Hi guys,

I am a consultant in Intensive Care Medicine working at King's College Hospital in London, UK.

During my post-graduate training I studied first focused and then comprehensive transthoracic echocardiography gaining the European Society of Cardiology's (ESC) TTE accreditation. Following completion of specialty training in ICM I took up a post-CCT fellowship in peri-operative and critical care echocardiography at the royal Brompton Hospital and gained the ESC's TOE accreditation.

I run numerous hands-on courses teaching TTE and TOE (from the most basic through to comprehensive scans).

Videos posted here are designed to support the in-course teaching, but are made available to all. Please feel free to share as widely as possible.

New Foundations of Echocardiography (FoE) courses are advertised here: twitter.com/EchoFoundations

I'm also one of the founders of the South London Intensive Care Echo group. For more resources check out www.criticalcareecho.com

    excuse me sir, i want to ask something about the AR jet, yes i understand the red is AR jet during diastole means that red towards the probe and also LV. so where does that blue color come from and go to ? cause during diastole, the only blood flow is LA to LV which in this case toward the probe and the color should be red why blue ?, i know blue is away from probe and correct me if i am wrong the probe position is in the upper left side side isnt ? (marked with that long straight line), please correct me, thank you

    Hi, thanks for the question, which highlights an important point. The convention to demonstrate flow towards the probe as red, and away from the probe as blue, only works for blood which is flowing at relatively low velocities. If we look at the clips in which the AR is demonstrated, the scale is set from +61.6cm/s to -61.6cm/s. When set like this, the software can correctly identify the direction of blood flow, as long as the apparent blood flow velocity is under 61.6cm/s. Once the apparent blood flow velocity exceeds this, the software cannot determine the direction that the blood is travelling, and incorrectly asigns the flow the wrong colour (we term this 'alaising'). We can't just turn up the scale, because Pulsed Wave (PW) Doppler, of which Colour Doppler is one form, has an inherent maximum speed limit. Blood velocity largely depends upon the pressure gradient between where the blood is coming from and where it is going to. Aortic regurgitation is leaving the aorta and going to the LV, in diastole. Let's imagine a situation whereby we have an aortic iastolic pressure of 72mmHg and an LV diastolic pressure of 8mmHg. This gradient, 64mmHg, would be expected to generate a blood velocity of ~400cm/s, far in excess of our scale. Indeed, as a general rule of thumb, most abnormal flow in the heart is high velocity, and so will almost always lead to alaising. 'Normal' flow in the heart tends to be much lower velocity, because a high gradient represents resistance to flow, and the normal heart is designed not to introduce unnecessary resistance. Even these 'normal' lower velocities frequently exceed the Colour Doppler scale, leading to alaising. I have a video which explains just why this happens, which you can see here: kzread.info/dash/bejne/m4iLzthrcsexoJs.htmlsi=4qgysUtcGGhP5_pi

    thanks for this great lecture. ı couldn't understand one thing for years, if cvp surrogate for RAP, why is not cvp increase with normal spontaneous inspiration ? logically if we suction more blood to righ atrium, right atrial pressure must be increase ? am i wrong? İt results in a bigger problem for me, is RAP just a back up pressure for venous return or in and on itself RAP a hemodynamically valuable parameter ? is İncreased RAP good thing (more preload) or bad thing (barrier for venous return) I cant understand this concept for years

    Hi P, thanks for the questions. Firstly, in a dynamic state, where the blood is always flowing, it helps to think that it is differences in pressure which cause the flow and hence the change in volume. So imagine that volume is dependent upon pressure. When intra-thoracic pressure drops during spontaneous inspiration, RA pressure also drops. It is the drop in pressure which entices more blood in to the RA. You can imagine that the negative pressure aorund the RA is pullig the walls of the RA apart, creating more space for additional volume. With respect to the question about is increased RAP good or bad, I think it is maybe helpful to distance ourselves from the terms of good and bad as absolute terms. We do know that in spontaneously ventilating patients, who have normal cardiac structure/function and are not acutely unwell, RAP is usually in the low single figures. This is where we expect RAP to be in health. In general a capable heart will try to keep venous return moving on, and therefore maintain a low RAP. There are of course exceptions. Some patients may develop a stiff right ventricle with restrictive physiology (a cohort in which I have seen this is adults with repaired tetralogy of Fallot). They have elevated RV end-diastolic pressure and therefore are reliant on an elevated RAP in order to fill the RV. In these patients a low RAP would be inappropriate. As is usually the case, assessments must be made in context, and consider all of the observations together, combined with what you know about this individual patient and their current condition (i.e. what - if any - acute pathology, will be effecting their physiology).

    Hi Michael, thanks for the encouragement. I had loads of plans for further lectures, and I had intended to cover the level 1 syllabus by the end of 2020. Unfortunately COVID... The pandemic is still pretty full on here in London and clinical work in ICU takes up most of my time. However I have been working on the valves lecture which is half way complete and will be up here at some point. Would be great to get the remainder of the first series of lectures online this year (2021), but global health emergencies may have other ideas.
