Figure 1 Apical 4-Chamber View Showing the Changes of Left Atrial Size After CRT
In a responder of left ventricular reverse remodeling, the LA size after atrial contraction was significantly reduced when compared between baseline (A) and 3-month follow-up (B), in contrast to a nonresponder in whom the LA size remained unchanged between baseline (C) and 3-month follow-up (D). CRT = cardiac resynchronization therapy.
