Aortic valve area calculation by the Gorlin formula is an indirect method of determining AVA based on the flow through the valve during ventricular systole divided by the systolic pressure gradient across the valve times a constant (44.3). The below equation relies on the ratio of peak-to-peak instantaneous gradients.

The systolic anatomic aortic valve orifice area (AVA) is the key parameter to establish the diagnosis of aortic stenosis severity (Table 13.2 ), apart from a transvalvular pressure gradient. The dedicated CT reconstruction path for AVA sizing is illustrated in Fig. 13.1. WebIf a patient presents with symptoms and the AVA is measured in the mild-moderate range alternative causes should be explored before attributing them to AS alone. References.
