Figure 3 Assessment of Atrial Strain at Mid Level of Left Atria in the Same Patients as in Figure 2

In a responder of left ventricular reverse remodeling, left atrial strain at ventricular end-systole (s), early diastole (e) as well as after atrial contraction (a) was increased when compared with baseline (A) and 3 months after cardiac resynchronization therapy (B). On the other hand, the nonresponder showed no improvement of atrial strain between baseline (C) and 3-month follow-up (D).
