sorry after reading the question again it doesn't make sense, so here it goes again keeping the followin statement in mind:
in RV pressure overload there is leftward ventricular septal shift and reversal of septal curvature present throughout the cardiac cycle with most marked distortion of the left ventricle at end-systole. In a patient with RV volume overload, the septal shift and flattening of VS curvature occurs predominantly in mid to late diastole with relative sparing of LV deformation at end-systole.
With this statement in mind, does this still apply in a post-op septal state?
Just a question ~ will the use of the cardiac cycle to see when the flattening occur still be useful/accurate in the presence of the abnormal/bouncy septal motion(Post AVR)?
YEA DRDAVEMD IT DOES SEEM THAT THE FLATTENING OCCURS IN SYSTOLIC PHASE OF CARDIAC CYCLE , VERY TYPICALFOR RV ISOLATED OVERPRESSURE WITHOUT CONCOMITANT RV VOLUME OVERLOAD
Hey Jorg when you say COMET TAIL ....You mean water in the interlobular septa of the wet lung or you talk about a real artifact ???? I do think that is quite common this sign of extravascular water in such patients....you talk about that??? Sorry for any interruption between you and the sender of this nice clip
I'm very sorry, I've done an orthographic mistake: I intended to write/ say "COMET-TAIL-ARTEFACT" not "COMMON-TAIL-ARTEFACT". I thank for having patience.
Thanks a lot for this impressive vid! I´m under the impression, that there is a systolic (perhaps caused by a PH; is a lung diesease known as underlying disease like COPD?) AND a diastolic (volume overload?) flattening of the IVS. I´ve noticed two artefacts: one artefact of the lung ventral to the left ventricle (seems like a common-tail-artefact, respectively a rocket-artefact of the lung) > any indications of lung oedema except that artefact? the other artefact flashes in the course of systole ventral to the left ventricle depicted as a bright stripe: It seems like an artefact of the lung, too, I couldn´t clearly distinguish, whether it is an artefact of the lung or of the pericardium. But I don´t think it is an artefact of the pericardium, because that would mean AIR in the pericardial sac.
In this parasternal short axis transthoracic clip, you can see the D shape of the LV common in patients with RV pressure overload. The IV septum also bounces in this particular patient with a history of sternotomy for aortic valve replacement.
