case_images: Transthoracic echocardiography showed a hyperdynamic left ventricle with markedly increased left ventricular wall thicknesses and asymmetrical septal hypertrophy (Fig. 1).
case_images: Left ventricular apical five-chamber view of showing that a dynamic left ventricular outflow tract obstruction was present, with a resting maximal instantaneous gradient of 55 mmHg (B: peak velocity, 3.7 m/s). With the Valsalva maneuver, the gradient increased to 114 mmHg (C: peak velocity, 5.3 m/s).
