Chapter e29
Video e29-1A

Real-time two-dimensional echocardiographic images of a patient with a normal heart. A. Parasternal long-axis view. There is symmetric contraction of the ventricles, evidenced by a decrease in cavity size and increase in wall thickness during systole. Echocardiographic imaging is performed in multiple acoustic windows with different transducer rotations so that the entire heart and great vessels can be displayed in various planes. Most information from a study is obtained from visual analysis of the two-dimensional images, although objective measurements of cardiac dimensions can be made.

Real-time two-dimensional echocardiographic images of a patient with a normal heart. B. Parasternal short-axis view. There is symmetric contraction of the ventricles, evidenced by a decrease in cavity size and increase in wall thickness during systole. Echocardiographic imaging is performed in multiple acoustic windows with different transducer rotations so that the entire heart and great vessels can be displayed in various planes. Most information from a study is obtained from visual analysis of the two-dimensional images, although objective measurements of cardiac dimensions can be made.

Video e29-2A

Real-time two-dimensional echocardiographic images of a patient with a severe decrease in left ventricular systolic function. The estimated ejection fraction is 20%. A. Parasternal long-axis view.

Video e29-3A

Real-time two-dimensional echocardiographic images of a patient with hypertrophic cardiomyopathy. There is a marked increase in left ventricular wall thickness with hyperdynamic systolic function. A. Parasternal long-axis view.

Video e29-4

Real-time two-dimensional parasternal long-axis images from a patient with aortic stenosis. There is normal left ventricular cavity size with normal systolic function. The aortic valve is thickened and calcified, with restricted opening.
