Abstract:
We performed cardiac resynchronization therapy (CRT) in addition to aortic valve replacement (AVR) in a 74-year-old patient with poor cardiac function (New York Heart Association functional class III, ejection fraction 15%), complete right bundle branch block (CRBBB), left posterior hemiblock (LPH), and aortic valve insufficiency. Tissue Doppler echocardiography showed synchronicity of the septum and posterior segments in the left ventricle, and that contraction of the septum was in the systolic phase of the cardiac cycle after CRT. The New York Heart Association functional class improved from III to I after the operation. CRT of the dyssynchronized myocardium in a patient with CRBBB and LPH can improve regional cardiac function and synchronicity.
