M-Mode Echocardiogram in Left Ventricular Dysfunction

All About Cardiovascular System and Disorders

Transcript of the video: This is a still image from a colour Doppler echocardiogram, obtained from the apical five chamber view. Here, this is the forward flow through the mitral valve in diastole in red. This is reverse flow from the aortic valve, that is aortic regurgitation jet. That also occurs in diastole.

M-Mode Echocardiogram in LV Dysfunction

All About Cardiovascular System and Disorders

Transcript of the video: This is a still image of M-Mode Echocardiogram. Right ventricular outflow tract, left ventricle, left atrium, aorta, aortic valve, mitral valve. M-Mode is Time-Motion Mode. The horizontal axis is time. Vertical axis is distance from the transducer. This is the parasternal long axis view.

Echocardiogram in Rheumatic Mitral and Aortic Regurgitation

All About Cardiovascular System and Disorders

You can see the reverse flow into the left ventricle from the aorta, with the aortic valve in closed position. Beacuse, as the aortic valve is closed, and the regurgitant jet is coming in, and left ventricular diastolic pressures are lower than the aortic pressures. Here it is the AR jet.

Eccentricity Index in Bicuspid Aortic Valve

All About Cardiovascular System and Disorders

Transcript of the video: Closure line of aortic valve on M-Mode echocardiogram, is seen as central line, while in bicuspid aortic valve, it is an eccentric closure, nearer to one of the walls of the aorta. That is an important feature of bicuspid aortic valve on M-Mode echocardiogram.

Similarly, for echocardiogram, what we would do usually is, first we do a clinical history evaluation, then physical examination, and after that only we proceed with echocardiography in our routine work. You can see the two dimensional sector imaging from an echocardiogram and I have marked out the aorta.

Echocardiographic evaluation in aortic regurgitation

All About Cardiovascular System and Disorders

Echocardiogram in parasternal long axis view shows dilated left ventricle, left atrium, aorta and a small portion of the right ventricle, which is usually the outflow region. Mitral valve leaflets seen in open position between the left ventricle and left atrium are thickened. Aortic valve is seen as grossly thickened and calcified.
