This is the region where the transducer is placed and the image looks inverted, because it is imaging from apex upwards. Left ventricle, right ventricle, left atrium and part of the aorta. That is why it is called as the five chamber view. This is the region of the right atrium. Here you can see an MR jet. That is, flow away from the transducer is depicted as blue. Flow towards the transducer is depicted as red. 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. In case of jets, you can compare the area of the jet and the receiving area. In case of AR, you can see the left ventricle and the AR jet and in MR, you can see the left atrium and the MR jet. The width of the jet at the beginning of the jet, is important in deciding on severity. 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. In case of AR, you can also see, how long into the left ventricle it is extending. If it is extending fully, that is more severe. Width, if it is more, that is higher regurgitant orifice and also more severe AR. Here also, the extent into the left atrium can be thought of as indicating severity of mitral regurgitation. These are the features, you have AR jet, and MR jet, in a still image of colour Doppler echocardiogram.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Transcript of the video: This is a still image from a colour Doppler echocardiogram, obtained from the apical five chamber view.
