M-mode Echocardiography: Fluttering of the Anterior Mitral Valve Leaflet

This series contains images of the classic M-mode finding of fluttering of the anterior leaflet of the mitral valve and its etiologies.

Aortic Regurgitation and Fluttering of the Anterior Mitral Valve Leaflet on M-mode Echocardiography

by: Joe B. Calkins, Jr. M.D.

M-mode recording through the mitral valve from the parasternal long axis position demonstrating diastolic fluttering of the anterior mitral valve leaflet in a patient with aortic regurgitation.

Parasternal long axis echocardiographic image showing mild aortic regurgitation by color flow imaging. The regurgitant jet strikes the anterior mitral valve leaflet during diastole, resulting in fluttering of this leaflet as shown in the previous image.

Atrial Fibrillation and Fluttering of the Anterior Mitral Valve Leaflet on M-mode Echocardiography

by: Joe Calkins, M.D.

M-mode recording through the mitral valve from the parasternal long axis position demonstrating diastolic fluttering of the anterior and mitral valve leaflets in a patient with atrial fibrillation. Also note the irregular intervals between diastolic opening of the mitral valve and the variable length of diastole resulting from the irregular rhythm.

Atrial Fibrillation and Fluttering of the Anterior Mitral Valve Leaflet on M-mode Echocardiography

by: Joe Calkins, M.D.

ECG showing atrial fibrillation with a ventricular rate of approximately 75/min. This rhythm results in fluttering of anterior and posterior mitral valve leaflets, variable intervals between diastolic opening of the mitral valve and variable length of diastole as shown in the previous image.
