Does 2D radial strain echocardiography predict early mitral regurgitation reduction in patients undergoing cardiac resynchronization therapy?
2D radial strain echocardiography can identify specific patterns of left ventricular mechanical dyssynchrony that predict early reduction in mitral regurgitation following cardiac resynchronization therapy.
Goland et al. (2009) conducted an observational in Mitral regurgitation in patients undergoing cardiac resynchronization therapy (n=32). Baseline 2D radial strain (2-DRS) echocardiography parameters was evaluated on Early mitral regurgitation (MR) reduction post-cardiac resynchronization therapy. Baseline time-to-peak delay on 2-DRS between inferior and anterior LV segments, preserved posterior wall strain, and MRJA/LAA <40% were associated with significant MR reduction post-CRT.
