Abstract

Cardiac resynchronization therapy (CRT) can improve cardiac function in patients with heart failure and left bundle branch block. To test a new synchrony index derived from mitral annular velocity by color tissue Doppler, 19 subjects were studied: 9 patients with heart failure and left bundle branch block at baseline and at 1, 3 and 6 months after CRT and 10 normal controls. The synchrony index in patients with heart failure was less than that in controls at baseline (r = 0.60 ± 0.13 vs 0.94 ± 0.02; p <0.01), but improved at 6 months after CRT (r = 0.77 ± 0.09; p <0.05 vs baseline).
