Echocardiography

On-X Valve Echo Presentation

Echocardiography Aortic View

The still-frame views shown in the echocardiography are examples of typical On-X appearances.

Apical two-chamber view of aortic regurgitant jets.

Continuous wave doppler spectral envelope.

Direction of View

Aortic_dir2

As shown, the regurgitant pivot purging jets in the On-X heart valve flow outward toward the wall of the ventricle or atrium. When viewed parallel to the valve pivot axis, the jets diverge. When viewed perpendicular to the valve pivot axis, the jets converge. This is unlike the inward directed regurgitant jets of other bileaflet valves that appear to converge in all views.

Echocardiography Mitral View

The still-frame views shown in the echocardiography are examples of typical On-X appearances.
