Transcript of the video: Closure line of aorticvalve on M-Mode echocardiogram, is seen as central line, while in bicuspidaorticvalve, it is an eccentric closure, nearer to one of the walls of the aorta. That is an important feature of bicuspidaorticvalve on M-Mode echocardiogram.
In this view, you can see that mitral leaflets are thickened. This is anterior mitral leaflet, thickened, and in the closed position of mitralvalve, when there should be no flow to the left atrium, you are seeing a jet, a mosaic jet, which has been traced out. This is the mitral regurgitation jet.
Here, this is the forward flow through the mitralvalve in diastole in red. This is reverse flow from the aorticvalve, that is aortic regurgitation jet. Area of the jet corresponding to the receiving chamber, that is left atrium, that is also deciding factor in assessing the severity of mitral regurgitation.

Transcript of video: Hypoplastic Left Heart Syndrome is a very severe form of congenital heart disease, in which, the left ventricle, aorta and mitral and aorticvalves are hypoplastic and valves may be atretic as well. It has a very poor survival. This is diagrammatic representation of hypoplastic left heart syndrome.
Mitralvalve leaflets seen in open position between the left ventricle and left atrium are thickened. The large aortic regurgitation jet can be seen as a mosaic jet in the left ventricular outflow tract anterior to the anterior mitral leaflet. Aorticvalve is seen as grossly thickened and calcified.
Right ventricular outflow tract, left ventricle, left atrium, aorta, aorticvalve, mitralvalve. Location of the transducer here, in the parasternal region. This is the parasternal long axis view. These are the things you have seen in that inset image. This is movement of the anterior wall of the right ventricle.
This is the aorticvalve in closed position and mitralvalve also appears to be closed in position. That is because timing of the image may be in such a way that, it could have been in such a way that both valves are in closed position. Separation between the attachments of the aortic and mitralvalve.
Tracing in the lower part is tissue Doppler imaging from the medial mitral annulus. Opening and closing movements of the aortic and mitralvalves are visible. Slight downward angulation of the transducer from this view gives the left ventricular cross section with mitralvalve cross section within.
