Implication
RA vortex mapping in health is feasible with 4D-flow MRI; leaves open clinical or pathologic relevance.
Structured PICO
Can 4D-flow MRI quantitatively characterize right atrial flow patterns and vortex formation in healthy subjects?
P
Population
12 healthy subjects
I
Intervention
4D-flow magnetic resonance imaging (MRI) at 3T
O
Outcome
Flow patterns and energy transfer within the right atrium (RA), specifically vortex formationsurrogate
4D-flow MRI can quantitatively characterize right atrial flow dynamics, demonstrating that blood flow momentum is preserved during systole within a dominant vortex.
