TDI Is a Better Choice than M-Mode and 2D Echocardiography

Echocardiographic Assessment of Myocardial Asynchrony

“…Some limitations including abnormal septal motion secondary to pulmonary hypertension or volume overload were eliminated by exclusion criteria. Our conclusions concern patients with preserved left ventricular ejection fraction and only minimal impairment of left ventricular segments motion and, as far as we can tell, are not affected by the limitations raised by Sun et al [1] .…”

“…We would like to thank Sun et al [1] for the interest in our paper [2] and for the comments regarding the possible use of tissue Doppler imaging (TDI) in the assessment of myocardial asynchrony.…”
