Left Atrial and Appendage Hemodynamics

Cardiovascular MRI and flow quantification characterize left-atrial and left-atrial-appendage function across atrial fibrillation, silent brain infarction, and population-linked flow studies.

Overview

Left-atrial and appendage hemodynamics connect atrial fibrillation, stasis, population risk, and silent brain infarction.

Left-atrial and appendage flow connects to atrial fibrillation, stasis, and brain-related risk markers.

Atrial-fibrillation, valve-flow, and hemodynamic measurement converge in this area.
