Figure 1 Tissue Doppler echocardiography spectral curve from a 21-year-old man with transposition of the great arteries after a Mustard operation. There is no detectable myocardial velocity during atrial contraction (A wave) related to the P wave on the electrocardiogram. The isovolumic myocardial acceleration is calculated as the difference between baseline and peak velocity (stars) during isovolumic contraction divided by their time interval.
