Intrcardiac echo (ICE) helps in diagnosis of implantable device related endocarditis
Detection of vegetations on prosthetic material within the heart is often difficult as these structures may cause acoustic shadowing and reverberation artifacts. Even though trans esophageal echocardiography (TEE) [..]
Right to left shunt across subaortic VSD – echocardiogram
Blue colour in colour flow mapping (Color Doppler) echocardiography indicates flow away from the transducer. In this case it is flow from the right ventricle to the left [..]
Large subaortic VSD with aortic override – echocardioagram
Large subaortic VSD with aortic override – echocardioagram, seen from the parasternal long axis view. VSD: ventricular septal defect; IVS: interventricular septum; LV: left ventricle; AML: anterior mitral [..]
Trivial aortic regurgitation – echocardiogram
Trivial aortic regurgitation – echocardiogram seen on colour Doppler echocardiogram in the left image (AR). The bluish mosaic jet is seen into the left ventricular outflow tract just [..]
Device closing AP window – echocardiogram
Echocardiogram in parasternal short axis view showing a device closing aortopulmonary window (AP window). The circular shadow to the right of the device is the cross section of [..]
Yu index of longitudinal tissue Doppler dyssynchrony
Yu index of longitudinal tissue Doppler dyssynchrony is the standard deviation of time to peak systolic velocities from the onset of the QRS complex. This is calculated after determining [..]
Ventricular septal defect (VSD)
Swiss cheese ventricular septal defects Multiple muscular ventricular septal defects (VSD) are also called ‘swiss cheese’ VSD. Swiss cheese VSDs are difficult to close surgically. It is difficult [..]
Echocardiographic profile of prosthetic mitral valve
Evaluation of prosthetic valves is one of the difficult tasks in echocardiography because of the dense shadows caused by prosthetic valves. It may be virtually impossible to detect [..]
How can you make a TR get more prominent during Doppler echo?
A tricuspid regurgitation (TR) jet can be enhanced by deep inspiration or passive leg raising which increases the right sided inflow. Another method is to give agitated saline [..]
Diastolic function assessment by echo in the AF
Conventionally left ventricular diastolic function assessment by echocardiography relies on mitral inflow velocity measurement with demonstration of E/A reversal as an evidence of diastolic dysfunction. In atrial fibrillation, [..]
