May support VVI for detecting longitudinal dysfunction in Takotsubo; hypothesis-generating and requires validation before clinical adoption.

Does velocity vector imaging (VVI) detect longitudinal systolic and diastolic dysfunction in patients with Takotsubo cardiomyopathy?
p-value: p=< 0.05
Vector velocity imaging demonstrates that Takotsubo cardiomyopathy involves both systolic and diastolic longitudinal dysfunction, beyond traditional radial dysfunction.
Burri et al. (2008) conducted an observational in Takotsubo cardiomyopathy (n=5). Velocity vector imaging (VVI) vs. Admission (baseline) was evaluated on Peak segmental longitudinal strain (S), velocity (V), and strain rate (SR) in systole and diastole (p=< 0.05). Velocity vector imaging demonstrated significant improvement in systolic strain, velocity, strain rate, and diastolic strain rate in involved left ventricular segments at follow-up (P<0.05).
