Key result
Atrial 4-dimensional flow MRI revealed significantly increased global left atrial stasis in patients with persistent AF (52%) and AF in sinus rhythm (41%) compared to age-appropriate controls (29%).
Why the study?
Does left atrial 4-dimensional flow MRI detect differences in LA flow dynamics between patients with atrial fibrillation and healthy controls?
Cross-Sectional (n=111)
Does left atrial 4-dimensional flow MRI detect differences in LA flow dynamics between patients with atrial fibrillation and healthy controls?
4D flow MRI can detect significant changes in global and regional left atrial flow dynamics, such as increased stasis and reduced velocity, in patients with atrial fibrillation.

Supports 4D flow MRI for LA stasis assessment in AF; leaves open its prognostic or therapeutic role.
Markl et al. (2015) conducted a cross-sectional in Atrial fibrillation (n=111). Left atrial 4-dimensional flow magnetic resonance imaging vs. Healthy volunteers and age-appropriate controls was evaluated on Global LA stasis and peak velocity. Atrial 4-dimensional flow MRI revealed significantly increased global left atrial stasis in patients with persistent AF (52%) and AF in sinus rhythm (41%) compared to age-appropriate controls (29%).
