Figure 1

The preoperative echocardiogram was showing no obstruction of the left ventricular outflow tract. (a) The apical four-chamber view. (b) The apical four-chamber view with flow mapping. (c) The apical three-chamber view. (d) The apical three-chamber view with flow mapping. A normal left ventricular contraction and mild aortic regurgitation was noted on the apical three-chamber view (Supplement video 1).
