questions, with connections to valve disease, cardiac function, and advanced flow analysis.

Overview

Atrial function and hemodynamic assessment are central to this application area.

Left-atrial flow analysis connects atrial fibrillation research with brain-risk and appendage-stasis questions.

Mitral-regurgitation flow analysis links the area to valve-facing cardiovascular MRI.
