Valvuloarterial impedance (Zva): Global left ventricular afterload in aortic stenosis Valvuloarterial impedance (Zva) is an echocardiographic measure of global left ventricular afterload in aortic stenosis [1]. It accounts
Rheumatic heart disease This lecture will discuss about rheumatic fever, latest diagnostic criteria (Revised by American Heart Association in 2015), and an overview of rheumatic heart disease. Echocardiogram
Murmur of subvalvular aortic stenosis is unlikely to radiate to the carotids. Murmur of supravalvar aortic stenosis may radiate more to the right carotid. Supravalvar aortic stenosis is
Aortic stenosis murmur and heart failure When the stroke volume falls in heart failure, the intensity of aortic stenosis murmur falls and may even be inaudible. This is
What is the phenomenon of pressure recovery in aortic stenosis? Phenomenon of pressure recovery in aortic stenosis: Systolic pressure in the aorta will be lower immediately distal to
Aortic gradient assessment by Doppler echo Normal gradient across aortic valve can be measured by pulsed Doppler echocardiography as the gradients are low. In the presence of aortic
Echocardiogram in Aortic Stenosis Echocardiogram is a very useful tool to assess aortic stenosis. It will identify whether the stenosis is valvar, supra valvar or subvalvar. Associated lesions
Gradient in aortic stenosis can be estimated from:
a. Sub costal view and PSAX
b. Apical 5C view and suprasternal view
c. PSAX view and PLAX view
d. Subcostal view and PSAX
