Key result
Vector flow mapping demonstrates that systolic base-to-apex and basal intraventricular pressure differences are significantly reduced in patients with paroxysmal atrial fibrillation.
Why the study?
Does vector flow mapping evaluate left intraventricular pressure difference in patients with paroxysmal atrial fibrillation?
Does vector flow mapping evaluate left intraventricular pressure difference in patients with paroxysmal atrial fibrillation?
Vector flow mapping provides a visually quantitative method for evaluating left ventricular hemodynamic mechanics, demonstrating reduced systolic and basal intraventricular pressure differences in patients with paroxysmal atrial fibrillation.
Reduced pressure gradients may signal early LV impairment in paroxysmal AF; leaves open whether vector flow mapping aids risk stratification.
