Figure 3

Transthoracic echocardiography showed an apical hypokinesia with normal left ventricular systolic function (a). Left ventricular outflow tract obstruction was confirmed by color flow acceleration with high-pressure gradient; maximal velocity () 3.2 m/s at resting and 5.0 m/s after Valsalva maneuver (b).
