Why the study?
Patients with paroxysmal atrial fibrillation may have occult left ventricular disease, and this study aimed to identify LV hemodynamic inefficiencies in PAF patients with normal systolic function using 4-D flow CMR.
Does 4-D flow cardiac MRI identify left ventricular hemodynamic inefficiencies in patients with paroxysmal atrial fibrillation compared to healthy controls?
Does 4-D flow cardiac MRI identify left ventricular hemodynamic inefficiencies in patients with paroxysmal atrial fibrillation compared to healthy controls?
4-D flow cardiac MRI reveals occult left ventricular hemodynamic inefficiencies, specifically reduced direct flow and elevated delayed ejection, in patients with paroxysmal atrial fibrillation despite normal systolic function.

May detect occult LV impairment in PAF; hypothesis-generating and requires prospective validation before clinical use.
