This is called a bicuspid aortic valve.. Cardiac imaging for assessing low-gradient severe aortic stenosis. Distinction between these two entities is essential: patients with true severe AS generally will benefit from aortic valve replacement (AVR), whereas those with pseudosevere AS may not benefit [.
