Figure 1

Circumferential 2D strain before (A) and after (B) 4 years of CRT in a responder. Parasternal short axis view at the level of the papillary muscles. Before CRT, there is asynchronous circumferential contraction with postsystolic shortening and passive movement of the inferior and posterior segments, which are scar tissue. After 4 years of CRT, there is increased synchronous contraction, a reduction of postsystolic shortening; the scarred segments (inferior and posterior) show no circumferential contraction.
