Movement of the inter-atrial septum: everything has meaning
The inter-atrial septum (IAS) is a thin wall between the right and left atria. Normally, its motion (i.e., whether it sways towards the left or right atrium) is influenced by […]
Mass in the right atrium: an uninvited guest from the abdomen
These interesting images were shared by Dr. Ryan Henneberry, EM POCUS director at Dalhousie University. A 47-year-old gentleman presented with shortness of breath and a focused cardiac ultrasound revealed a […]
The RV inflow view
It is not always possible to obtain a good apical window to look for tricuspid regurgitation, which is one parameter that we commonly look at in nephrology patients with volume […]
Peri-aortic lymphoma seen on echocardiogram
Below are more echo images, mostly atypical views obtained from 4th – 5th intercostal space.
Pulmonary veins on cardiac ultrasound
In a recent twitter poll showing this parasternal long axis (PLAX) image, only 36% (N = 301) were able to identify the pulmonary vein. Even though the purpose of POCUS […]
Strange things around the IVC
A medical student is looking for inferior vena cava in a nephrology clinic patient and finds something ‘weird’ adjacent to the IVC. He/she calls the nephrology fellow for help. Here […]
Pitfalls of inferior vena cava M-mode
Visual estimation of IVC collapse on B-mode (grey scale image) is generally preferred to M-mode, though in theory, M-mode measurement might be able to give accurate collapsibility index. There are […]
IVC collapse: fact or artifact?
In clinical practice, size, and collapsibility of the IVC is used as a surrogate for right atrial pressure (RAP). In spontaneously breathing patients, inspiration causes negative intrathoracic pressure and collapses […]
What is LV foreshortening?
This is a commonly heard term in echocardiography. Foreshortening occurs when the ultrasound beam does not cut through the true apex of the left ventricle but transects above and anterior […]
